Acid leaching of a copper ore by sulphur-oxidizing

Aug 01, 2014· We compared copper extraction from ore 1) by addition of sulphuric acid to leach solution to maintain a pH of 2.0 and 2) by biological formation of sulphuric acid from S o oxidation in the ore bed. In the case of (1), the pH of the recirculating leach solution was adjusted 4 to 5 times weekly to pH 2.0 by addition of 5 M H 2 SO 4.In the case of (2), H 2 SO 4 was added only with the initial

A New Application For Flotation Of Oxidized Copper Ore

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.

Copper processing Ores Britannica

Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.

Copper Ore an overview ScienceDirect Topics

The copper ore production process operation as defined in Section 3.1 is simulated for a period of one year with various failure modes. The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation. More MC simulations can be done while characterising the system.

recoveries from oxidized ores because they can selectively form complexes with some metals (Assis, Montenegro, and Peres, 1996). A further benefit of hydroxamates co-collectors is their ability to improve the PGM flotation recoveries from oxidized ores without reducing the performance of the traditional copper sulphide collectors.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
