Phosphate contributes significantly (59%) to the NPK compound fertilizers formulation in Zimbabwe. Phosphate is a vital major nutritional component required by plants and as most soils in Zimbabwe are phosphate deficient, the phosphate industry is critical to agriculture.
Chemplex Corporation manufactures superphospates for fertiliser production, through the Zimbabwe Phosphates Industries (ZimPhos) company located in Msasa, Harare.
The factory produces single superphosphates (SSP) and triple superphosphates (TSP) from sulphuric acid, phosphoric acid and phosphate rock concentrate. These products are sold to ZFC and Windmill for production of NPK fertiliser compounds. ZimPhos currently now produce D Blend, Compound D and AN.
Under normal situations, ZimPhos is able to meet the country’s phosphate requirements.
Monocalcium phosphate (MCP) is also produced in the same plant from phosphoric acid and limestone and is used as a source of phosphates for stock feeds in the husbandry and poultry industries.
