Nickel Smelting and Refining. 351. should be recycled. To the extent possible, all process effluents should be returned to the process. Treatment Technologies. The discharge of particulate matter emitted during drying, screening, roasting, smelting, and converting is controlled by using cyclones followed by wet scrubbers, ESPs, or bag ...
Oct 01, 2017· The experiments of agitation leaching were carried out in aqueous ammonia/ammonium carbonate solution, to recover copper from the flotation tailings of waste copper oxide residue. The main copper minerals contained in the flotation tailings are chrysocolla, malachite, and cuprite, with the copper grade of %.
Patent US Ammonia leaching Google Patents An improved process for obtaining copper from a copper sulfide in which the copper sulfide is treated with oxygen and an aqueous leaching solution of ammonium carbonate to form a leach liquor which contains ammonia complexes of copper sulfate and copper carbonate the leach,...
The leaching kinetics of zinc silicate in ammonium chloride solution was investigated. The effects of stirring speed (150–400 r/min), leaching temperature (95–108 °C), particle size of zinc silicate (61–150 μm) and the concentration of ammonium chloride (– mol/L) on leaching rate of zinc were studied.
Leaching of copper from tailings using ammonia/ammonium, The leaching of copper from the tailings of Baifang Copper Mine in Hunan province in China by aqueous ammonia/ammonium chloride solutions has been studied The tailings belong to a lowgrade and highalkaline copper ore The effect of.
Iron present in the residue in the reduced state, is readily recycled to the EAF unit. The Bureau of Mines treated copper converter flue dust (Palumbo et al., 1985) with hot solution of ammonium chloride and ammonium hydroxide to dissolve zinc oxide leaving tin, copper, lead and zinc in the residue.
Caustic soda lye is sodium hydroxide in solution. The solution can be diluted to 50% or 32% depending on intended application. Some gold miners in trying to bypass the challenge of having to open bags of caustic soda, are opting to install tankers onsite for storage of caustic lye, the introduction of which is controlled by a series of valves.

Of lowgrade oxide ore leaching with sulfuric acid from the solution using ion exchange process or the extraction of pure molybdenum trioxide. In addition, molybdenum concentrate smelting method, as well as lime roasting method, nitrate leaching, sodium hypochlorite leaching and electrooxidation leaching.
Response surface methodology is used to optimize the leaching process for refractory flotation copper tailings. The proportion of the refractory combination oxide copper (chrysocolla) is %. At present, few studies have examined the leaching of chrysocolla. In this study, we examine the effects of several variables, including the amount of concentrated sulfuric acid, leaching temperature ...
