Gold refining by solvent extraction—the Minataur™ Process
During the past year, two pilot-plant campaigns were carried out in which 5 kg/d of high-purity gold was produced from silver- refining anode slime and from gold- electrowinning cathode sludge. Following the success of these trials, the first full-scale gold refinery to use this process has recently been commissioned.

Gold Refining Process | PDF
The Minataur leach solvent extraction precipitation process developed by Mintek is an alternative to other gold refining processes that consists of three steps: leaching gold-containing material in an oxidative solution, selectively extracting the gold using solvent extraction and stripping it into an aqueous solution, and finally reducing the solution to solid gold. This process uses an ...

Refining of Gold- and Silver-Bearing Doré
The Minataur™ process, developed at Mintek in South Africa and operated by Harmony Gold for several years (Sole et al., 1998, Bower and Bazhko, 2015), was designed to directly leach gold sludge produced in the electrowinning step of the cyanide extraction circuit at the mine site. The sludges were dissolved using HCl and chlorine.

MINATAUR : the Mintek alternative technology to gold …
In addition to refining gold to high purity, if an appreciable amount of silver is present in the feed material it is also refined to 99.99 per cent purity. The major advantage that the Minataur� technology has over other gold refining processes is the relatively low gold lock-up and reduced operating costs.
