Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ

Another example relating to treatment of intrusion water from a copper mine is shown below. This example shows the reduction of contaminants from dam water entering the mines water treatment plant. The water was first treated by MFRO and the concentrate was subsequently treated by a Disc TubeTM RO system with the following results:

In this interview, Dor#233; Copper Minings president and CEO Ernest Mast provides an overview of the companys investment value proposition, describes why the company is undervalued and explains the plans
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
Mining for Copper Bearing Ore. There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment. The major producers of copper ore are Chile, USA and Australia, the vast majority of the ore coming from open pit mining. In open pit mining the layers of soil
