Description:
"The Bureau of Mines investigated techniques for dewatering slurries from talc-processing operations to improve water reclamation and produce dewatered solids suitable for disposal. Various flocculating reagents were evaluated, and a nonionic polyacrylamide was found to be most effective in a specialized flocculation dewatering technique. The flocculation dewatering method was applied in laboratory batch tests and in continuous tests using a static screen, a belt-roller device, and a clarifier-thickener laboratory unit. In continuous tests using the unit, wastes of 3.5 pct solids were dewatered to 56.9 pct solids using 0.03 Lb of flocculant per ton of dry solids treated." - NIOSHTIC-2
