3) Metathesis reaction: Dissolve the sulfide in distilled water to obtain a clear decomposition liquid, and add nonionic surfactant to stir evenly, then slowly add it to the zinc sulfate ammonia complex solution to form a metathesis reaction, and obtain Lide powder opacity. The liquid is separated by filtration, and the separated ammonia liquid is returned to the leaching after ammonia adjustment, and the separated nZnS-BaS0 4 crystal filter cake is put into the next step;
