1. Ammonium sulfate is an excellent nitrogen fertilizer, which is suitable for soil and crops. It can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance the resistance of crops to disasters. It can be used as base fertilizer, top dressing and seed fertilizer.
2. Ammonium sulfate is used to mine rare earths. Ammonium sulfate is used as raw material for mining, and the rare earth elements in the ore are exchanged in the form of ion exchange.
3. Ammonium sulfate is used in protein purification process.
