Chlorination leaching is used in PGM refineries around the world. Table summarizes the feed materials, chlorination conditions, and gold recovery methods and efficiencies within the refinery processes (adapted from information provided in Crundwell et al., 2011).The feedstocks are highvalue, lowvolume materials often derived from base metal refineries, typically containing ∼25% Pt ...

 · Those skilled in the art will recognize that at very high levels of carbonaceous and/or sulfidic matter the costs of pressure chlorination may become excessive, depending on the gold content of the ore, the market value of the recovered gold, and other factors. Thus, other processes may be preferred for gold ores containing excessive levels of carbonaceous and/or sulfidic material.

If you're processing a high sulphide content gold ore this will not work. With high sulphide gold ore break it down and separate it till all you see is the yellow shiny stuff then take that and put it into a hydrochloric acid solution and let it sit for a week or so swirling it in bottom of container occasionally. Pour off your acid and save in another container so you can use it later just ...

The chlorination process, which is obsolete by now, used chlorine gas that was conducted through wet, precrushed gold ore forming soluble gold chloride that could be washed out with water. The dissolved gold was eventually precipitated from the aqueous solution by ferrous sulphate. The rather common cyanide leach process is based on the selective solubility of gold in a weak cyanide solution ...

The Newbery–Vautin chlorination process is a process to extract gold from its ore using chlorination developed by James Cosmo Newbery and Claude Vautin.. Background. The process of gold extraction from ores via its absorption in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery.
