Tin Ore Mining Process – JXSC Mineral
Tin Ore Processing. Crush the raw ore to 20mm, then screen it into two particle sizes, (20mm~4mm) and (4mm~0mm). Put the 20~4mm ore into a heavy medium cyclone to be selected. Then the ore will enter the rod mill. After that, it will be preselected in the jig.

Extraction of Zinc: Process, Ores, Diagram
The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

The froth is skimmed off and the resulting zinc sulphide concentrate is dried. This process upgrades the ore, which may contain only 6% zinc, to a concentrate assaying more than 50% zinc. Up to 90% of the zinc in the ore can be recovered. Electrolysis and smelting are the two processes used to produce zinc metal. In Australia, the electrolytic ...
