GCSE CHEMISTRY Extraction of Copper Thermal

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) oxide can be reduced by reaction with carbon.. 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.

Phytomining ScienceDirect

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

Simply put,PHYTOMINING is a form of EXTRACTION. What does it do? It extracts COPPER COMPOUNDS from the ASH of a burnt plant. By burning . the plant, the oxygen is reacting with copper. This makes COPPER OXIDE . The ash which contains the copper compound is then put through ELECTROLYSIS. How do these compounds get into the plant?

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.

Evaluate the Use of Phytomining and Bioleaching in Metal

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.
