Iron ore is an important iron and steel producers of raw materials, natural minerals (iron ore) after crushing, grinding, magnetic separation, flotation, gradually re-election and other procedures selected iron. In theory aspect, any compound containing iron or iron ore can be called the iron ore. The process of roast working of the shaft furnace is to send the ores to the shaft furnace to be roasted, which can separate the ores to the waste rocks and valuable ores. The waste rocks are sent to the hillock by the belt conveyor and the winching system, while the valuable ores are sent to the weak magnetic cylindrical ores bin as the product of the materials of weak magnetic separation.

Steps for ore separating line:

Digging ore from the earth is only half the battle. The processing of the ore is often just as challenging and expensive, which takes place in refineries, smelters and mills. Ore processing consists of the following stages:

1. Crushing and grinding of the ore;

2. Addition of processing water (generally decanted from the tailings pond) to form a slurry;

3. Addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution;

4. Addition of carbon to adsorb dissolved metals and remove them from the slurry;

5. Stripping the metals from the carbon by acid washing and circulation of a caustic cyanide solution;

6. Precipitation of the gold and silver by electro-winning;

7. Smelting of metal products into bars;

8. Pumping of the barren slurry (tailings) to the tailings storage facility.

The final purpose and task of ore dressing is to separate the ores from the useless gangue minerals, separate and collect the symbiotic valuable minerals to sole concentrate, recover the valuable element comprehensively, eliminate the impurities doing harm to metallurgy or other process, improve the quality of ore dressing product, in order to reach the object of making use of mineral resources more sufficiently, reasonably and economically.
