The Arequipa region has the third largest mining industry in Peru, producing 19.5 % of the country's annual gold in 2022 (Vera Gargurevich et al., 2023).Small-scale gold processing facilities (ore capacities up to 350 metric tons per day) play a large role in the industry, accounting for 40 % of the Arequipa region's gold production, with medium- (ore capacities of 350–5000 …
Our Recommendations on Tailings Management Gold production produces a lot of tailings, so there are a few things to keep in mind. First, the site selection of tailings ponds must be reasonable, which is the basis for the management and utilization of tailings ponds. Second, the exhausted tailings pond will be immediately overturned and reclaimed.

Therefore, the shale covering the yellow dump might be small amount of gold ore, but the yellow dumps are certainly not. In the Breck district, the ore bodies outcropped atop the hills (Eg. Gossans), but most of the gold rich oxidized material was sheared off and/or covered by glaciers or glacial melt down into the gulches.

Peko Magnetite, Gold & Polymetallic Peko Iron Ore and Gold Project is located in the Tennant Creek region in the Northern Territory. Peko consists of 3.75 million tonnes of tailings containing magnetite, gold, copper and cobalt, plus in-ground and stockpiled gold-bearing ore resources. Peko's operations are located 12km from the Adelaide-Darwin railway and 10km from…
The conversion of gold ore tailings into value-added products is an urgent problem that requires a solution. In this study, two different type of mixtures (with minor addition of activator to excite the activity of mechanically activated tailings, and a mixture of cement and tailings to determine activity index of tailings) were prepared to investigated the effect of …
