An Introduction to the Chemistry of Metal Extraction
As you will see if you read the page about titanium extraction, this is the only way of producing high purity metal. TiCl4 + 4Na → Ti + 4NaCl T i C l 4 + 4 N a → T i + 4 N a C l. The more reactive metal sodium releases electrons easily as it forms its ions: 4Na → 4Na+ + 4e− 4 N a → 4 N a + + 4 e −. These electrons are used to reduce ...
The Chemistry of the Extraction of Gold
THE CHEMISTRY OF THE EXTRACTION OF GOLD Cu(CN);- and Cu(CN)!-. The insoluble gold cyanide compound AuCN precipitates from acidic solutions of aurocyanide ions as follows: Au(CN); + H+ = AuCN + HCN. (15.2) This reaction takes place readily in strongly acidic solution and slowly in weak acid solutions (pH 2 to 3).
