1. Ammonium sulfate is an excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters, can be used as base fertilizer, topdressing and seed fertilizer.
2. It can be combined with salt to produce ammonium chloride, and aluminum sulfate to produce ammonium alum, with boric acid and other refractory materials.
3. Adding ammonium sulfate to the plating solution can increase electrical conductivity.
4. It is also the catalyst of food sauce color, the nitrogen source of yeast culture in the production of fresh yeast, acid dye dyeing aid, leather deashing agent.
5. In addition, it is also used for beer brewing, chemical reagents and battery production.
6. One of its important role is the mining of rare earth, the mining of ammonium sulfate as raw materials, the use of ion exchange form to exchange the rare earth elements in the mineral soil, and then collect the leaching solution to remove impurities, precipitation, pressing, burning after the rare earth raw ore, about 5 tons of ammonium sulfate per mining production of 1 ton of rare earth raw ore.
