Copper Mining and Extraction: Sulfide Ores

Metals are often found as compounds in ores. An ore is a rock or mineral that has enough metal in it to make it worth extracting. Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon.

Occurrence of Metals: Metal Ores, Methods of Extraction ...

For instance, common metals like iron are smelted using carbon as a reducing agent. Few metals, such as aluminum and sodium, don't have a commercially practical reducing agent and are extracted using electrolysis instead. Sulfide ores are not reduced directly to the metal but are roasted in air to convert them to oxides. Gangue or Matrix

SULFIDE MINING - Minnesota Center for Environmental ...

Sulfide mining, unfortunately, poses several significant environmental risks. The most significant one is the threat to water quality. When sulfide ores are exposed to air and water, the result is sulfuric acid, which causes the leaching of potentially toxic heavy metals and the release of sulfates that contribute to the methylation of mercury.

Nickel: smelting, producing-Metalpedia

The acid pressure leach solution is treated using hydrogen sulphide to produce a high grade sulphide containing at least 50% nickel. This mixed sulphide is then pressure leached to give a high purity concentrated nickel-cobalt solution, suitable for solvent extraction to separate the valuable metals.

Roasting (metallurgy) - Wikipedia

Roasting is a process of heating of sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
