A secondary school revision resource for AQA GCSE Chemistry about metals and their uses. Copper can be extracted from these ores by heating them in a furnace, a process called smelting. The copper is then purified using a process
Observe the reaction between iron and copper oxide, mixed and heated strongly. ** Iron The more reactive a metal the more difficult it is to extract from its compounds. Copper Start revising A-level & GCSE with 7 million other students.
Bioleaching is the extraction of metals from their ores through the use of living organisms. .. At the current time, it is more economical to smelt copper ore rather than to use bioleaching, since the concentration of copper in its ore is in general
