| abstract | The exploitation Application way that the invention provides a kind of polyhalite-halite accompanying mineral deposit is: in polyhalite-halite accompanying mineral deposit, inject fresh water, and leach bittern stoste, the Na ion concentration of described bittern stoste is greater than 79g/L, and potassium concentration is greater than 4g/L; Described bittern stoste and lime slurry are reacted, adds sodium carbonate solution after filtration, be purified bittern; By described purified brine evaporation concentration, control sulfate ion concentration and be greater than 20g/L, obtain thick sodium-chlor and concentrated brine; Described concentrated brine is obtained thick nitre through freezing and freeze nitre mother liquor; Describedly freeze nitre mother liquor vacuum evaporation, control potassium concentration and be greater than 80g/L, obtain thick sodium-chlor and salt-making mother liquor; By described salt-making mother liquor cooling down, obtain thick Repone K and analyse potassium mother liquor.Operation of the present invention is reasonable, makes accompanying mineral deposit obtain maximum using.Simple to operate, cost is low, and yield is high, not only reduces the cost of winning of polyhalite, also achieves the comprehensive utilization of resource. |
