ammonium sulfate production from gold mineral processing

The invention particularly relates to a production process for ammonium sulfate granules, which solves the problems that production cost is high and a crystallization granulating process is narrow in applicability and has limitation due to the fact that phosphate is utilized as additives for granulating during existing extruding granulation of ammonium sulfate.

Dec 12, 2017 Ammonia and Ammonium sulfate were used as lixiviants. The pH of the solution was adjusted by changing the ratio of ammonium ions (NH4+) to free ammonia (NH3). The pH of the solution was measured at room temperature and unless otherwise mentioned, this value was kept constant at 10.2. Sodium sulfate was used as the supporting electrolyte.

When the manganese ore is leached to a concentration in solution of 100 g Mn per liter, the equivalent ammonium sulphate formed is 24.7 lb per 100 lb of water. This is neglecting the ammonium sulphate formed from the precipitation of the impurities of iron, alumina, and silica.
