A review of the flotation of native gold and electrum

Native gold and electrum are naturallyoccurring alloys containing gold and silver and a little copper. They are the most common and important forms of gold in ores. Their recovery by gravity concentration, cyanidation, or flotation from ores, typically containing 0.120 g/t Au is of great commercial importance.

Electrum, pyrargyrite, acanthite, and tetrahedrite were identified to be the most important silverbearing phases in the ore. A flotation concentrate with a high silver grade 0.6 Ag at 94.8 silver recovery, as well as high recoveries of antimony 86.8 , zinc 98.6 , and lead 84.7 , was produced in flotation tests.
