The gravity in the mineral processing production function can be summarized as follows:

1矿石预选，在粗粒或中细粒条件下，预先选出部分最终尾矿，以减少主选入选矿量，降低生产成本。

1 ore selection, in the coarse or fine grain conditions, the pre selected part of the final tailings, in order to reduce the main ore selection, reduce production costs.

2矿石的主选，将有用矿物与脉石或围岩相分离，得到最终精矿和最终尾矿（或中矿）、

The main ore 2, separation of useful minerals and gangue or rock phase, the final concentrated ore and tailings (or mine),

3与其他选矿方法组合成联合流程，进行有用成分的综合回收或粗细粒级分别处理。

3 and other mineral processing methods combined into a combined process, the comprehensive recovery of useful components or coarse grain grade treatment.

4选矿的补充作业，在主流程之后补充回收伴生成分，

4 supplementary operation of mineral processing, after the mainstream process to supplement the recovery of associated components,

重力选矿的应用正在日益扩大，除用于分选传统的矿物原料外，也用于工业废渣和工业垃圾的处理，同时也用于老尾矿的在回收。

The application of gravity concentration is increasing day by day, in addition to the traditional mineral raw materials, it is also used in the treatment of industrial waste and industrial waste.
