The Concentrating Process - Britannia Mine Museum

The process used to separate the minerals is called 'concentrating'. Breaking the chemical bonds and separating the elemental copper from the other mineral components is called 'smelting' and 'refining'. This was done elsewhere as there was never a smelter located at Britannia Beach. In the Mill No. 3, the various stages.

Introduction to Mineral Processing - Chevron Phillips Chemical

Lead and zinc often occur in the same ore. Copper is also present in some ores. Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in.

Gravity Concentration | Gekko

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses. The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental.
