    Home Home Albion Process

    Albion Process™ has real-world success in delivering consistently high recoveries up to 97% in refractory gold and over 99% in chalcopyrite copper concentrates. It has much lower capital cost than traditional leaching plants like pressure oxidation (POx) plants and because it operates at atmospheric pressure, it completely avoids the myriad of risks of POx plants.

    Process for treating refractory gold ores by roasting

    Microscopic gold inclusions in sulfide minerals cannot typically be extracted by conventional cyanidation. The gold ore must be pretreated to oxidize sulfide minerals associated with gold and to remove other minerals and chemical compounds that interfere in the cyanidation leaching process. The recovery of gold from refractory sulfidic-carbonaceous ores after roasting pretreatment was studied.

    Improved recovery of a low-grade refractory gold ore

    01/07/2014· In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.

    The mining history of the Sudbury area Earth Sciences

    Interestingly, though, the Vermillion Mine also contained a high-grade nickel-copper ore body, platinum, silver, tin and other minerals proving to be a forerunner of future Sudbury area mines. Iron has also been mined in Sudbury until recent times, and along with the already mentioned precious metal ores and others, has been a by-product of the nickel-copper mineral processing.

    Petropavlovsk says Pioneer refractory ore flotation plant

    Once operating at full capacity, the new flotation plant at Pioneer will double the group’s flotation capacity from 3.6 to 7.2 Mt/y. The crushing grinding lines are being gradually switched to the flotation circuit as ore transitions from non-refractory to refractory. Once operational, 3.6 Mt/y of milling capacity will be diverted away from the 6.7 Mt/y non refractory resin in pump (RIP) plant.
