Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

· Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return.This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...
Flotation is a widely used dressing method for the processing of gold ores in gold ore dressing plants. It is commonly used in the treatment of sulfide mineral ores of high flotation property.
Usually there are: feeders, primary and secondary crushers, shakers, ball mills, classifiers, chutes, magnetic or flotation machines, dryers. Machines can be increased or decreased as required. 3. What is the final mineral concentration? This depends on the the ore grade. The final concentration of gold ore can reach 80-90%.
· Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (3.63% iron) was considered as the sum of the energy for the ore-handling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth''s crust; surface mining is assumed.

· In a study, flotation recovery of copper and nickel ore was increased from 74% to 84% and from 79% to 86%, respectively (Viljoen et al., 2001). Test studies showed that high Zn recoveries could be obtained at efficient energy use (van Drunick et al., 2010).
· Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.
· The gold content in the placer gold mine is extremely low, and it is known as the gold panning by beneficiate the placer gold through various energy-efficient placer gold equipment. Among various gold extraction methods, the gravity separator method is energy-saving, efficient, environmentally friendly, and is suitable for placer gold ore …

The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].
