Calculation of technological losses in washing of gold-containing sands
Calculation of gold losses is considered in washing of placer sands. Technological losses are revealed because of inadequate degree of disintegration of clayey material of sands and the losses connected with imperfection of equipment and concentration operations. Calculated formulae are recommended for determination of gold losses during concentration in sluices and settling machines. According to published data graphic comparison is given of calculaed values and values of coefficient of losses.
