4.1.6.2: The Extraction of Copper - Chemistry LibreTexts

2023年1月14日 Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (\(CuFeS_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest

Innovations: Introduction to Copper: Mining Extraction

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

A new way of extracting copper - MIT News

2017年6月28日 Most current copper extraction processes burn sulfide minerals in air, which produces sulfur dioxide, a harmful air pollutant that has to be captured and reprocessed, but the new method produces elemental sulfur, which can be safely reused, for example, in fertilizers. The researchers also used electrolysis to produce rhenium and

A Guide to the Extraction of Copper - ThePipingMart Blog

2022年12月19日 Extraction of copper from its natural form can be a tricky process. One of the equations that is used to describe copper extraction is Cu2S+2Cu2O→6Cu+So2. This equation illustrates how copper can be extracted from its ore by combining it with oxygen and sulfur. The reaction yields six atoms of pure copper and sulfur dioxide as a byproduct.
