At the same time, Fe, Ca, Al, Mg plasma in coal gangue and improver can also form salt precipitation with SO42-, reducing the content of SO42- in the leaching solution
At the same time, Fe, Ca, Al and Mg plasmas in coltan and improvers can also be precipitated with SO42-generated salts to reduce the so42-content in the resulting fluid.
At the same time, Fe, CA, Al and Mg plasma in gangue and modifier can precipitate with so42- to form salt, and reduce the content of SO42 in the leaching liquid<br>
