separate concentrat Examples would include a lead-zinc ore, in which the lead and zinc minerals are recovered sequentially into separate concentrat Another example would be a copper-molybdenum ore in which the copper and molybdenum minerals are first recovered into a bulk copper-molybdenum concentrate, which is subsequently conditioned with
The association of gold and copper mineralization in commercially viable ore is a common occurrence At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value
The actual dressing recovery rate (%) = gold concentrate gold ore gold content (g) / (g) * 100% For a magnetic separation of iron ore beneficiation process factory, the known ore grade α =35 86%Fe, the concentrate grade β=60-89% Fe, tailings grade V =8 76% Fe, the yield of iron concentrate γk:
The ore then collapses – or “caves” – gradually under its own weight The resulting rubble funnels through a series of vertical ore passes at various levels in the mine A chute system is located at the bottom of each ore pass “The chute is a device that allows ore to be transferred safely to the haulage vehicles,” Meloche explained

The concentration of gold in the Earth's crust and mantle is extremely low and highly variable, resulting in ore variability in many gold and copper–gold deposits More importantly, gold in an ore may occur in two or three forms (ie, microscopic gold, submicroscopic gold, and surface gold), making gold ore processing extremely challenging
The differences in the form and solubility of the transporting gold and copper complexes, combined with their differing responses to variations in physicochemical conditions, meant that copper and gold in the ore-forming fluids precipitated differently, resulting in the temporal and spatial separation of copper and gold mineralization
