gold processing from crushing to bar

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.

Gold processing, preparation of the ore for use in various products.. For thousands of years the wordgoldhas connoted something of beauty or value. These images are derived from two properties ofgold, its colour and its chemical stability.The colour ofgoldis due to the electronic structure of thegoldatom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...

Metallurgicalprocessingof metalliferous ores in general andgoldores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and; Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are …

Goldcan be concentrated and recovered by applying differentgoldrefiningprocessmethods and the final product has variable quality. In this way, it is necessary to have a better marketable product so that the incomes can be improved. Then, we have two smelt and cast thegoldintobarscalled bullion or Dore.

The molten gold has higher density and so it sinks to the bottom. As the smelts ore cools, the slag remains on the top and the pure gold can be removed from under the slag. The small gold button can then be put in the furnace, melted and transferred into bar mold to form gold molds.

In some refineries large crucibles are used, and 3,000 or 4,000 ozs. of metal are refined at once. In this case, several ingot moulds are filled successively from one pot, usually by means of an iron ladle, the weight of thegold barsmanufactured being usually either 200 or 400 ozs. each. Silverbars, on the other hand, are made much larger, often weighing 1,000 or 1,200 ozs.

Goldflotation. Flotationprocessis widely used for lodegold processing. In most cases, the flotation method has a good effect in sulfide-containinggoldore with high floatability. In addition, the flotationprocessis also used for polymetallicgold-bearing ores such asgold-copper,gold-lead,gold…

The Millerprocessuses gaseous chlorine to extract impurities whengoldis at melting point; impurities separate into a layer on the surface of the molten purifiedgold. The Millerprocessis rapid and simple, but it producesgoldof only about 99.5 percent purity. The Wohlwillprocessincreases purity to about 99.99 percent by electrolysis.

Goldrefining is aprocessthat involves recoveringgoldmetal fromgoldore and converting it to puregold, free from impurities. There are severalrefining systems used to make gold bars. Electrolyteprocess, chemical treatment, smelting and cupellation are some of the common refining methods used to makegold bars.
