Liquid–liquid extraction

Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Leaching (chemistry)

Leaching is the process of a solute becoming detached or extracted from its carrier substance by way of a solvent.. Leaching is a naturally occurring process which scientists have adapted for a variety of applications with a variety of methods. Specific extraction methods depend on the soluble characteristics relative to the sorbent material such as concentration, distribution, nature, and size.

Mineral Processing

Mineral Processing includes recovery operations at a mine site and the associated processing plant. The processing operations involve the extraction of metal ores and minerals from the mined rock.

Mineral Processing Solutions

Zinc calcine is the soluble zinc form which is the primary feed for the leaching plant. After leaching, the acid leach slurry is thickened and dewatered to recover residues which go to the lead smelter for further processing. After neutralization, clear zinc sulfate solution flows from thickeners to the zinc dust purification circuit.
