In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper bearing minerals from it. To be applicable to this process, the ores must contain copper minerals in sulfide form
Having a few dump trucks or conveyors misrouting ore in large, integrated copper stockpile leach/heap leach/concentrator operations with molybdenum by products may result inpounded losses in the multimillion dollar range. Pushing tonnage tonnage farming has its place, but, without concurrent good ore characterisation, it can be a high risk to optimal metallurgy. For geo
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
The first plant practice of TL leaching for copper was in 1980 at Sociadad Minero Puduhuel SMP22. SMP obtained high copper recovery from both the oxide and sulphuric portions of their ore, low solube silica in the pregnant leach liquor, and an overall water/acid balance to give a zero discharge plant.
Conventional crushing and grinding plants are safe and conservative. The ore can be tested by proven techniques and crushers and mills selected with assurance that they will meet performance requirements.

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 todays compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, its roasted, which helps to convert sulfides to oxides.
