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 ...

Recovery of Molybdenum from Oxidized Ore

Table of ContentsLeachingCharcoal StrippingEvaporation and Crystallization The Climax ore body is basically a sulfide deposit capped by an oxidized zone. No secondary enrichment is present. As oxidation occurred the molybdenum from the molybdenite immediately reprecipitated in place with the iron minerals. The molybdenum-bearing minerals in the oxidized zone were identified as geothite ...

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.

Recovery of Copper by Solution Mining Methods

Recovery of Copper by Solution Mining Methods 3 Supplementing production from conventional heap leach operation, the in-place rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper. The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene
