METHOD FOR PROCESSING OF SUSPENSION OF CLAY-SALT SLIME OF POTASSIUM PRODUCTION Russian patent published in 1995 - IPC

FIELD: utilization of clay-salt of potassium production. SUBSTANCE: clay-salt slime of potassium production is preliminarily treated with flocculant-polyacrylamide in two stages, and, at least, in one static mixer. In this case, head loss-to-head rate of treated suspension ratio at the first stage amounts to 200-850, and at the second stage, 40-130. Amount of polyacrylamide supplied at the first stage is 7-20% of its total amount. EFFECT: higher efficiency. 2 tbl
