Copper–gold ore processing with ion exchange and SART
The successful operation of Anglo Asian Mining’s Gedabek process plant, which uses a unique combination of ion exchange for gold extraction and SART technology for copper control, has demonstrated a new route for the treatment of copper–gold ores, which in the past have proved difficult to handle with conventional gold processing Nigeria gold processing plant processed the mud-containing alluvial gold and placer gold ore, mostly in the form of particles. Its production capacity is 80 t/h. The feed size is 0-200 mm, and the placer gold size is 0-3 mm. The gold processing plant uses the gravity separation method, and the equipment is configured as a trommel screenGold Processing Plants in Nigeria, South Africa and Tanzania

Copper–gold ore processing with ion exchange and SART technology
The Gedabek mine is a conventional open pit, truck and shovel operation, with a current mining rate of about one million tons of ore per year, resulting in an annual gold production of approximately 50,000 oz. Rock breakage is accomplished by blasting, which is carried out once per day.Blast holes are drilled on a 2.5 m × 2.5 m pattern in ore Shaking table, also called gold recovery table or gold separation table, is the best fine gold recovery equipment. It can process both gold ore in quartz rock, gold stones, and placer gold. The feeding particle size range of the shaking table is generally between 3mm-0.019mm.

Flotation of Gold and Gold-Bearing Ores ScienceDirect
Application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals, followed by the installation of pyrite flotation plants on numerous gold Mining is one of the oldest economic activities of mankind. Within this activity, artisanal and small-scale gold mining (ASGM) is one of the most studied sectors due to its high level of environmental contamination and the social problems it causes. In recent years, ASGM in the northern Amazon of Ecuador has increased significantly, and studies Artisanal and Small-Scale Gold Mining (ASGM): Management

Selective attachment processes in ancient gold ore
Various properties of gold can be utilized for beneficiation depending on the particle size. At particle sizes below 100 μm, the mass forces utilized in the gravity-hydraulic processes weaken, and surface forces become increasingly important (Allan and Woodcock, 2001).These surface forces cause selective attachment through electrostatic, After solid–liquid separation and iron precipitation, gold and silver can be cemented using Zn powder; the zinc chloride solution is then processed to metal using the TR electrowinning cell (Frías et al., 2000, Frías et al., 2002).

Analysis of the gold recovery profile through a cyanidation plant
Leaching in the grinding circuit is currently practiced in plants that process gold ores with low content of cyanide consuming minerals. The high gold recovery observed in the grinding–classification section of the plant is commonly explained by the inherent high initial dissolution rate of gold observed in gold ore cyanidation, or by the intense agitation 01 Step #1: Crushing and Screening. The gold ore crushing process often uses jaw crusher for coarse crushing, standard cone crusher for medium crushing, and short head cone crusher and roll crusher for fine crushing.
