A new way of extracting copper MIT News Massachusetts

28/06/2017 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 Extraction of Copper Chemistry LibreTexts

21/08/2020 The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (C u F e S 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 ores of copper.

Copper Mining and Production Processes Explained

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis.

purification of copper by electrolysis metal extraction

Finite reserves of copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper ores.

Copper Mining and Extraction Sulfide Ores

Copper is very well suited to being recycled because it can be remelted endlessly with no loss of properties. For example, old copper plumbing pipes, taps and car radiators are a major source of recycled copper. They can all be melted down and made into new products. Even the few grams of copper in your mobile phone is worth recovering.
