Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or...
Pneumatic flotation is already fully established in a number of places and the results in comparison with the other and older schemes fully justify the opinion of your correspondent that it constitutes the most distinct advance in flotation in recent years. The first pneumatic-flotation plant in this country was erected by me in February 1914 for the National Copper
Ore Concentration by Froth Flotation Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation.
Flotation of Copper oxide ore. The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the
Chalcopyrite was the major copper mineral in the HQ ore, constituting 3.9 %, but only 1.0 % of the LQ ore. LQ ore was dominated by chrysocolla, which constituted 3.8 % of the ore. The treatment of HQ ore with 30 g/t SIBX has shown that up to 90 % of the copper can be recovered from HQ ore.
BULK FLOTATION OF COMPLEX COPPER ORE
Flotation is the most adoptable unit process for copper beneficiation. The process of flotation is extremely challenging due to interdependence of various operating parameters. Current study focused on the selection of reagent system based on the complex mineralogy of
1/8/2018 In this study the flotation of a copper ore in the presence of talc and muscovite was studied. It was found that talc can affect copper flotation mainly via froth phase. The copper grade and recovery were affected in the presence of only 7% talc. On the other hand, muscovite influenced the pulp phase via affecting the pulp rheology.
Results of flotation tests were unsuccessful in terms of both recovery and grade of concentrate product. The highest copper recovery of concentrate was found as 61.35% with 8.69% copper content. The concentrate with highest copper grade of 34.65% was obtained with only 26.98% copper recovery.
