Gravity separation is used in gold processing to recover the coarser particles, the finer being recovered by leaching (EC 2004). Refractory ores are commonly processed using pressure oxidation, bioleaching and roasting prior to leaching techniques. These types of pre-processing are often associated with ultra fine grinding that generates ...

Historic Gold Mine Tailings FAQ What are gold mine tailings? Tailings are a by-product of a gold mining process that was common in the late 1800s and early 1900s. Gold-bearing rocks that also contain arsenic were crushed and spread over liquid mercury to remove the gold. The mercury was then evaporated, leaving the gold. The remaining sand-like ...
