Jul 09, 2019 · (7) Arsenic sulfide copper ore The ore has a high content of arsenic, which is mainly in the form of arsenopyrite. Flotation process to solve the problem of copper and arsenic separation, reduce the arsenic content in the copper concentrate as much as possible.
Copper Sulfide Flotation - Mineral Processing & Metallurgy
Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite. The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values. The ore, ranging from 60-65% silica, with pyrite, arsenopyrite, and calcite with 3 to 4% copper. This flowsheet, though simple, is adequate for …
Sulfide Ores - an overview | ScienceDirect Topics
Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a …
(PDF) Flotation of an Oxidized Copper Sulfide Ore
Flotation of an Oxidized Copper Sulfide Ore at 16 g/Mg KAX, pH 9, and 30% solids (Fi gure 3), one can see that t he copper recovery increases sharply with 15+ million members 118+ million...
Flotation of Copper Sulfide Ores - PDF Free Download
12. Flotation of Copper Sulfide Ores This reaction is characteristic of the secondary zones of formation of a copper ore body. Chalcosine may partially or completely transform into malachite, azurite, chalcocite, etc. and therefore in many porphyry deposits, zones of oxide copper are present.
Sulphide Flotation - an overview | ScienceDirect Topics
In most flotation plants, sulfur and silver on gold grains (in all likelihood in the form of silver sulfide) promoted gold flotation. Copper must be assisting gold flotation as deciphered from the superior floatability of auricupride [Cu 3 Au] and tetra-auricupride [AuCu] relative to native gold. At the Kemess flotation plant depending on the ore type (milled in separate campaigns), the role of some surface …
Flotation of a copper sulphide ore from Okiep using thiol ...
Thiol collectors are used in the froth flotation of copper sulphide ores. The xanthates, dithio-phosphates and dithiocarbamates are classes of thiol collectors that each form different surface products on different copper sulphide minerals. It has been shown that the use of mixtures of thiol collectors can have benefits over the
Copper Mining and Extraction Sulfide Ores
These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their stone formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to be separated.
Copper Mining and Processing: Processing of Copper Ores ...
Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.
(PDF) A Review of the Flotation of Copper Minerals
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 hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines)...
Copper Flotation - Elmhurst College
The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of stone mills) to make bubbles, an alcohol to strengthen the bubbles, and a collector stone called potassium amyl xanthate (or the potassium …
Treatment of Mixed Sulfide Oxide Ores of Copper
Flotation is generally successful for the sulfide minerals and flotation after filming with sulfide seems to work in many cases on the pure carbonate minerals. Callow has given an extensive report on the results of “ sulfidizing ” flotation on the ores of the Magma mine.
Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...
the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals from a nickel-copper sulphide ore. 2. Materials and …
Copper Ore Types: Sulfides vs. Oxides | An Investors ...
Supergene copper ores rich in sulfides may be concentrated using froth flotation. Types of copper ore: More information
Sulphide Ores - Clariant Ltd.
Our alternatives have proven performance in the flotation of copper ores, polymetalic ores and gold associated to sulfides. Polymetalics Ores Clariant Mining Solutions HOSTAFLOT® collectors are formulated to achieve the best possible recovery and selectivity when needed.
Copper Mining and Extraction: Oxide Ores
Pyroprocessing Sulfide Ores Provides Acid for Leaching. The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting …
