Mining

The application of anionic polyacrylamide involves mining, mill running and metallurgy. Polyacrylamide can promote the rapid sedimentation of  solid material, accelerate the inspissations of remote objects, enhance solid-liquid separation effect, decrease gangue losses and pollution for the purpose of  reducing production cost.

In general cases, the processing course of material needs high molecular products to guarantee a rapid sedimentation rate, a good effect of centrifugal processes and easy to gain better economic domino effect.

There are virious ionic degree and molecular weight. Customers can  choose the most suitable products on their own. On the other hand, we can also arrange production on customers' option. 

1.Coal Industry
 Coal need to be classified and separated according to the different granularity and the various proportion of coal granule and impurity in water. With the coal floating above and the impurity sinking into the bottom of water, the coal is gained after the process of classification. 

Coal powder, gathered from the above process, needs further disposal, by the flotation craftwork process. The refining coal floats, and the other sinks by using flocculants. In this progress, anionic polyacrylamide is used as flocculants agent to promote the solid-liquid separation, then in the following filtration and centrifugation progress, it is used again to promote the solid-liquid separation.
The applicable products are as following: BMFLOC A0714C BMFLOC A1414C BMFLOC A1418C BMFLOC A2020C、BMFLOC A3016C、BMFLOC A3018C、BMFLOC A3020C、BMFLOC A3026C、BMFLOC A4014C、BMFLOC A4026C
BMFLOC N706、BMFLOC N710 

2.Bullion
  The minerals, after crushability and separation, are further ground by adding water and calcareousness by using Muller and carry through the sedimentation in the next step concentrator. In this period, using anion polyacrylamide accelerates the quick sedimentation of solid and the substrate sludge is leached by a series of filter tanks.

The anionic polyacrylamide flocculants that are added in the concentrator before filtration are as following:

The applicable products are as following: BMFLOC A0714C BMFLOC A1418C BMFLOC A2020C BMFLOC A3020C、BMFLOC A3026C

3.Lead-Zinc
    In the sorting craftwork of lead and zinc: the mineral zinc is oxidized into zinc oxide after calcimining. Then lixiviate the oxide by vitriol. The neutral filtration with the about 5 PH and acid filtration with the 2.5 PH can make all head coal dissolve in the vitriol. Some mill run factories increase the heat filtration concentration process to further improve callback rate. The antidromic circumfluence sedimentation system is generally used in the flooding purification of the neutral concentration.

In the filtration craftwork of lead and zinc, using anionic polyacrylamide as the flocculants accelerates the quick sedimentation of minerals and clarification of filtration, improves the process production efficiency, and reduces the loss of mineral.
The flocculants, used in the neutral filtrate, are as following: BMFLOC A0714C BMFLOC A1414C BMFLOC A1418C
The flocculants used in the acid filtrate are as following: BMFLOC N706 BMFLOC N710 BMFLOC N714

4.Aluminums Ore 
 In the course of aluminum ore processing, the minerals are crushed into less than 1 mm level, then add the dense sodium hydroxide conditions of high temperature and high pressure. The aluminum dissolves in the high corrosive liquid; however other impurities ,except the soluble silicon, can not be dissolved.

After the previous course, the grit and the pulp that are left after the primary inspissations and sedimentation, are together removed. Adding the anion polyacrylamide flocculants into the concentrated tank is the most important craftwork of receiving clarified flooding. The bottom flow in the concentrated tank (red mud) will be disposed by back flow sedimentation craftwork. The aluminums in the liquid among this craftwork are reclaimed after a series of lavation sedimentation ponds. At this time, anion polyacrylamide flocculants are reused for accelerating quick sedimentation and receiving the satisfied clarified flooding.

The primary concentrated tank flooding rich in aluminum after filtrating and cooling (48hr.) accelerates the sedimentation of aluminous trihydrate with adding aluminous hydrate. Then the aluminums are received after filtrating and lavation.
The applicable products are as following:  : BMFLOC A8514C、BMFLOC A8516C、BMFLOC A0014C

5.Copper
    The pulp or gangue from flotation cell will be put in the sedimentation pond for further sedimentation. Here ,add flocculants, accelerates the quick sedimentation and produces the clarified flooding that used as cycle water, and putting the remaining concentrated gangue into the centrifugal machine for centrifugal dehydrator. This time the anion polyacrylamide flocculants will be added in as the centrifugal additive.

    By the manner of mechanism separate the bleb (concentrate) that carrying the copper from flooding, and then concentrate and dehydrate it. Here the anionic polyacrylamide flocculants is used to improve the efficiency of sedimentation and filtration. The finally received concentrate or filter cake contains nearly 25%~35% copper, which will be reclaimed by high temperature metallurgy.
The sedimentation products that apply to concentrate and flotation gangue are as following: BMFLOC A0714C BMFLOC A1418C BMFLOC A2020C BMFLOC A3026C

The flocculants that used in the concentration  are as following: BMFLOC A1414C、BMFLOC A2020C、BMFLOC A3026C、BMFLOC A4014C、BMFLOC A4026C、BMFLOC A4814C、BMFLOC A4826C、BMFLOC A8514C、BMFLOC A8516C、BMFLOC A0014C
