GCSE CHEMISTRY - Extraction of Copper - Thermal ...

Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated. Thermal decomposition is an endothermic ...

How is bioleaching used to extract copper?

Phytomining - How It works Select plants will absorb copper compounds through their roots, and the compounds become concentrated in the plant. When the plants are burned, the ash that is produced contains these copper compounds. Then, the copper will be extracted from the leachate by electrolysis or scrap iron. How do you extract copper? Copper can be extracted from its ore by: Underground ...

Copper is one such metal where phytomining has been used in its extraction. In the process of phytomining plants are grown on top of the low grade ores. The plants absorb the copper(II) ions through their roots.

Evaluate the Use of Phytomining and Bioleaching in

Like phytomining, bioleaching is a useful method for extracting metals from low-grade ores. This is particularly important for copper, where high-grade ores are increasingly rare. It also uses less energy than smelting. However, some of the chemicals produced in the process are harmful, and the process is relatively slow and expensive.

Bioleaching - Wikipedia

Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt
