Process control challenges and opportunities in mineral processing

 · The operator monitors the load in the mill and the power and evaluates how they are performing together. They should trend the same. If you have more or less load in the mill, then you should be using more or less power (if the hardness of the ore is the same). If the trends diverge, then something has changed.

Pollution From Mining

 · The water pollution is caused by acid that drains from the "Iron Mountain" mine, known as acid drainage. Acid drainage is serious stuff. With a pH value of 0, the groundwater near the "Iron Mountain" has been found to be 10,000 times more acidic than battery acid (this is VERY acidic). It''s the highest concentration of acid in the world.

Why Mineral Processing is Very Important for the Mining Industry

Mineral processing removes impurities from the ore and allows to produce of a clean product of higher quality. For example, silica sand for metallurgy applications that contains iron impurities less than 0.1% has a higher price than which includes more than 0.1%. But, an amount of 0.3% iron or higher isn''t acceptable.

Pollution from Mining

Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.
