Some Uses Of Ammonium Sulfate

An excellent nitrogen fertilizer (commonly known as fertilizer field powder), suitable for general soils and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, and enhance crop resistance to disasters. It can be used as base fertilizer, top dressing and seed fertilizer. It can be meta-decomposed with salt to produce ammonium chloride, which reacts with aluminum sulfate to form ammonium alum, and together with boric acid, etc., to produce refractory materials. Adding to the plating solution increases conductivity. It is also a catalyst for food coloring, a nitrogen source for cultivating yeast in the production of fresh yeast, an acid dyeing dyeing aid, and a leather deashing agent. In addition, it is also used in beer brewing, chemical reagents and battery production. Another important function is to mine rare earth, extract ammonium sulfate as raw material, exchange rare earth elements in the ore by ion exchange, and collect the leaching solution to remove impurities, precipitate, press and burn, then form rare earth ore. About 1 ton of ammonium sulfate is required for 1 ton of rare earth ore.
