Although some alternative reagents can give higher gold extractions with carbonaceous or refractory gold ores (Wan et al., 1995; Choi et al., 2013), cyanidation often achieves the highest overall gold recovery. For high-grade ores and concentrates, the economic benefit of increased gold recovery usually outweighs the reagent cost and …

Quartz is classically aligned with gold.The majority of hard rock deposits found appear to occur in quartz, and gold-in-quartz has even taken on a life of its own. The gold that appears in quartz is almost universally native, meaning that it's in a metallic form contained in the crystalline quartz. It's universally considered the richest of the gold …

As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores suitable for gold recovery strictly by this method.

of gold process operating costs. As an illustration, for a gold ore grading 2.3 g/t, a 1% increase in gold recovery generates incremental revenue of about $1/t-ore at a gold price of $1,300/ oz. For cyanide at a price of $3,600/t delivered to a remote mine site, it takes only 0.28 kg/t-ore consumption to equate to $1/t-ore, or 1% gold recovery.

Gold and silver can be recovered from their ores by a variety of methods, including gravity concentration, flotation, and agitated tank leaching. Methods similar to heap leaching can be employed: dump leaching and vat leaching (vat leaching is the treatment of sand or crushed ore in bedded vats with rapid solution percolation).

High-pressure oxidation comprises the oxidisation of sulphide/carbonaceous gold ore at high pressure and temperature. Temperatures exceeding 200 °C and oxygen pressures above 2200 kPa are used to attain complete oxidation of the gold-bearing ore. Reaction rates can be very fast, and the technology is widely-accepted.
