Gold refining by solvent extraction—the Minataur™ Process

The Minataur™ Process (Mintek Alternative Technology for Au Refining) is a novel route for the production of high-purity gold using solvent extraction. Following the successful demonstration of the process on a pilot-plant scale, a full-scale 24 t/a production plant has been commissioned at Harmony Gold Mine in Virginia, Free State.

Solvent Extraction and Stripping of Gold(III) from

employed as a reagent for gold(III) from acidic chloride media in some commercial plants [14,15]. In the process operated in Inco’s Acton precious metal refinery, gold is recovered by solvent extraction with undiluted DBC after the recovery of ruthenium and osmium by distillation from the liquor from an HCl total leach of anode slimes of copper or nickel [15]. In this step, gold is highly

US8926730B2 Method for recovering gold by solvent

The invention relates to a method for recovering gold by solvent extraction from an acidic chloride-containing aqueous solution or from slurry containing gold-bearing solids using a diester-based reagent that is poorly soluble in water as organic extraction solution. In accordance with the method, gold is extracted extremely effectively, but other precious metals and many other metals quite

Solvent extraction reagents for gold recovery from

The substituted guanidines is the most recent gold solvent extraction system studied, and the experimental results indicate that excellent extractions can be achieved at pH 11 and stripping above pH 13 provided that an appropriate alcohol is used in the diluent (carrier). The suitability of the substituted guanidine solvent extraction system for treating dilute leach solutions has been demonstrated in pilot

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

Base Oil Solvent Extraction Refining Plant VMETS

Solvent extraction is the term used for the removal of most of the aromatics and undesirable constituents of oil distillates by liquid extraction. Commonly used solvents contain phenol, furfural and sulphur dioxide. The resulting base stocks are raffinates (referred to as neutral oils) and an extract that is rich in aromatic content, which is highly sought after as a process oil or fuel oil. Dewaxing. After solvent extraction, the

Solvent extraction: the coordination chemistry behind

Solvent extraction: Also, hydrometallurgical plants are smaller than those for pyrometallurgical processing so can be located close to the mining operations, and are often environmentally favoured due to lack of SO 2 emission that is frequently associated with pyrometallurgy. The technology is well suited to metal recovery from low grade, mixed metal, ores and can be adapted to the
