25.1 Exploration: Finding minerals Mining of mineral ...

The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:

Acid mine drainage formation, control and treatment ...

2019-1-1  Acid mine drainage (AMD) is a worldwide concern in coal and metal mining. Mine planners must predict AMD potential before disturbance. If AMD is predicted, planners must install control measures such as spoil handling plans, alkaline amendment, and covers. Treatment of AMD uses chemicals such as Ca (OH) 2, CaO, NaOH, Na 2 CO 3, and NH 3.
