Gold Ore Sorting : TOMRA
Gold ores are typically amenable to sensor-based ore sorting to some degree, and this is usually accomplished with XRT or laser sensors, or a combination of both. A two-step sorting flow-sheet consisting of an XRT rougher plus a laser scavenger (or alternatively, a laser rougher and an XRT scavenger) has already proved an optimal recovery

Gold parting Wikipedia
Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to

Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent.
