Flotation : The flotation process collects the sulfur-bearing portions of the ore, which contains the valuable metal. In Flotation process many other chemicals are also added to help concentrate the minerals. Lead is separated from the rock and the mineral e.g. copper. Zinc at the end of the flotation process.

The collectors currently used in the flotation process of copper ore, in addition to the more traditional collectors for sulfide ore, many other types of collectors, such as LP-01, BK-901, and Y-89 are also selected. However, in the flotation process of copper ore, several collectors may affect the results or even interfere with each other.

In this process, the ore initially is crushed to about 1.9 centimetres (0.75 inch), combined with water, and ground to less than 0.1 millimetre in a ball mill. The finely ground particles and water form a slurry that flows from the mill to flotation cells or tanks, where, in the presence of selected chemical reagents that create a suspension of ...

The history of iron ore flotation started with direct flotation of iron oxides using anionic collectors such as petroleum sulphonate, fatty acids and hydroxamates. In 1950s, the direct flotation route was integrated in plants, including Humboldt Mine (USA, 1954), Republic Mines, (USA, 1956), and Anshan Iron & Steel Corporation, (China, 1958).

Flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.
