Character of Gold Ore Bodies A very common occurrence of gold ore is in true fissure veins even and perhaps more abundant in seams or layers in close proximity to the hanging wall occasionally migrating across the fissure vein and then in close proximity to the footwall Fissure veins often fluctuate greatly in value so that the ore

Operations Goldex Agnico Eagle Mines Limited

Ore is treated using a two stage crushing process followed by a two stage grinding circuit that consists of a semi autogenous grinding mill and a ball mill Most of the ground ore is fed to a gravity circuit that recovers about two thirds of the gold which is then smelted on site to form doré bars Flotation recovers the rest of the gold producing a gold bearing pyrite concentrate

Establishing thE ProcEss MinEralogy of gold orEs

Some metallurgical implications to these gold ore types are summarised below Placers quartz vein gold ores and oxidized ores Generally placers quartz vein gold ores and oxidized ores are free milling and gold can be recovered by gravity and/or direct cyanide leaching Some epithermal deposits may be free milling such as the oxidized portion but more commonly contain significant amounts

Grinding Mineral Processing

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine Ball mills produce fine particles with a uniform size for flotation its grinding medias commonly are steel ball The ball mill rolls grinding media together with the ore as the ore grinds these balls initially 5 10 cm in diameter but gradually wear out


• Integrate with visual or other rock classification systems POWER OPTIMISATION For the most productive milling operation it is often best to operate close to the maximum mill power draw The power load relationship is highly non linear and shifts around as the ore and steel load/liner changes Traditional control and modeling techniques can therefore not be used Mintek has developed a Po

Goldroad and the Oatman Mining District

The Gold Ore Mine approximately half a mile north of the Gold Road Mine started using the Gold Road mill to process its ore near the end of 1913 The Gold Ore Mine produced ore that was valued at $ per ton which equated to approximately $ per ton of pure profit Stein 1993 By 1916 the mill was processing around 1 000 tons of ore from the Gold Ore Mine and the Gold Road Mine
