The purification of such alluvial gold alloys is a simple matter. The high specific gravity of the metal allows of separation from most admixed materials by some process of elutriation, or water concentration, or, in arid regions, by dry blowing. The coarser particles are readily picked out, but the finer are usually admixed with heavy sands, consisting of crushed zircons, garnets, cassiterite, wolfram, titanite, …

Theprocessis simple and easy. By using our REFINEIT system, all the user has to do is melt thegoldin an ingot, submerge thegoldin thegold refining equipmentwe provide, then wait. The next day, pure, 24-karatgoldwill be waiting!Gold Refining Systemsnot only makes thegold refining, reclaimingprocesseasy, but also clean and safe.
The Millerprocessuses gaseous chlorine to extract impurities whengoldis at melting point; impurities separate into a layer on the surface of the moltenpurified gold. TheMiller processis rapid and simple, but it producesgoldof only about 99.5 percent purity. TheWohlwill processincreases purity to about 99.99 percent by electrolysis.

Gold, as it occurs in Nature, is never pure. Occasionally the amount of alloying metal is less than 1%, hut as a general rule it is greater; the commonest alloy, in fact, the invariable one, being composed ofgold…
The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting. By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts …

Removing thegold-bearing rock from the ground is just the first step. To isolate puregold, mining companies use a complex extractionprocess. The first step in thisprocessis breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
Goldis purified by means of a smeltingprocess, which utilizes pressure, high heat and chemicals to accomplish the task. Like any metal that appears naturally in the earth, there are impurities that must be removed. Removing minerals and other impurities allowsgoldto be used in its purest form, which is …
The final stage ofgoldproduction -- refining-- involves removing impurities that remain after the smeltingprocess.Refining companies receive doré bars, as well as scrapgold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the puregoldfrom other precious and less precious metals. A sample is then taken to a lab for tests, or ...
