The second gave a concentrate containing $20.20 gold, 7.8% copper, and 27% insoluble, with an extraction of 64.5% of gold and 91.8% copper. The gold left in the tailing was probably in the gangue, as the extraction was poorer than usual. As a rule, the longer agitation and separation are continued, the more silicious the concentrate is.

Copper–gold ore processing (higher copper values than gold values) generally involves flotation and smelting. In the latter case, gold credits are obtained from the smelting of the copper concentrate, and if gold reports to the flotation tailings, they may also require cyanidation. A notable and relevant exception to this generalization is ...

Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods for the …

As expected, the copper in the circuit reduced to a low level, but when sulfide copper–gold ore processing resumed, the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined. The copper recovery plant was operated intermittently for a few months and was eventually shut down.
