Refining with flame is one of the oldest methods of refining metals. Mentioned even in the bible, refining by fire is the preferable method for larger quantities of gold. In ancient times, this form of refining involved a craftsman sitting next to a hot fire with molten gold in a crucible being stirred and skimmed to remove the impurities or dross that rose to the top of the molten metal.

Copper refining is done by the electrolytic process. Its impurities of iron and zinc will dissolve in the copper sulphate solution. And its other impurities of gold or silver or platinum will remain behind. Zone Refining. Zone refining is a special method we use to purify metals. It was the invention of William Pfann.

Precious Metals Refining By Solvent Extraction General If a compound (= solute) is dissolved in a liquid (water) and the solution is brought into contact with a second immiscible liquid (= solvent, maybe a hydrocarbon etc.), then a part of the solute is transferred to the second liquid phase by a force called the chemical potential.

Refining (metallurgy) In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer.

Precious Metals Refining By Solvent Extraction. Metal Extraction As far as solvent extraction of metals or precious metals is concerned an additional chemical, a so-called extractant, is necessary to form a chemical compound (= complex) with the solute and thus make it soluble in the organic phase.

The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.
