【摘要】 光卤石分解过程中的加水量决定着钾的转化率和收率,加水量可根据光卤石矿中的镁含量来计算。随着光卤石矿品位的变化,加水量应做相应的调整,一般通过分析分解固相和液相离子的组分来判断加水量是否合适,但是这种方法非常耗时。研究了不同加水量对光卤石分解固相中镁含量和含水量的影响,利用分解固相中镁含量与含水量的关系,确定光卤石的分解状况。结果表明:加水量过小,固相中镁含量与含水量呈非线性变化;加水量过大,固相中镁含量与含水量呈线性变化。这种利用分解固相中镁含量与含水量的关系来确定加水量是否适宜的方法简捷、快速、有效。更多还原

【Abstract】 Quantity of water-adding in carnallite decomposition process determines the conversion and yield of potas-sium,and quantity of water-adding can be calculated by magnesium content in carnallite.Quantity of water-adding should be adjusted with the changing of carnallite grade.In general,the suitability of water-adding was estimated by analyzing ionic composition of solid phase and liquid phase in carnallite decomposition process,but the analysis detection time in this process was too long.Influences of different quantitues of water-adding on moisture content and Mg content in solid phase of carnallite decomposition process were studied,and carnallite decomposition status can be ensured by using the relationship of Mg content and moisture content in solid phase of decomposition process.Result showed that Mg content and moisture content in solid phase had nonlinear variation when water-adding was insufficient;too much water Mg content and moisture content in solid phase had linear change.This method for confirming the suitability of water-adding quantity by the relationship of Mg content and moisture content in solid phase of carnallite decomposition process is simple,fast,and effective.更多还原
