Leaching Processes
The selection of the equipment to carry out the leaching process must consider the factors that limit the rate of extraction. When the diffusion of the solute through the porous structure of the solid limits the process, the solid particles must be reduced in size to facilitate the diffusion of the solid.

It is also important to separate the occluded leach solution from the final leach residue (it may represent as much as 30% of the total copper dissolved). A countercurrent principle of washing is employed. This method, essentially the same as that described for counter-current leaching, may also be effected on either a continuous or batch basis.
