The Minataur™ Process (Mintek Alternative Technology for Au Refining) is a novel route for the production of highpurity gold using solvent extraction.
Green Refinement. Because the global issues concerning platinum group elements, radioactive minerals, rare metals, lithium and phosphorus result primarily from a lack of distribution as opposed to a lack of production efficiency, Mission 2016 did not work to improve recovery methods of these resources.
Electrolytic refining process disadvantages, such as inconsistent yields and purity, very slow refining speed, only part recovery per batch, only refines carat gold, very expensive inputs per gram of refining etc., do not arise here.

In gold processing: Refining. The Wohlwill process increases purity to about percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the casting functions as a positively charged electrode,.
Though several different techniques exist, any process used to separate metal from impurities or unwanted material is called refining. In addition to the refining of newly mined gold, mints and other facilities also recycle gold scrap, including jewelry, dental filings and metal found in consumer electronics, by removing impurities.

The ancient process of refining gold has already been described under METALLURGY (which see). Most of the Bible references are to the refining of silver (Proverbs 25:4 Zechariah 13:9 Isaiah 48:10). The silver used by the ancients was probably obtained by smelting .
The invention provides a cathode gold electrolytic refining process. According to the invention, an electrolyte formula is changed, and electrolytic refining is carried out in a hydrochloric acid system with low gold ion solubility (Au<3+> 80120g/L) and low acid (6090g/L) with a titanium motherboard used for replacing a traditional gold starting sheet as a cathode.
Static Glass Refining Plant. Introduction to Aqua Regia The aqua regia refining process is used to refine gold alloys using a combination of acids and chemical products. The aqua regia solution consists of a mixture of hydrochloric acid HCL and nitric acid HNO3. The refining process can be broken down into several steps: Read more...
Bacteria Make Gold The largest single lump of gold ever discovered on our planet was found in Australia. It was the Holterman Nugget, and it was found in Hill End in NSW on 19 October, 1872. The whole nugget weighed kg, and contained kg of pure gold. (Strictly speaking, the Holterman Nugget was not really a nugget,...
The process has the advantage of being quick and is widely used for primary refining of gold doré from the mines. Considerable technical skills are required for this process, and there are a number of health and safety implications in the use of chlorine gas.
