【摘要】 以老挝钾盐矿提钾后的尾盐、母液为原料,以老挝当地产的白云石粉为凝结剂,考察了回填料的流动性、耐水性、耐候性、胶结性、抗渗性,并对回填料做XRD、能谱、电镜分析。结果表明白云石粉是适宜于老挝钾盐矿副产物回填的有效凝结剂。更多还原

【Abstract】 Study was conducted on the fluidity,water resistance,weather ability,cementation and impermeability of backfill and analysis was made of backfill by XRD,energy spectrum and electron microscope taking tail salt and liquid potash after potassium extraction in a potash mine of Laos as raw material and dolomite powder from Laos as coagulant.The results showed that the dolomite powder is an effective coagulant for by-product backfill in the Lao potash mine.更多还原
