GCSE CHEMISTRY Extraction of Copper Thermal

Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1% copper but they are still used because copper is so valuable. 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.

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.

Capital costs at this level of operation were to be US$0.08/lb of copper and operating costs, as shown in Table 2, were estimated at US$0.34/lb of copper. 28 The average ore grade is 0.59% copper and the estimated recovery is 78.2%. The operation was upgraded to 180,000 tons per year before it was completed and to 250,000 tons per year in 2001.

how is copper extracted from a low grade ore of it

1) Copper can be obtained from low grade ore through the process of leaching using acid or bacteria (leaching is a process in which ore is treated with suitable reagent which dissolves ore but not the impurities). 2) Reduction:- Then this solution containing copper is treated with scrap iron or H2 to get the copper.

Phytomining: Trends in Plant Science

Phytomining is the production of a `crop' of a metal by growing high-biomass plants that accumulate high metal concentrations. Some of these plants are natural hyperaccumulators, and in others the property can be induced. Pioneering experiments in this field might lead to a `green' alternative to existing, environmentally destructive, opencast mining practices.
