ABSTRACT:
The present invention related to the use of certain cross-linked diallyldimethyl ammonium chloride polymers in water-in-oil emulsion form for use as coagulants in suspensions of inorganic solids. The diallyldimethyl ammonium chloride polymers are preferably polymers of diallyldimethyl ammonium chloride, acrylamide, and triallylamine. The water-in-oil emulsions are formulated to invert after addition to the inorganic solids suspension, as the suspension travels to a mechanical thickening device for further processing. The inorganic solids from refuse or concentrate mineral processing applications may be coal, copper ore, sand, gravel, taconite, beryllium, trona, kaolin or precious metals.
