How to Separate Gold from Pyrite View Larger Image So far no account has been taken of the loss of gold which is contained in pyrites, as it has been assumed that these are saved by concentration if they are valuable, and this subject is dealt with in earlier Nevertheless, as this gold comes under the head of non amalgamable gold, its

A gold containing chalcopyrite concentrate has been treated with thiourea using H 2 SO 4 The effects of some leach parameters such as thiourea concentration, oxidizing agents, redox potential, pH, temperature, pulp density, acid pretreatment and SO 2 addition have been investigated Maximum gold and silver extractions are respectively 95 5 and 85 4

Chalcopyrite is the most important and major source of copper metal It is widely spread copperiron sulfide mineral with chemical formula CuFeS 2 The color is typically brass to golden yellow Fig 1 15, often tarnished, with greenish black streak and submetallic luster The hardness varies between 3 5 and 4 0 on the Mohs scale

Pyrite also known as fool's gold is a mineral that has both a different chemical, morphological and physical characteristics than gold Gold is denser i e the same size of gold is much heavier

Pyrite is harder, heavier, and exhibits a conchoidal fracture as opposed to chalcopyrite's brittle fracture Chalcopyrite also contains copper whereas pyrite does not How do you separate gold

GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S JONES and MICHAEL FLEISCHER ABSTRACT Gold occurs in nature mainly as the metal and as various alloys It forms complete series of solid solu­ tions with silver, copper, nickel, palladium, and

The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores Getting copper from chalcopyrite, CuFeS 2 Chalcopyrite also known as copper pyrites and similar sulphide ores are the commonest ores of

As well, if struck with a steel hammer gold will flatten or change shape without breaking but pyrite will give off sparks Chalcopyrite vs Pyrite Chalcopyrite looks similar to pyrite but it is softer and can be scratched with a knife It is a very brassy yellow, often with a bronze or iridescent tarnish whereas pyrite is simply a brassy yellow

Feb 03, 2016 The material should be crushed and the gold looking mineral concentrated by panning or some other method Then the concentrate should be smelted This will minimize any loss of gold Smelting uncrushed rock chunks like these will result in a large loss of gold in the slag as the gold will not separate cleanly from the rock

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

Fool's Gold can be one of three minerals The most common mineral mistaken for gold is pyrite Chalcopyrite may also appear gold like, and weathered mica can mimic gold as well Compared to actual gold, these minerals will flake, powder or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead In addition, actual gold will leave a golden

Chalcopyrite a copper iron sulfide has very similar properties to pyrite It has a lower hardness than pyrite 3 5 to 4 and a lower specific gravity than pyrite 4 1 to 4 3, but the same tests can separate chalcopyrite from gold Chalcopyrite also has a greenish black streak

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99 99 pure copper called cathodes, which will ultimately be made into products for everyday use The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different

Chalcopyrite has a golden yellow color, which often resembles Gold However, its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it Chalcopyrite is a beautiful mineral, with good crystals being fairly common

Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy

Recovering gold from copper concentrate via the HydroCopper process Over 85 of copper in chalcopyrite could be leached when present with other secondary copper sulfides When copper was

how to extract gold from chalcopyrite ore k consulting co za Gold extraction refers to the processes required to extract gold from its ores This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore

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 the existence of gold possessing a weak susceptibility to magnetism due to a fine coating of a iron compound

Gold is a highly valued mineral that may initially be confused with massive chalcopyrite Indeed, chalcopyrite is often referred to as Fools Gold The two may be distinguished by chalcopyrites color and brittle nature Chalcopyrite has a brassy yellow color that is distinct from golds more buttery yellow

The most obvious physical properties of chalcopyrite are its brassy yellow color, metallic luster, and high specific gravity These give it a similar appearance to pyrite and gold Distinguishing these minerals is easy Gold is soft, has a yellow streak and has a much higher specific gravity Chalcopyrite is brittle and has a greenish gray streak
