Positive and Negative Effects of Mining

· Mankind started mining for precious metals between 20,000 and 40,000 years ago. For the last century, mining has been one of our planet's largest industries (it generated 683 billion dollars in revenue in 2018 alone). This only underscores the fact that our desire for precious metals and minerals has grown exponentially since we first started digging through the topsoil to get at raw and ...

Metallurgy

Mining may not be necessary, if the ore body and physical environment are conducive to leaching. Leaching dissolves minerals in an ore body and results in an enriched solution. The solution is collected and processed to extract valuable metals. Ore bodies often contain more than one valuable metal.

Sulphuric acid leaching of zinc and copper from Nigerian Complex Sulphide Ore .

the metal value is preferably extracted directly from the lowgrade ores through a hydrometallurgical process. However, sulphide ores do not allow the recovery of metal by direct chemical leaching (Hiskey and Wadsworth, 1975; Dutrizac, 1989), due to their low solubility in most leaching reagents. In such cases, ore must be pretreated in

· The characterization and H 2 SO 4 leaching behavior of a Nigerian ilmenite ore following mechanical activation and alkali roasting were investigated. The effects of NaOH/ore ratio, H 2 SO 4 concentration, leaching and roasting temperature on the Ti recovery from the milled ore were examined. The results show that mechanical activation significantly enhances the dissolution of ilmenite ore.
