cyanate, dissolved organic carbon, copper and zinc were possible toxicants in a gold mine effluent. Therefore, a bench-scale toxicity treatment evaluation (TTE) of a gold mine effluent was investigated. The objective was to produce a treated effluent that is non-acutely lethal (non-toxic) to rainbow trout and . Daphnia magna.
and the ground water in the gold mining areas all round the world as the high content of arsenic in the surface as well as in the ground water is hazardous to the human beings and the several species who are the habitat of that particular miningarea.

A gold mine effluent is sampled at the inlet of an operating treatment plant. The effluent is alkaline (pH 7.5-8.4) and contains high concentrations of SCN- (435±53 mg/L) and NH3-N (41±8 mg/L).
A feasibility study on the production of gold at a fictitious mine (Moapa mine) in Elko County, Nevada is to be performed. The mine is capable of producing 325,800 tons of high-grade ore per year for 8 years. The deposit contains 0.12 ounces of gold per ton of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore
