Product Description
Polyacrylamide for Mineral Processing Industry
In most mineral processing where there is a flocculant requirement for either sedimentation or centrifugation,then a high molecular weight polymer is desired.
WELLDONEFLOC anionic polymer has ultra high molecular weight which ensure best performance and cost efficiency for sedimentation or centrifugation.We are manufacturering full range of anion/cation polymers from low to high for all kinds of processing need. 
WELLDONEFLOC polymer is widely used in mineral processing industry,such us

Product Application
Polyacrylamide for Coal Washing
After the coal is mined and sized it is then ground down by ball mills and then separated from the waste by gravity in a medium of water.The coal floats and the waste sinks with the subsequent coal again sized and separated into the finished product.
During the process fine coal particles are generated which require further processing to recover these fine coal particles.This is normally achieved by a flotation process where a flotation agent is added to promote the separation of the coal from the waste.Again the coal floats and waste sinks.The fine coal is then recovered by sedimentation and then by filtration or centrifugation.Flocculants are used in the sedimentation process to promote solid liquid separation and subsequent rapid settlement in the thickeners so by producing clean water from the overflow of the thickeners for recycling back to the preparation plant.The fine coal,which settles,is subsequently recovered by filtration/centrifugation as the fine grade coal product.Again during the filtration/centrifugation process flocculant ia added to enhance the separation process.
When processing brown coal,or coal with high clay content,it is sometimed necessary to use a coagulant prior to the addition of a flocculant for settlement applications so as to achieve efficient solids capture and an acceptable overflow clarity.

Polyacrylamide for Gold/Silver
Most Gold and Silver processes of extracting he mineral by using either Carbon in Pup (CIP) or Carbon in Leach (CIL) processes.The activated carbon dissolved in cyanide is used to recover Gold/Silver.
Before leaching,crush and screen the mineral first,then go through ball mills with water and lime.Add flocculants in each thickener to speed up the flocculation,and the underflow will go through series of leaching tanks for leaching which will offer longer time of dissolving in cyanide solutions.
The mineral slurry passes through series of carbon adsorption tanks where the gold and silver are extracted from solution.This is done by adding activated carbon in opposite direction of slurry flow,Gold/Silver will be extracted by activated carbon particles.
This loaded activated carbon is pumped to the elution tank where the Gold/Silver are washed off with superheated water.The washed solution is passed to the electrolytic tank for metals recovery.

Polyacrylamide for Copper
The ore is crushed and ground to separated the copper-bearing mineral from the wasted materials or gangue.The separated ores will be further crushed by ball mills.The final material particle size will be less than 100 microns
During the final milling collectors are added to the slurry which preferentially absorb the copper sulphide and make the sulphide particles hydrophobic.These copper minerals are then concentrated by flotation when air bubbles are pumped into the slurry.Frother is normally added to the slurry to stabilize the copper particle to be loaded in bubbles at the top of the slurry when creating froth.The slurry or tailings from the flotation lagoons will be delivered to thickener where flocculants are added to promote rapid sedimentation and generation of a clear overflow,which returns to the process water circuit.The thickened tailings are normally further dewatered by filtration where a flocculant is added as a filtration aid.
The copper laden froth (copper concentrate) is removed from the overflow by mechanical means and is then thickened and dewatered where flocculants are used to improve the sedimentation and filtration rates.The resultant concentrate or cake contains approximately 25 to 35% copper,which is then recovered by pyrometallurgical processing.

Polyacrylamide for Alumina
Processing bauxite ore produces alumina.After crushing and grinding the ore to less than 1mm it is then subjected to high temperature and pressure after the addition of concentrated sodium hydroxide.The alumina dissolves in the highly caustic liquor and only silicon is soluble among all the impurities.
After digestion the sand particles are removed with the slurry being settled in primary thickeners where the flocculant ia added.This ia a critical stage in achieving very clear overflow clarities.The underflow,or red mud,then passes to a counter current decantation process where further alumina from the liquor is recovered via a series of washer decanters.Again flocculant is used here to promote settling and get a clear overflow.
The high aluminum content liquor from the primary thickeners is filtered,then cooled (tanking up to 48 hours) and seeded with alumina hydrate to promote precipitation of alumina trihydrate.Filtering,washing and cleaning to produce alumina.
