RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.

Paper looks at effect of pH on flotation of different sulphide mineralsEffect of reagents and minerals on froth electrical The effect of three chemical reagents used in froth flotation, and also the effect of pH, was studied: dosage of Dowfroth (Test 1), xanthate (Test 2), zinc sulphate (Test 3) and pH (Test 4). Each test consists of three step tests, where the value of variable in question was changed while other values were kept at their base levels. Each test was
Combined Effect of Operating Parameters on Separation 9/24/2018· The Effect of Experimental Parameters on Grade, Recovery, and Separation Efficiency. Considering the grade-time graph in Fig. 2a, as the flotation time increases, the concentrate grade (% Cu) decreases with a similar trend for all tests. Initially, as a result of the flotation of a large portion of the valuable mineral, the concentrate grade is high.
The Adsorption of Cu Species onto Pyrite Surface and Its The adsorption of Cu species onto pyrite surface and its effect on flotation were investigated by using microflotation tests, first-principle calculations, and XPS surface analysis. The results indicated that the flotation of pyrite appears to be activated with CuSO4 only at alkaline pH, while being depressed at acidic and neutral pH. The adsorption of copper ions on pyrite surface
Effect of alkalinity of a pulp on selective flotation of We study the effect of one of the main parameters of flotation ore-dressing, specifically, alkalinity of the pulp, on the selective flotation of sulfide and oxide minerals of copper from the Udokan deposition ores (Chita oblast). It is found that the optimum values are pH = 9 for sulfide minerals of copper and pH = 10 for the oxide ones. A supply of lime at the stage of pounding and sodium
Effect of Desliming on Flotation Response of Kansanshi
The Kansanshi mixed copper sulfide-oxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was The effect of underground mine water on performance of the The nature of the effect of the underground water at Mufulira, particularly the sensitivity of the flotation to the pH at which the milling was conducted, characterized galvanic interaction. A large-scale plant situation is presented in which the desired electro-chemical response in the flotation was achieved, by a deliberate manipulation of The interaction of pH modifiers with kaolinite in copper The objective of this study was to assess the effect of lime and soda ash as pH modifiers on the flotation of a copper-gold ore mixed with kaolinite at different concentrations. For the flotation experiments air flow rate, impeller speed, flotation time and other flotation reagents were kept constant, and the flotation outcomes were explained by the rheology behavior of the slurries and the EFFECT OF GRINDING CHEMISTRY ON THE SULPHIDISATION The recovery of copper by sulphidisation and flotation from a mixed ore has been studied in detail in this thesis. Particular focus was given to the effect of pulp chemistry on the sulphidisation mechanism and subsequent flotation response of oxidised sulphide minerals, both
