How To Use Ammonium Sulfate For Gold Leaching

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 ...

Leaching Of Gold From The Waste Mobile Phone Printed

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.

Thiosulphate Droppedtesting For Pm Page 2 Gold

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.

Recovery Of Valuable Metals From A Lowgrade Nickel Ore

Recovery Of Valuable Metals From A Lowgrade Nickel Ore

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.

Leaching Of Gold Silver And Accompanying Metals From

Leaching Of Gold Silver And Accompanying Metals From

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.

Recovery Of Valuable Metals From A Lowgrade Nickel Ore

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.
