Addition of ore as the autogenous medium can also effectively improve the washingefficiency.
添加矿石自介质也能够明显提高洗矿效率。
2
As the washing procedure continues, impurities accumulate in the alkaline solution and cause a decrease in washingefficiency, and even make it invalid.
碱洗液随使用时间的延长，其中会累积大量杂质，造成碱液清洗效率下降而失效。
