Conventional mining methods adapted from coal and hard-rock mining operations and machine mining are employed to mine ores to a depth of ca 1100 m. Solution mining is employed to recover potassium chloride from deposits exceeding ca 1100 m or from deposits that cannot be mined conventionally because of geological anomalies.、Although it is a relatively small source in terms of total world production of potassium chloride、significant tonnages of potassium chloride、ca 3% of world production、are produced by solar evaporation of natural brines.、(1) Mined from sylvite deposits in New Mexico and Saskatchewan、purified by fractional crystallization or floatation、(2) extracted from salt lake brines and purified by recrystallization.、Extracted from bedded deposits of salts、or from concentrated surface and、or subsurface brines、followed by milling、washing、screening、flotation、crystallization、refining and drying、Impurities: Contaminants: Magnesium sulfate salts、Chemical grade KCl、Industrial & Refined grade: Na、Br、SO4、Ca、Ca & Mg、Pb、Fe、Cu、Ni、Cr、Mo、V、Ti、Impurities are usually sodium chloride and magnesium chloride、NaCl、bromide and alkaline earth sulfates、depending on the raw material and production process、Formulations、Preparations: Grades: Chemical (99.5 and 99.9%)、agricultural grades sold as 60-62%、48-52%、and 22% K2O、single crystals、United States Pharmacopeia、FCC.、Pure KCl-95 wt% KCl equivalent、Fertilizer grade is 95-96% KCl and is available in three sizes、standard、coarse and granular.
