摘　　要：由于钾长石矿含硅高,如直接采用碱石灰烧结法提铝、钾则存在产出渣量大等问题。对钾长石矿进行了预脱硅试验,考察了反应温度、液固比、反应时间、碱浓度、钾浓度、粒度、转速因素对硅、钾浸出率影响的条件试验,并得到了预脱硅的最佳综合条件。Because of the high silicon containing potassium feldspar, there is a large amount of slag and other problems if soda lime sintering process is used to recover aluminum and potassium. The conditions of reaction temperature, liquid solid ratio, reaction time, NaOH concentration, K2O concentration, particle size, rotational speed factor on silicon and potassium leaching rate were investigated, and the best synthesis condition of pre-desilication was obtained.
