Explanation: Mineral Dressing is an important method of beneficiation. This technique helps to remove substantial portions of gangue and upgrade the raw material. This does not destroy the physical and chemical properties of the minerals. When the mineral dressing is applied to ores it is known as Ore Dressing.

The content of REO in raw ores is low, so metallurgical processes cannot be carried out directly. According to the differences in specific gravity, magnetism, conductivity and floatability between RE ores and associated minerals, mineral dressing processes are adopted to produce high-grade RE minerals.

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 ...
