The application of ammonium thiosulfate for the treatment of copper-gold ores has been investigated. Leaching studies were conducted with copper minerals, copper minerals with gold addition to solution and copper-gold samples of different copper and gold grades. The behaviour of thiosulfate, tetrathionate and sulfate in solution was studied using ion chromatography. The copper sulfide minerals ...

Jan 02, 2012018332A leaching of 56.7 gold was obtained under the optimum condition of 0.1M ammonium thiosulfate, 40 mM copper sulfate, pH 10-10.5, pulp density 10 gL at room temperature and stirring speed of 250 rpm in 8h duration. The maximum leaching of gold in the pH range 10-10.5 may be attributed to the higher stability of the ammonium thiosulfate.
Apr 07, 2013018332Sodium Thiosulfate will leach all of the salts of silver and gold and leave a colorless solution. Pgm salts will leave an orange to red solution. Ammonium Thiosulfate is an alternative to cyanide leaching. It will leach gold, generally at a higher redox rate than cyanide, but does not recover well on charcol. Most such systems use resin recovery.
ATS Ammonium Thiosulfate. Ammonium Thiosulfate ATS 12-0-0-26S ATS is a standard product of the U.S. fluid fertilizer industry. Adding Ammonium Thiosulfate ATS 12-0-0-26S to UAN solutions is the economical, effective and convenient way to stabilize and
Copper is oxidatively leached from a copper bearing ore in the presence of a catalytic amount of silver ions to decrease leaching times. The oxidative agent may be ferric sulfate, dilute sulfuric acid in the presence of added oxygen, or concentrated sulfuric acid.
ammonium sulfate production from gold mining. ammonium sulfate production from gold mining qlife.be. Ammonium Sulfate Suppliers and An important role is also rare earth mining, mining ammonium sulfate as raw materials, the use of ion exchange in the form of the mineral soil in the rare earth exchanged out, and then collect leachate impurity removal, sedimentation, pressing, after
performed by using this ore. In this work, the leaching kinetics of malachite in ammonium sulfate solutions was investigated, and metallic copper was recovered by a cementation method from the resulting actual leach solution. Copper II oxide was prepared by an isothermal oxidation method from the cement copper. In the
Jan 11, 2012018332When we mix the sodium thiosulfate with the ammonium sulfate, we were told to use a very small amt of copper sulfate, as well. Those three put the ph at about 7.5 after we add the ore. Some people on this forum have said the ph needs to be between 9 and 9.2, others have said no more than 8.
Abstract. Metal leaching from a low-grade nickel ore was investigated using an ammonium sulfate roasting-water leaching process. The nickel ore was mixed with ammonium sulfate, followed by roasting and finally leaching with water.
Gold and silver recoveries from PCBs waste were tested through the medium of ammonium thiosulphate in the presence of cupric sulphate and ammonia. Lead and tin recoveries were tested through leaching by sodium chloride. For palladium leaching aqua regia was used. The leaching was investigated under conditions given in Tab. 2.
May 22, 20100183322006. Q. Precipitate gold from aqua regia. Im investing about gold precipitating from aqua regia. I know sodium metabisulfite, ferrous sulfate. But I want to learn more about hydrazine hydrate, SO2, formaldehyde, hydroquinone and Oxalic Acid. affil. link to product info at Rockler.My company will begin to use aqua regia process for refining gold can you give me an answer about
Metal leaching from a low-grade nickel ore was investigated using an ammonium sulfate roasting-water leaching process. The nickel ore was mixed with ammonium sulfate, followed by roasting and finally leaching with water. During the process the effects of the amount of ammonium sulfate, roasting temperature, and roasting time on the leaching recovery of metal elements were analyzed.
Aqueous feed solutions used in solvent extraction SX studies were pregnant leach solutions PLS generated in pressure ammonia leaching of commercial flotation concentrate. Leaching with ammoniaammonium sulfate solution resulted in leach liquors PLS containing 8 gdm3 CuII, 0.58 gdm3 ZnII, 15 mgdm3 NiII and 45 mgdm3 CoII. The ...
The residue from desulfurization and denitrification of exhaust gas treatment process with pyrolusite ore as absorbent is regarded as a potential source of iron and manganese. In this study, an extraction process is proposed for recovery of iron and manganese with ammonium sulphate roasting followed by sulphuric acid leaching. Firstly, the conversion mechanism was analyzed through mineral ...
An ammonium sulfate-based AMS liquid adjuvant plus deposition aid designed to maximize the performance of glyphosate, glufosinate, and other non-selective herbicides that are adversely affected by hard water calcium cations. AMAZE GOLD is currently not registered for sale or use in California.
