Toronto-MagMinerals Inc. , a unit of MagIndustries Corp., has selected HPD, Plainfield, Ill., to provide evaporation and crystallization technology for the company’s Kouilou Potash Project located in the Republic of Congo, near the Atlantic port city of Pointe-Noire. The project is based on the solution mining of the company’s carnallite salt deposits and is in the final stages of a feasibility study being led by SNC-Lavalin International Inc. HPD will provide a brine concentration system to reconstitute the carnallite directly from the solution mining operations. The concentrated carnallite is then processed in a multi-stage crystallization system to produce potassium chloride. The plant’s nominal capacity is rated at 580,000 mt/y of potash. The company said HPD was awarded the project due to their extensive experience in potash installations and expertise in crystallization process design for chemical production applications. MagMetals, MagMinerals’ sister company, is planning the development of a 72,000 mt/y magnesium smelter adjacent to MagMinerals’ potash plant for the production of magnesium alloys for the global automotive industry. The raw materials for the MagMetals plant will be sourced by solution mining as well.
