Tin Ore Mining Production Line

Process Description

• 01

  Crushing and Screening

  Crush the raw ore to 20mm, then screen it into two particle sizes, (20mm~4mm) and (4mm~0mm).

• 02

  Preselecting

  Put the 20~4mm ore into heavy medium cyclone to be selected. Then the ore will enter into the rod mill. After that, it will be preselected in jig. The tailings over 2mm will be abandoned, and the ore below 2mm will be put into shaking table.

• 03

  Bulk Flotation

  The concentration from jig and shaking board will be separately selected by bulk flotation. The tailings will enter the shaking board to get qualified tin concentrates.  

• 04

  Separating Flotation

  After the bulk flotation, the concentrate will be fine grinded, then will be do the flotation separation of lead zinc ore. After that Lead antimony concentrates and zinc concentrates will be produced.  

• 05

  Gravity Separation

  The tin pulp enter into Φ300mm hydrocyclone, then overflow to Φ125mm and Φ75mm hydrocyclone group to remove the fine mud. The sand setting will enter into the process of thickening, desulphurization by flotation, and then cassiterite flotation.
