What is the harm for flotation machine agent overdoses?

In the flotation process, we often ignore the risk of drug excessive.As the practice proving,there are many cases that the flotation index decline beacuse of the flotation reagents excessive, there are several aspects for flotation reagents excessive as follows:
1\the danger of the collecting agent.Firstly,destruct the selective of the flotation process.A large number of production practice and test proving,when the collector dosage exceed a certain range,then the concentrate grade would decline obviously.Even if the recovery rate is a little high,it can be more harm than good.Secondly,it will bring difficulty for the foam concentrate further selection and seperating the bulk concentrate if having excessive collecting agent.In this case,we often add more regulators to help a lot,for more regulators ,midding ore which containing excessive reagent will return to the procedure,mixing the flotation process,declining the flotation index,froming the vicious circle.Otherwise,Inhibitor dosage will increase following by the excssive collecting agent,which not only waste the reagents,but also increase content of the toxic drugs.Thirdly,the floatability of some mineral will decline because of the excessive collecting agent.For example,the excessive fatty acids collector will decline the floatability.This because collecting agent will form reverse layer of multilayer adsorption,polarity base towards outdoor,making the surface of the hydrophilic.Forthly,the excessive collector will form a large of bubble making difficult dewatering for concentrate and tailings,bringing difficult for thickeningand filtering.

2\the danger of  excessive inhibitor.when having excessive inhibitor,the mineral both wanting to flotate and being stopped will be stopped,making
 recovery rate decline.then,for improving the flotation ability of the flotation mineral,we should add more collector.
3\the danger of excessive activating agent.it not onlycan  damage the selective of flotation process,but also can have an effect with collector causing sediment,consuming large amounts of collector,for example,
4\the danger of excessive foaming agent,it can produce large of sticky and fine bubbles,make the gangue minerals easily adhere to the bubble,reduce the concentrate grade.If raw mineral has lots of slurry,it will from lots of sticky foam,cause dangerous accident.
The control of the reagent dosage plays an important role in improving the flotation process indicators,the excessive reagent dosage will damage the selective of the flotation process,increase the processing cost,and bring difficult for the flotation technology directly or indirectly.

What's the classification of flotation machine in mining industry?

    The classification method is not consistent, mine flotation machine according to different work principle are divided into four types that include Mechanical flotation machine, inflatable agitated flotation machine, inflatable flotation machine, gas precipitation flotation machine. Here are the details:

Mechanical flotation machine
Aeration and mixing of the pulp are achieved by mechanical stirrer, which belongs to outside air self-priming flotation. Its inflatable mixer is similar with the pumping characteristics of the pump, so it can absorb air and pulp itself.
Its characteristics are: First, 18 to 20 guide vanes are installed on the cover. Second, the impeller, cover, vertical axis, the intake pipe, bearings, pulleys and other components assemble into a whole. Third, a circle of vertical fin plates are installed in around the trough to prevent a swirl of slurry.

Inflatable agitated flotation machine
Its characteristics are: 1, the amount of inflation is easy to regulate separately; 2, decrease the abrasion of mechanical stirrer; 3, the opting indicator is better; 4, a lower consumption of power. 5, larger inflation; 6, an upwelling of slurry form.

Inflatable flotation machine
Its characteristics are: 1, without mechanical stirrer and transmission parts, its structure is simple, which makes maintenance and operation easily. 2, the size of inflation bubble is adjusted by the structure of inflator; 3, bubbles are mixed with the countercurrent pulp.

Gas precipitation flotation machine
Gas precipitation flotation machine is mainly used for mineral fine particle flotation and oily wastewater off of oil flotation.

The Knowledge About The Froth Flotation

What is the froth flotation?Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.Flotation of mineral is neither completely hydrophilic, nor absolute hydrophobic are often the intermediate state.the four stages for ore particle  close to bubble:
first,because of the function of the air agitation,pulp flowing, the surface gravity of the flotation,Ore particles and bubbles connect each other. the chances and the stirring intensity when ore particle and bubble close to each other,is related to the size of the ore grain bubble;
secondly,the connection between the particle and the bubble hydration layer;
thirdly,hydration shell getting thinner or bursting;
fourthly,particle is in touch with the bubble.

The particles with attached air bubbles are then carried to the surface and
removed, while the particles that remain completely wetted stay in the liquid phase. Froth flotation can be adapted to a broad range of mineral separations, as it is possible to use chemical treatments to selectively alter mineral surfaces so that they have the necessary properties for the separation. It is particularly useful for processing fine-grained ores that are not amenable to conventional gravity concentration. There are some factors affecting the froth flotation as fllows:
1 Performance Calculations,There is no one universal method for expressing the effectiveness of a separation, but there are several methods that are useful for examining froth flotation processes.
2 Hydrophobicity/hydrophilicity,The basis of froth flotation is the difference in wettabilities of different minerals. Particles range from those that are easily wettable by water (hydrophilic) to those that are water-repellent (hydrophobic).Particles can either be naturally hydrophobic, or the hydrophobicity can be induced by chemical treatments. Naturally hydrophobic materials include hydrocarbons, and non-polar solids such as elemental sulfur.
3 Particle/Bubble Contact,Once the particles are rendered hydrophobic, they must be brought in contact with gas bubbles so that the bubbles can attach to the surface. If the bubbles and surfaces never come in contact, then no flotation can occur.
4 Collection in the Froth Layer,The properties of raw mineral mixtures suspended in plain water are rarely suitable for froth flotation. Chemicals are needed both to control the relative hydrophobicities of the particles, and to maintain the proper froth characteristics. There are therefore many different reagents involved in the froth flotation process, with the selection of reagents depending on the specific mineral mixtures being treated.

how to select quality flotation machine?

Now ,I will tell you how to select quality flotation machine?
First of all,you should see the type of the machine.generally speaking,air-blowing mechanical flotation machines are appropriate for large-scale and super large-scale beneficiation plants ,
such as XCF air inflation flotation cell,KYF Air Inflation Flotation Cell.
Why do we choose these several types of flotation machine?Because these several types of flotation machine can regulate the volume,and it can not affect the mineral processing index,produced by the larger of the bearing initial for hard breathing, or the decreasing of gas quantity of unit volume.

Secondly,if you have a medium-sized beneficiation plants with low request for inflating volume,and easy choosing for mineral,we usually can choose agitation impler flotation cell,such as,SF Flotation Cell,BF Flotation Cell.The reason why we choose these several  agitation impler flotation cell is the few of the accessory equipment and the simple operation and maintenance,which is the best choice for medium-sized beneficiation plants.
Thirdly,choosing the correct flotation manufacturer.Xinhai Mining Machinery Group Company has more than twenty years production experience in flotation,and has its own mineral design institution,which has higher performance than the same type machines of others with its high wear-resistant rubber ensuring the devices are 2 times longer than others.
The last but not least,the all kinds of mining machine that Xinhai Mining Machinery producted,including ball mill,flotation cell(SF Flotation Cell,BF Flotation Cell,XJB Flotation Cell,and other flotation devices),thicking,crusher(Jaw Crusher,hammer crusher)and so on.

Introduction to Forth Flotation

   
    Froth flotation is regarded as the most important method of concentrating
minerals in the world. Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

    The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles.
The development of the method of froth flotation relied on the ingenuity and persistence of a variety of people including mine managers, chemists, metallurgists and mill operators.

 
     In conclusion, gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive.

The Main Challenges Faced by the Mining Industry at the Moment

    As far as I am concerned, the main challenges faced by the mining industry at the moment is to choose a good turn-key service to improve the efficient,and increase the interests.the development experiences of Third World countries since the fifties have been staggeringly diverse—and hence very informative. Mining is one important economic engine for some countries more than others.
    The cyclical economic downturns exposes a fundamental business problem. When money is cheap, the essential problem is not what to do, but why aren't you doing. When money is expensive -as it currently is- the problem is how can we keep making business with what we have.

    I think, the uncertainty of when this cycles starts and finishes, the high uncertainty in commodity prices, and, the frantic race to show juicy blue numbers for stockholders each yearly-quarter severely restrains mining companies to develop smarter and longer-term strategies. That's a big problem right there. How can you do it better?There are four reasons for you to refer to:
1.- China's economy slowing down
2.- Low liquidity, high debt
3.- Capital allocation
4.- Social license in developing economies/water & environmental issues
    Xinhai Mining Group Company not only has a large domestic mining market, but positively participates various investments and services in oversea market.What you need is what we can do! It is not only a promise but the strength of Xinhai Company. We sincerely hope to join hands with you for a bright future!

Five maintenance methods for flotation?

Flotation is one of the common mineral processing machinery and equipments,but it is easy to be frayed,we should warn the operators to operate it according to operating instructions, and realize the importance of maintenance.

1、Checking the air intake,the air intake has an important effection on the performance index of the flotation devices,but, the more the air intake,the less the wear and tear of impeller and the cover plate,so,we often use the anemograph to check the air intake of the flotation in production.
2、Replacement of wearing parts, we should adjust the inner ore of impeller to adjust the air intake, according to the attrition rate of the ore,impeller and the cover plate.
3、Adjusting the height of  the liquid level.we should uitilize the liquid level regulator to adjust the height of the liquid level,to assure scraper blade scraping the bubble efficiently,avoiding the pulp overflow into the foam tank.
4、Adjusting the ore,through the lever to adjust the opening of the door,Ensuring the slurry balance, and avoiding rough mortar deposite in the studio.
above showing us the mintainence methods of flotation devices, we should pay attention to these matters in the process of the flotation maintainence, in order to operate the flotation of ore efficiently,and extend the service life of flotation machine.
