The present invention is directed to a novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern. The process requires bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern, and is converted to schoenite which is subsequently reacted with muriate of potash (MOP) for its conversion to …

1. A process for recovery of potassium from bio-methanated spent wash (BMSW) with concomitant improvement of process effluent quality comprises the steps: (i) treatment of BMSW (containing ca. 2% K + w/v) with sulphuric acid under stirring till pH is ca. 1.5; (ii) addition of aluminium sulphate solution to the slurry from step (i) under stirring, to maintain Al 3+ …

A novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern is disclosed. The process requires only bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern. Kainite is convened to schoenite with simultaneous removal of NaCl by processing it with ...

A novel integrated process for the recovery of sulphate of potash (SOP) from sulphate rich bittern is disclosed. The process requires only bittern and lime as raw materials. Kainite type mixed salt is obtained by fractional crystallization of the bittern.

We claim: 1. An integrated process for the production of sulphate of potash (SOP) from sulphate-rich bittern from kainite type mixed salt, said process comprising the steps of: (i) treating the mixed salt with an appropriate quantity of water in the first batch to leach out NaCl, under ambient conditions and simultaneously converting kainite into schoenite, (ii) filtering the resultant ...

Kainite is obtained by fractional crystallization of the bittern. Kainite is converted into …

The Mackay sulphate of potash project is located in Western Australia, approximately 785km south of Wyndham Port. Image courtesy of Agrimin. The project will extract sulphate of potash minerals dissolved in the brine within Lake Mackay. Image courtesy of Agrimin. The definitive feasibility study will be completed by June 2020.

Sulfate of Potash 0-0-50-17S (Potassium Sulfate) The Sulfate of Potash that is in our blends and that we sell as a straight material is extracted for Utah's Great Salt Lake, which is the safest and most effective form of Potassium. Activated by solar evaporation, the natural process removes crystallized nutrients from ponds fed by the lake.
