In the process, calcium oxide or calcium hydroxide are added as a precipitating agent in incremental steps to cause

More particularly, it relates to an organic solvent extraction process for recovering metals from aqueous solutions in which the metals are present as dissolved divalent metal salts. It is well known to extract metal values from metal bearing materials by hydrometallurgical methods involving leaching with acidic, basic or metal salt solutions.

Smelting is the process of heating ores to release the metals in them. This process separates the impurities from the metal, but also creates air pollution because gases that are created as by

Extraction of Metals. What is Electrolysis?. Electrolysis is the process where an electric current is passed through a liquid that conducts electricity. A liquid will only conduct electricity if it contains ions.. The electrodes are often made from graphite. The liquid that conducts electricity is called the electrolyte.
