The influence of microwave pre-treatment of the leach

01/07/2011· ► Microwave pre-treatment induces macro and micro fracturing in ore particles. ► Fracturing increases the internal surface area of particle. ► Increasing the surface area leads to increase in copper yield during leaching. ► Wetting agents reduce the hydrophobicity of the surface and further increase Cu yield.

The influence of microwave pre-treatment of the leach

01/07/2011· With microwave pre-treatment, the porosity of the ore particles is increased by inducing macro- and micro-fracturing in the particle, the result being that there is a substantial increase in the internal surface area of the ore particles. A further increase in copper yield can be achieved by using the ability of a wetting agent to adsorb on the surface of the particles. In cases where the

Heap leaching Wikipedia

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 re-separate 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

Copper Geoscience Australia

At some Australian mines, the copper is leached from the ore to produce a copper-rich solution which is later treated to recover the copper metal. The ore is first broken and set out on leach pads where it is dissolved by a sulfuric acid solution to leach out the copper. The copper-rich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex. This is
