In this study, flotation of oxidised ores rich in copper and cobalt from Mupine deposit in the Democratic Republic of Congo had been investigated. This ore contains 4.85% copper, 0.16% cobalt. The recovery of copper and cobalt was performed using flotation to increase the concentration of copper and cobalt.
Used as the collector for the flotation of non-ferrous metal mineral which need strong collector but no selectivity. It is a good collector for the flotation of oxidized sulfide ore or copper oxide and zinc oxide (vulcanized by the sulfiding agent）as well as copper-nickel sulfide ores …
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a bench-scale testing regime. The processing of the test ore was problematic due to a mineral assemblage that caused prevalent slime generation.
base metals industry and is aimed at optimising the recovery of copper in the flotation circuit. 1. Background It was documented by Morse1 in 1922 that many of the largest copper deposits contain both sulphide and oxidised copper minerals. Ninety years later ore complexity is still challenging metallurgists when attempting plant-specific
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. It was established that recovery of copper and cobalt ...
To improve the recovery of copper from refractory copper oxidized ore by sulfidization-flotation process. The result determined the optimal flotation process parameters of refractory copper oxidized ore, and the better quota selecting separately obtained by a large number of research. The copper concentrate grade reaches 10.85%, the recovery reaches 57.41%.
W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001. 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral ...
The industry is well aware of the difficulty in treating copper ores in the presence of clay minerals. In this study, the effect of bentonite on the flotation of chalcopyrite (a primary copper sulfide mineral) and chalcocite (a secondary copper sulfide mineral) was investigated in terms of surface coating.
In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate. The ease of individual mineral flotability ... about 40 stph high grade copper ore. The primary rougher
Jul 09, 2019· 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

A New Application For Flotation Of Oxidized Copper Ore Recep Ziyadanogullari, Firat Aydin* Dicle University, Faculty of Science and Art, Chemistry Department, 21280, Diyarbakır-TURKEY Abstract: In this study, the flotation of oxidized copper ore obtained from Ergani Copper
Flotation of a copper sulphide ore from Okiep using thiol collectors and their mixtures The collectors sodium ethyl xanthate (C2-X), sodium diethyl dithiophosphate (di-C2-DTP) and sodium diethyl
Oxidised copper ore vs Copper oxide ore. Oxidised copper ore bodies are copper ore bodies which are oxidised in a geological sense. Not a chemical sense. ie; they are products of oxidation of reduced copper minerals (sulphides) to "oxide" minerals such as carbonates, within the regolith. This is still reduced in a chemical sense, although I may ...
For refractory oxidised copper ores of Huidong Sichuan province, studing the different depressants on the influence of oxidised copper ores flotation behavior. The results showed that: the depressanting effect of the combination of sodium hexametaphosphate primarily is better. When the dosage of the combination of sodium hexametaphosphate and sodium humate reagent is 300 g/t, ratio is 2:1,the ...
The copper ions activated pyrite at a pulp potential lower than +400 mV SHE. Abstract In previous study, the selective separation of enargite from complex ore samples in a batch flotation system under controlled pulp potential was investigated (Tayebi-Khorami et al., 2017b).
While good results are often obtained with ethyl xanthate alone as a promoter, the addition of a small quantity of one of the higher xanthates is frequently found to improve the recovery of those minerals that are not readily floated by the lower xanthate, especially those that are tarnished or oxidized…
Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper.
The oxide orebodies, in which the copper is present about half as sulfide and half as oxidized minerals, and where the recovery to be expected is 25 or 30 lb. per ton of ore, might well be treated first by the method used at New Cornelia, to recover the oxide copper, then reground and sent through the regular flotation operation.
Oxidized copper orebodies may be treated in several ways. ... Supergene copper ores rich in sulfides may be concentrated using froth flotation. Types of copper ore: More information.
flotation, obtaining conditional copper and zinc concentrates. Despite several of studies that have been done related to this issue, effective selective flotation of tennantite ores is still the subject to investigation. 4.2. Effect of particle size distribution on copper recovery Chalcopyrite and tennantite ore samples were received from
Copper-making stage – the remaining sulfur is oxidized keeping the oxidation of copper to a minimum. [8] Cu 2 S ( white metal ) + O 2 = 2 Cu ( blister ) + SO 2 As previously noted, three steps of copper extraction (roasting, smelting, and converting) can also be carried out continuously in for example the Mitsubishi process.
