2013-12-24 In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur. An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.

1996-11-20 Spain, made the early advances in copper explo-ration and mining methods. For example, the Ro-mans found nearly 100 lens-shaped ore bodies in the Rio Tinto copper district. Modern geologists have found only a few additional deposits, and almost all of Rio Tinto’s modern production has been from ore first discovered by the Remans.3

2021-7-20 In the practice, the flotation method, gravity separation method and combined beneficiation method can be used for copper - lead - zinc sulfide ore. Among them, the flotation method has become the main separation method of copper, lead and zinc sulfide ores because of its good separation effect on various complex polymetallic co-biogenic minerals.

The essence of this method consists in the following. Copper-zinc ore is enriched by the scheme of direct selective copper flotation. The ore is ground with the addition of calcium oxide to create an alkaline environment and depression of pyrite, sodium sulphide and zinc sulphate for depression zinc materials.

2018-9-24 Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways. Flotation depends on ...
