How to Separate Gold from Pyrite. Previous Next 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 physical state and the causes of its

Effect of microwave heating on magnetic separation of pyrite

The effect of microwave heating on magnetic processing of pyrite was investigated. Different size fractions of pyrite were treated (heated) in a microwave oven at 2.45 GHz frequency and different power levels. The microwave treated pyrite samples of −420 μm fraction were subjected to magnetic separation at magnetic field intensities of 0.1, 0.3 and 0.5 T. It was found that pyrite was

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

Pyrite Wikipedia

Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scaly-foot gastropods. Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold.
