If you are extracting copper from a 1% ore grade, heap leaching will require 225kWh/ton-Cu of energy, while a subsequent electro-winning step might require 500kWh/ton. By contrast, smelting might require 6,000 kWh/ton. This is the alchemy miracle of hydrometallurgical processing, and why we consider heap leaching to be an efficiency technology.

2.2.1. Solid-Liquid Dissolution. A key aspect of the heap leach process is the dissolution of metals from the minerals of interest. In this work, the rate of dissolution is calculated using a shrinking core model to combine the effects of diffusion through the rock matrix and the kinetic reaction rates.

Leaching processes can be defined as the selective removal and/or extraction of metallic values from a mineral, causing a suitable solvent of the leaching agent to percolate into and through a mass of heap or mineral containing the metallic values [ 1 ]. Leaching is of great importance in the field of metallurgy since it is frequently used in ...
