Flotation In Mining Copper And Gold Oxide Ore

Copper Mining and Extraction Sulfide Ores

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

Gold-Copper Ores - ScienceDirect

01.01.2016· Flotation and smelting are currently preferred for copper sulfide ores, but as yet there is no practical alternative to cyanidation for copper oxide ores. Iron–oxide–copper–gold (IOCG) deposits, however, are often amenable to flotation to generate a Cu–Au concentrate, with the recovery improving down through the orebody from the oxide zone to the transition and primary zones.

Effect of pulp potential on the flotation of a

01.08.2005· Surface oxidation of secondary minerals, such as chalcocite, bornite and digenite, present in the Salobo copper ore makes their flotation difficult and requires excessive reagent consumptions. Two possibilities for reducing the collector and fr other additions were investigated. These were sulfidization of the pulp prior toflotation and using nitrogen to replace air in flotation.

FROTH FLOTATION : RECENT TRENDS Flotation of Sulphide Ores

History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for beneficiation of vast variety of sulphide minerals. Due

Copper-Cobalt ores - Danafloat

Copper-Cobalt ores. Various cobalt bearing minerals have economic significance including cobaltite (CoAsS). carrollite (Cu (Co.Ni)2S4), and linnaeite (Co3S4). These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used.

These ores belong to a group of refractory gold ores, where flotation techniques can be used to (a) remove interfering impurities before the hydrometallurgical treatment process of the ore for gold recovery, and (b) to preconcentrate the ore for further pyrometallur­ gical or hydrometallurgical treatment. There are several flotation methods used

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

28.08.2020· In this research, flotation of copper, lead and zinc minerals from a copper oxide–sulfide ore was studied. The identification tests showed that the sample is a mixture of quartz, chalcopyrite, galena, cerussite, hemimorphite and iron oxide minerals with 5.04% CuO, 1.61% PbO, 2.07% ZnO and 56.40% SiO2. The experimental design methodology (RSM) was conducted to investigate the effect of

Iron oxide copper gold ore deposits - Wikipedia

Iron oxide copper gold ore deposits are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million to >4,000 million tonnes of contained ore, and have a grade of between 0.2% and 5% copper, with gold contents ranging from 0.1 to 1.41 grams per tonne. These ore
