Copper extraction refers to the methods used to obtaining copper from its conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Tin is one of the basic chemical elements. When refined, it is a silverywhite metal known for its resistance to corrosion and its ability to coat other metals.
Smelting Once the waste materials have been physically removed from the ore, the remaining copper concentrate must undergo several chemical reactions to remove the iron and sulfur.

The success of the copper and tin mines in Cornwall created a demand which led to the establishment of local ancillary industries, like smelting. But how did the smelting process work, and what impact did it have on the local economy?
Some prospectors are interested in the methods of processing sulfide ores to extract their values. The two of the best known processes are smelting and roasting.
Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to .
Copper refining requires putting mined rock through several processing stages. Here's a brief overview of how that happens.

Millions of tonnes of lowgrade ore and copperrich tailings await the development of an efficient and economic bioleach process for chalcopyrite (CuFeS 2).The bioleaching of chalcopyrite in situ and in dumps is a practical option only because the low and slow recoveries are countered by the low processing costs (Schnell, 1997).Not surprisingly, the bioleaching .
Smelting is a process of applying heat to ore in order to extract out a base is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base .
How Minerals Are Extracted From Earth. In a previous lesson, we learned about minerals, which are inorganic compounds, such as ores (like copper) and precious stones (like diamonds).The word mining sounds a lot like mineral, and that's no accident because mining is how minerals are removed from the ground. There are several different ways .
Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.
