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 ...
Separating Metals from Mud
The ore which we dig out of the ground is a combination of rock and the useful minerals we want. The problem is the proportion of the useful minerals can be only 1 or 2 percent, and that's still worth extracting. ... they are copper iron sulphide, or copper sulphide, something like a chalcopyrite as it's called versus an oxide mineral which is ...
