Rule investigated an ore containing 1.77% total copper (1.67% and 0.1% as copper oxide and copper sulphide, respectively). Mineralogically, the ore contained 80% of the minerals atacamite and paracamite. The ore sample was ground to 97%, passing 150 μm, and all flotation experiments were performed at pH 8.7.

productivity for sulphide concentrates by more than 50%. Change in the direct crude copper production process could solve these problems, but the high copper concentration in the slag (2-1 1%) is a major obstacle. It could be removed by deep reduction of liquid slags using solid carbon. Such a process can be realized in a coke filter furnace.
A review of zinc oxide mineral beneficiation using flotation method. 31 Sulfidizing agent The process of sulfidization is converting the surface of the oxide mineral such as MCO 3 (M: metal element) into a sulfide surface This process includes the dissolution of Na 2 S in which HS − and S 2 − ions form in aqueous suspension, with adsorption of HS − and S 2 …
There are two main types of copper ore that are of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, but they are processed in different ways. Copper ...
of sulfide copper-nickel, copper-pyrite deposits, and ores of copper sandstones and slates are primarily pro-cessed abroad. The amount of copper in copper sand-stones and slates varies from 1 to 6%, in sulfide cop-per-nickel ores from 1.1 to 4.9%, in copper-pyrite ores from 0.1 to 3%, and in copper-porphyry ores from 0.4 to 1.2%.
The most viable route to recover copper from sulphide phase is flotation using chemical reagents which previous researchers such as [2, 12, 27] further elaborates on using a two-stage flotation process to recover copper and get 80–87% with iron being further concentrated by a specified technique of molten slag added complex additives. …

Copper is extracted by the auto reduction of copper oxide by copper sulphide.II. Aluminium cannot be obtained by chemical reduction due to its strong affinity for oxygen.III. In electrometallurgy of Al, graphite is used as cathode to avoid reoxidation of Al into Al2O3 by preventing formation of O2 .IV. Sulphide ores of copper are difficult to ...
Abstract In the present work, the leaching behavior of copper from an oxide/sulfide ore was assessed in two work phases including process optimization and kinetics modeling. In the first phase, the individual and synergistic impacts of the influential parameters such as sulfuric acid concentration, liquid/solid ratio, pulp mixing rate, temperature, and contact …
The treatment of copper sulfide minerals containing a high percentage of oxide copper causes problems in the concentration process, decreasing the copper content. In order to increase the efficiency of the concentration process, it is necessary to treat the copper oxide component by leaching the grinded ore prior to the flotation, or by ...
In the copper(I) sulfide, the copper is +1 and the sulfur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. ... Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such ...
Some Cu(II) was reduced to Cu(I) during sulfidation, coupled with sulfide oxidation to sulfate, resulting in the formation of small amounts of several copper sulfate hydroxide species as well. The extent of sulfidation depends on the sulfide to CuO molar concentration ratio used.
For mixed oxide-sulphide ores, up to 80% of the copper and 60% of the cobalt is recovered in the sulphide concentrate while for the oxide concentrate, only 60% of the copper and 40% of the cobalt are usually recovered (Crundwell et al., 2011). With mixed oxide-sulphide ores, it is accepted practice to concentrate sulphide and oxide …
