SOLUBLE METAL RECOVERY IMPROVEMENT USING .

Counter Current Decantation (CCD) thickener circuits are used to recover soluble metal as pregnant liquor solution from ore leach residue. The basis of CCD operation is to concentrate suspended solids thereby minimizing liquor content in underflow slurry that flow in one direction. Then the

Current Energy Requirements in the Copper Producing ...

Dec 20, 2013· An analysis of energy usage in the production of refined cathode copper was made from mining ore to cathode copper. In mining copper ore the greatest energy consumers are ore hauling and blasting. Another important factor is the "recovery efficiency" of the metallurgical processes used to extract the copper.

Innovations: Introduction to Copper: Mining Extraction

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.

Hydrometallurgy an overview | ScienceDirect Topics

Once the ore has been leached, it is cooled through several flash tanks to recover as much of the energy as possible. The cooled slurry is then preneutralized and sent to a countercurrent decantation circuit, where the solids and liquids are separated. The impure leach solution is further neutralized to remove more contaminants.

Merrill–Crowe process Wikipedia

The solution is separated from the ore by methods such as filtration ( horizontal leaf type clarifiers) and counter current decantation (CCD). Afterwards a very clear solution is achieved by using precoated filters applying diatomaceous earth. Oxygen is then removed by passing the solution through a vacuum deaeration column.

Copper mining. From ore to copper.

The ore is treated with dilute sulphuric acid. This trickles slowly through the ore dissolving copper to form copper sulphate. The copper is recovered by electrolytic refining. Advantages of this process are: much less energy is use than in traditional mining no waste gases are given off
