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 orewater pulp and second collecting the copper minerals at the top of the pulp as a briefly stable mineralwaterair froth.
Nevada Copper (TSX NCU) said Tuesday that it completed the underground materials handling system of the main shaft which will significantly increase hoisting rates from currently 1000 tpd to ultimately 5000 tpd once commissioning and rampup are completed. The company said that the materials handling system represents a significant milestone in the construction of its underground
The first step mineral processing is to liberate the copper minerals and remove waste constituentssuch as alumina limestone pyrite and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent copper. The second step involving either smelting or leaching removes a large proportion of

A worked example was presented for a Copper/Gold/Silver deposit. The process used to express the Equivalent Grade in terms of any of the three major metals of interest was explained
The copper ore usually contains a large amount of dirt clay and a variety of noncopper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is
The process used to treat sulfide copper ores begins at the mine site where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined first physically by froth flotation then chemically by smelting and finally electrolytic refining.
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 directsmelting ores are produced the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores in four basic steps 1) froth flotation 2) thickening 3) smelting and 4) electrolysis.
