Gold extraction
Gold occurs principally as a native metal, ie, gold itself Sometimes it is alloyed to a greater or lesser extent with silver, which is called electrum Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as colour) embedded in rock minerals Other forms of gold are the minerals calaverite (AuTe), aurostibnite (AuSb2), aTypically, gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores, even Recovery of gold from sulfide refractory gold ore:

Auric Mining signs deal to become next WA gold producer
22 Auric Mining is set to become WA’s next gold producer after executing a 150,000 tonne gold ore toll milling agreement with the Greenfields Mill at Coolgardie for its Jeffreys Find gold deposit near Norseman In a major milestone for the company mining will commence in early April with the 150,000 tonnes of ore to be delivered to the mill The gold ore produced is refined at Sumitomo Metal Mining’s Toyo Smelter & Refinery in Ehime Prefecture, and there it becomes pure gold with a purity of 9999% The average production of around six tons per year is an enormous amount compared to gold mines of the past in JapanA Worldleading Gold Mine in Modern Japan March 2023
