I learned quite a bit about the mining process and its challenges from Emerson's Alena Johnson excellent Mining Engineering magazine article, Improved flow measurement and control are key to efficiency. Alena opens describing the heap leaching process for copper:
Acidic (low pH) water will leach more copper than more basic (high pH) water will. Soft water is likely to contain more copper than hard water because it doesn't contain the minerals that build up a protective layer on the interior of pipes, preventing copper from leaching.
by neutralizing the acid leach liquor or by leaching oxide copper with ammonia, but neither solution was economical. a molecule that extracted copper well from typical dump leach liquors (pH ~1.8) had to be built. The reagent LIX 64, containing the ketoxime LIX Copper recovery using leach/solvent extraction/electrowinning technology:
In situ leaching offers a potentially attractive way to extract copper from the subsurface without costly fragmentation and processing. Applicability of in situ leaching is limited to deposits where sufficient permeability exists and where the copper and gangue mineralogy is amenable to leaching.

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
Oct 25, 2015 · The Bagdad mine is a large copper mine and represents one of the largest copper reserves in the United States and in the world, having estimated reserves of 873.6 million tonnes of ore grading 0.36% copper. Bagdad mine is home to the world's first commercial-scale concentrate leach processing facility (2003) and one of the longest.
Heap leaching mining was developed as a mineral processing low-grade metal that is more efficient and minimal cost. Compared with conventional cyanidation process of the mineral leaching process with stirred tank Heap leaching has several advantages in the form of designs that use a very simple, operating costs are also minimal, and in requiring less investment, because the heap leaching .
PREPARATION OF THE COPPER ORE. This study is limited in general to percolation leaching as it is the most widely used method to give proper contact of solvent with the ore to effect extraction of the copper. One of the important factors in percolation leaching is the size reduction necessary for copper recovery within reasonable time limits.

Whatever your goal, if you are trying to build a profitable mining operation you should see if you have what you need to utilize in situ copper leaching to get you there. It has proven itself in operation, not just in the lab or in pilot tests. It has proven that it can produce copper in the lowest quartile of .
been ground to a size suitable for leaching, and hence the cost/of mining and crushing could be done away with. This would bring the cost of leaching the copper to simply the cost of extracting the copper from the ore, and refining it. The material could be shoveled from the dump by a
The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine.
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 it can be used on ores with as little as 0.1% copper - for this reason, leaching extraction is growing in importance.
