摘要:Abstract(#br)In the traditional alkali smelting process of tungsten ore,a small amount of the associated phosphorus will enter the sodium tungstate solution. In order to produce a qualified tungsten product, phosphorus must be removed in depth. Conventional methods for remov...

摘要:Abstract(#br)Activated carbon has been found to significantly enhance the dissolution of gold in a thiosulfate‑oxygen‑copper system. Leaching tests using gold powder showed that the gold dissolution in a thiosulfate‑oxygen‑copper system in the absence of activated carbo...

摘要:Abstract(#br)In gold (Au) hydrometallurgy, ammonium thiosulfate is the most attractive and promising alternative to conventional lixiviants like cyanide or the halides because it is non-toxic, less corrosive and has high selectivity for Au. However, its industrial-scale appl...

摘要:Abstract(#br)The redox potential dependence of chalcopyrite leaching was investigated in acidic ferric chloride solutions using a specially designed batch leaching experimental setup that accurately determined and monitored the redox potential changes with time. The concentr...

摘要:Abstract(#br)Heap chloride leaching of low-grade copper sulfides with the use of seawater has been proposed as a feasible alternative to address challenges associated with water scarcity and depletion of oxides. Our previous study of leaching kinetics showed that the leachin...
