8.4.1 General1-2. Ammonium sulfate ([NH4]2SO4) is commonly used as a fertilizer. In 1991, U. S. facilities produced about 2.7 million megagrams (Mg) (3 million tons) of ammonium sulfate in about 35 plants. Production rates at these plants range from 1.8 to 360 Mg (2 to 400 tons) per year. 8.4.2 Process Description1.

The experiments were carried out at an optimum temperature of 400 °C and a concentrate to ammonium sulfate ratio of 1:7. Grinding the mixture to −50 μm recovered 87.1% nickel and 81.4% copper. Finer grinding made it possible to increase the recovery of non-ferrous metals. 95.3% of nickel and 92.1% of copper was recovered into the solution.

Ammonium Sulfate is an inorganic salt with (NH4)2SO4. Its IUPAC name is Ammonium tetraoxosulphate (VI). It is also known as DiAmmonium Sulfate, sulphuric acid, diAmmonium salt, mascagnite, and dopamine. It is a white odorless solid that sinks and dissolves in water. This salt is made by making ammonia react with sulphuric acid.
