  • Use of chitosan as a clarification aid for mining ponds
    Publication number: 20060000783
    Abstract: A method of clarifying a slurry in a mining pond is described and claimed. The slurry contains water and mined solids. The method uses chitosan, optionally formulated with an inert fluorescent tracer, to clarify the slurry in a mining pond. This clarification process causes mined solids to settle to the bottom of the pond leaving the water less turbid than before the application of chitosan.
