Apr 24, 2017· Gold is an almost nonreactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
We want pure gold, but goldbearing rocks include lots of other materials such as quartz, calcite and the sulfides of other metals. We need to separate the gold from everything else in the rock so the rock needs to be treated in some way. In New Zealand we chiselled some rocks from an outcrop near a small creek.
Aug 05, 2018· One other distinct difference between pyrite and gold is the specific density difference. Gold is very heavy! Pyrite is not. The specific density of pyrite is 5 and the specific density of gold is over 19! That means that the same volume of gold weighs times that of pyrite. All methods of gold mining use this fact to separate gold from ...

Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of ...
To the untrained eye, pyrite looks quite similar to gold in the sense that it''s a similar yellowish color, but there are some notable differences between the two. Whether you''re a recreational of professional prospector, it''s important to know and understand the differences between pyrite and real gold.

Proper gold panning will easily separate the two, as the small specks of pyrite will wash out of the pan while the denser gold particles will be retained. The color is also a good indicator between the two. While gold obviously has a golden color, pyrite generally has a brassy and shiny coloration.
It has a lower hardness than pyrite ( to 4) and a lower specific gravity than pyrite ( to ), but the same tests can separate chalcopyrite from gold. Chalcopyrite also has a greenish black streak.
The gold occurs as tiny flakes on the crystallographic planes of the pyrite. The gold flakes are very small in size, 510 microns. The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and ...
How to Separate Gold from Pyrite Louis Janin, Jr, mentions another case in the ores of the Southern Cross Mine, Deer Lodge County, Montana, which consist of limonite derived from the alteration of pyrites In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton
