Method for green-producing high-quality calcium superphosphate co-generated magnesium chloride by low-level collophanite

InactiveCN106517124AReduce contentSolve problems such as poor qualitySuperphosphatesMagnesium chloridesDecompositionCarbonate
The invention relates to a method for green-producing high-quality calcium superphosphate co-generated magnesium chloride by low-level collophanite, comprising steps of a, performing acid splitting on carbonate in the phosphorite by hydrochloric acid and preparing phosphorus concentrate; b, preparing high-purity calcium sulfate; c, preparing magnesium chloride; after concentrating the filter fluid to a certain volume, preparing magnesium chloride. The invention has the advantages that the method is applicable to prepare high-efficient phosphatic fertilizer by directly producing high-quality low-magnesium phosphorite in hydrochloric acid decomposition, carbonate of low-level phosphorite and in particular to high-magnesium phosphorite; no waste discharges during the whole technical flow; by applying the invention, the phosphorus pentoxide content of phosphorite is promoted through one acidolysis while content of magnesium oxide in the phosphorite is also reduced; thus the problem of agglomeration and poor phosphatic fertilizer quality caused by high magnesium content during the ordinary calcium production can be solved; the phosphorite therefrom is directly reacted with sulfuric acid, thus high-quality phosphatic fertilizer of which available phosphorus is improved to 16-18% P2O5 can be obtained.
