Theflotationprocess in general doesnotfloat freegoldparticles but is particularly effective whengoldis associated with sulfidemineralssuch as pyrites. In a typical pyryticgold ore, thegoldis encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally donotrespond well toflotation.

For more than a century now,flotationhas been at the heart of themineralprocessing industry. In this month’s SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players inmineral flotation, a technique that is so important to the global industry.
Theflotationreagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of theflotationreagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the frothcelltailings.Expensivenuclear-based sensors have been tried with limited success.

The most prominent is nativegold- most of the nativegoldcontains a small amount of silver, copper, platinum, etc. Telluridemineralsare the most commonmineralswhich contain significantgoldin their make up. They include: Petzite (Ag,Au) 2,Te, with agoldcontent of about 25 per cent.
Preciousmineralsmake the modern world go 'round—they're used in everything from circuit boards to tableware. They're also some of the most toxic materials known to science, and excavating them has proved so dangerous over the years, some have been phased out of industrial production altogether. Listed below are the 10 most deadlymineralson earth.

After calaverite, sylvanite is probably the next most important tellurideore mineral. It can assay as high as 30%gold. It is found with other telluridemineralsin some precious metaloredeposits. Petzite: Agoldand silver telluride that is mostly silver. Silver content is usually three times that ofgold.
