FIELD: mining industry.
SUBSTANCE: clarification of the saponite clay suspension. Invention relates to a method for clarifying saponite clay suspension and can be used to separate suspended solids from saponite clay suspension at mining enterprises. The method is carried out by introducing an additive into the saponite clay suspension and subsequent separation of the solid phase, moreover, iron(II) sulphate and ferrosilicon are used as additives, the separation of the solid phase from the supernatant liquid is carried out after preliminary settling, and the precipitate, if necessary, is compacted by centrifugation.
EFFECT: acceleration of the process of clarification of the saponite clay suspension, as well as a significant reduction in the cost of subsequent centrifugation.
