what is the difference between taconite and iron ore gold

Iron ore - Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and ...

What do you know about hazardous waste?: Acid Mine Drainage - Blogger

What is acid mine drainage? Well, mining means that rock is being removed to uncover valuable minerals like gold, copper, iron or coal. It is safe to say that most of this rock has not been exposed to oxygen for a long time, if ever, and therefore have been in a state of anaerobic conditions. The process of exposing minerals like pyrite to oxygen is called oxidation.
