With mining capacity continuous increase and with mine entering into deep mining stage, the grade of crudeore and the grindability of ore decrease that raise the cost of grinding.
随着矿山规模的不断扩大和进入深部开采，矿石的原矿品位和相对可磨度逐渐降低，磨矿成本随之升高。

In technology, four process schemes, such as crudeore cyanide leaching, flotation -cyanide leaching of flotation concentrate, fractional bulk flotation and selective flotation, were put forward.
The crudeore of kaolin is added with water into pulp, the disperser is added for dispersing, and then the flocculation accelerator is mixed, then the selective flocculation separation is undergone.
