مهدی ایران نژاد - Outline of mining

The following outline is provided as an overview of and topical guide to mining: . Mining – extraction of valuable minerals or other geological materials from the earth, usually (but not always) from an ore body, vein or (coal) seam. Any material that cannot be grown from agricultural processes, or created artificially in a laboratory or factory, is usually mined.The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the …

Ore - Graphite

Air is normally used for flotation, but recently nitrogen has been successfully used in flotation for chalcopyrite, molybdenite, and gold (Simmons et al., 1999). Further research will be necessary to determine the potential of this innovation. Unfortunately, the advancement of flotation reagents has been slow. ... Large amounts of gangue solids ...Ore, gangue, ore minerals, gangue minerals In most cases, an ore does not consist entirely of a single ore mineral but it is mixed with other valuable minerals and with unwanted or valueless rocks and minerals. ... The valuable ore minerals are separated from the gangue minerals by froth flotation, gravity concentration, ... Molybdenite: MoS 2 ...

In a process for a selective flotation of a copper-lead-zinc sulfide ore the raw ore is ground and slurried with water and the resulting suspension is aerated with air to adjust a certain oxidation-reduction potential and is subsequently successively conditioned with SO 2, Ca(OH) 2, and collecting and frothing agents, whereafter a flotation of Cu is effected.Fardis Nakhaei, Mehdi Irannajad, "Investigation of Effective Parameters for Molybdenite Recovery from Porphyry Copper Ores in Industrial Flotation Circuit ...

US5439115A - Flotation

The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains.The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have …How much Flotation Depressants is needed. Depressants are generally added to the grinding circuit or conditioner usually before addition of promoting and frothing reagents.They may also be added direct to the flotation cleaner circuit particularly on complex ores when it is difficult to make a clean cut separation or where considerable …
