Cyanide (nacn, Kcn)
Cyanide bụ ihe dị irè na-arụ ọrụ n'oge ndu na ịhazi. A na-ejikwa cyanide bụ sodium carium na potassium cyanide, ejikwa cyanide. Nnu na-eme nnu site na ala siri ike na acid na-esighi ike. Ọ hydrolyzes na slurry iji mepụta Hcn na CNˉ
Kcn = K⁺ CNˉ CN + H₂O = HcN⁺ + Ohˉ
Site na nha anya dị elu, enwere ike ịhụ ya na alkaline pulp, ịta CNˉ na-abawanye, nke bara uru na nsogbu.

Zinc sulfate
Ngwaahịa dị ọcha nke zinc sulfate dị ọcha kristal, ọ na-agbanye ya na mmiri, ma na-egbochi sphalerite. Ọ na - enwekarị inhibitory mmetụta naanị na alkaline slurry. Nke dị elu ph nke slurry, mmetụta ya pụtara ìhè karị. Zinc sulfate na-emepụta mmeghachi omume ndị a na mmiri:
ZNSO₄ = ZN²⁺ + so
ZN1 + 2HO = ZN (Oh) ₂ + 2h⁺zn (oh) ₂ bụ usoro amphotoric nke na-agbanye nnu
