【摘要】 测定了难洗矿石的原矿性质，分析了矿石难洗的原因，利用自制的洗矿模拟设备，分别研究了添加化学药剂和添加铝土矿净矿石自介质对洗矿效果的影响。结果表明，盐酸、硫酸锌、石灰等无机化学药剂和淀粉有机药剂能够明显改善洗矿效果，而分散剂类药剂不能改善洗矿效果。添加矿石自介质也能够明显提高洗矿效率。更多还原

【Abstract】 The properties of the hard to wash run of mine ore is tested,the causes for hard washing are analysed and the effect on the washing results of adding chemical agents or clean bauxite ore as autogenous medium is studied on a self made imitator of ore washing.The results have shown that inorganic agents such as hydrochloric acid,zinc sulfate and lime and the organic reagent starch can remarkably improve the washing effect while dispersant reagent can′t.Addition of ore as the autogenous medium can also effectively improve the washing efficiency.更多还原
