Mined gold-bearing ore containing gold and silver is extracted and purified through a processing plant. In this gold recovery plant, the precious metals are extracted from the ore through a series of steps including: crushing and grinding; addition of process water (forming a slurry); cyanide leaching; floatation and vortex separation (cyclones).
The gold milling plant consists of a 3t/hr gold ore milling and recovery equipment plant, a gold room, an office block, a guard room, a 200KVA 11/0.4 Substation and a 11KVA powerline that links the centre to the national grid and two boreholes with one connected to a solar powered pumping system and 2 x 10,000l water storage tanks.

Gold Ore Roasting Plant. To achieve optimum gold recovery from the certain sulfide ore body, the ore must be finely ground to achieve proper oxidation and mineral separation. The ore is separated into stockpiles after it has been mined. These stockpiles are based on gold content, sulfide content, and carbonate content.
The mineralogy of gold ore deposits ranges from free-milling, metal oxide ores, to sulphides. The sulphide ores tend to be refractory to leaching when employing a normal cyanidation process. Recoveries of gold, when employing a normal cyanidation process in the treatment of sulphide ores, tend to be less than 80%.
Today, Outotec can offer processes and equipment that cover the full gold value stream from ore to dore.

Gold Ore Milling Process. Their method of mining was then, and is now, the following: A small water-furrow is first brought in at the highest possible level on a suitable hill-side, and the stream is turned down the hill. By means of a heavy long wooden crowbar, shod with a long strongly- made chisel-pointed iron socket, and with the help of ...
The feed to the plant during 2020 and 2021 was between 11.0 and 12.1g/t Au and 3.5 to 4.5% Sb. The gravity gold production varies but recoveries are typically around 40 to 50%.
