A PROCESS FOR THE MANUFACTURE OF DOUBLE SULPHATE OF POTASSIUM AND MAGNESIUM (POTASSIUM SCHOENITE FROM MIXED) SALT OBTAINED FROM SEA BITTERN

摘要

A process for the manufacture of double sulphate 01 potassium and magnesium /potassium scboe-nite) from mixed salt obatained from sea bittern which consists in separating potassium chloride and magnesium sulphate from the mixed salt by flotation using as flotation agents octadecylamine acetate and highly sulphonated castor oil to obtain a floated product consisting of potassium chloride and magnesium sult-phate which is converted to double sulphate of potassium and magnesium by adding 40% water by weight at 26 G.
