The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth's surface) and endogenetic (formed within the Earth). The best-known of the exogenetic ores is alluvial gold.

 — Wet Pan Mill Yes, I am interested!. Wet pan mill, also called gold grinder mill, is a versatile ore grinding pan mill for processing gold, silver, copper, etc. As an affordable alternative to ball mills, wet pan mills are ideal and efficient equipment for ore beneficiation in small and medium gold processing plants.

 — Lihir Gold Mine's ore processing capabilities. The mine was upgraded with the installation of one additional autoclave of twice the capacity of each of the three existing autoclaves, as well as additional crushing, grinding, thickening, oxygen, and leach plant facilities. The Lihir ore mill achieved a throughput capacity of 15Mtpa in 2019.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and …

 — The CIL process concentrates gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t on carbon. Although the earliest process was in South Africa in 1890, CIP/CIL was first introduced in gold processing in 1949 at San Andreas (Honduras) (Marsden and …
