Applications

An 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 ore, and then collect the leaching solution to remove impurities, precipitation, pressing, burning, rare earth raw ore, about 5 tons of ammonium sulfate for each ton of rare earth raw ore mined and produced.

There are also many biological uses, mostly used in protein purification process, because ammonium sulfate is an inert substance, not easy to react with other bioactive substances, in the purification process can maximize the protection of protein activity, in addition, ammonium sulfate is extremely soluble, can form a high salt environment, for protein precipitation and subsequent high salt purification preparation. There is a big difference between the solubility of ammonium sulfate at zero and 25 degrees at room temperature. The following is the molar concentration of ammonium sulfate at different saturation at two temperatures.
