How to Separate Gold from Pyrite

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

Separating Flotation Gold From Pyrite

separating iron pyrite and gold found together in flakes. Pyrite was once used as a source of sulfur but is now only a minor ore for both sulfur and iron Pyrite from some localities is auriferous and therefore is used as an ore of gold in gold-bearing localities Pyrite was polished by the Native Americans in the early times and used as mirrors Today it is used as an ornamental stone as well as

Selective flotation of pyrite and gold tellurides

Mar 01, 1997· The separation of tellurides from pyrite can be carried out by selective flotation. The selection and dosage of collectors and pulp pH are very important to produce one concentrate containing tellurides and free gold, and a further concentrate containing pyrite.

US5171428A Flotation separation of arsenopyrite from

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings

How to Separate Specks of Fool's Gold From Specks of Real

Apr 12, 2017· Fool's gold, the mineral pyrite, has a metallic luster and gray or black streaks, and feels heavy for its size, although real gold is denser. Panning for gold and knowing how to separate it from fool's gold takes practice and an ability to work quickly with a prospector's pan.

Selective separation of chalcopyrite from pyrite with a

Sep 20, 2019· The single mineral flotation results showed that PGA depressed the flotation of pyrite more strongly than that of chalcopyrite in the wide pH range of 8–10. An improved selective separation between the two minerals in the presence of PGA was achieved at pH 9 in which the recovery of chalcopyrite was over 85% and that of pyrite was less than

Pyrite-gold recovery in copper rougher flotation tailings

The present study investigates the effect of regrinding and aeration on the separation of pyrite from gold in copper rougher flotation tailings (0.07% Cu, 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation.

A Brief Review of Auriferous Sulphide Flotation

flotation response. Separation of gold predominated arsenopyrite minerals from less economical pyrite phase maximises downstream unit feed and improves financial performance of the operation. This paper briefly reviews attempts made thus far in exploiting subtle differences between pyrite and arsenopyrite for separation.

Rcovery of gold in pyritic ores Mine Engineer.Com

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).
