Ukusetshenziswa kwe-lead-zinc ore kumele kuhlomule ngaphambi kokuthi kusetshenziswe kangcono. Indlela esetshenziswayo esetshenziswa kakhulu yi-flotation. Njengoba kungukugcwala, amakhemikhali we-flotation ngokwemvelo ahlukaniseki. Okulandelayo ukwethulwa kwe-reagents ye-flotation esetshenziswe ku-lead-zinc ores:
1. Ukuhola kanye nama-Zinc Flotation Alawuli: Abalawuli bangahlukaniswa ngama-inhibitors, ama-activators, abalawuli be-medium PH, abahlubuki be-slime, ama-coabulents kanye nama-couagulants abo ngokwezifiso zabo. Abalawuli bafaka amakhompiyutha ahlukahlukene e-Inorganic (afana nosawoti, izisekelo kanye nama-acid) nezinto eziphilayo. Umenzeli ofanayo uvame ukudlala izindima ezahlukahlukene ngaphansi kwezimo ezahlukahlukene ze-flotation.
2. Ukuhola kanye nabaqoqi be-zinc flotation. Abaqoqi abasetshenziswa kaningi bafaka: XANTHATE kanye nomuthi omnyama. Isigaba se-Xanthate sifaka i-Xanthate, i-Xanthate Esters, njll. Isigaba se-Sulfur Nitrogen, njenge-Ethyl Sulfide, inamandla okuqoqwa okunamandla kune-Xanthate. Inamandla okuqoqa okuqinile kwe-Galena ne-Chalcopyrite, futhi namandla ayo weqoqo le-pyrite ayalinganiswa. Okubuthakathaka, ukukhethwa okuhle, isivinini esisheshayo se-flotation, ewusizo kancane kune-xanthate, futhi inesilinganiso esinamandla sokuthwebula sezinhlayiya ezihlanganayo zama-sulfide ores ashes. Lapho isetshenziswa ekuhlukanisweni kwe-Copper-Lead-Sulfur Ratio Ores, ingathola okungcono kune-Xanthate. Umphumela wokuhlunga okungcono. I-Black Medicine Emnyama Medicine ngumqoqi ophumelelayo we-sulfide ores. Ikhono layo eliqoqiwe libuthakathaka kunale leXanthate. Umkhiqizo we-solubity we-dihydrocarbyl dithiophosphate we-ion efanayo yensimbi mkhulu kunalokho kwe-xanthate ye-ion ehambisanayo. Umuthi omnyama unezinto ezigwebu. Ama-powders ajwayelekile asetshenziswa embonini afaka: Cha. 25 Black powder, i-Butylammonium Black Powder, Amine Powder Powder, kanye ne-Naphthenic Black Powder. Phakathi kwazo, i-bubylammonium black powder (i-dibutyl ammonium dithiophosphate) iyimpuphu emhlophe elula kakhulu ingena kalula emanzini, iphenduka ibe mnyama ngemuva kwe-deloscence, futhi inezakhiwo ezithile ze-fooming. Ilungele ukugcwaliswa kwe-arfide ores enjengethusi, ukuhola, i-zinc, kanye ne-nickel.
Ngaphezu kwalokho, i-Cyanide ingavimbela kakhulu i-sphalerite, ne-zinc sulfate, i-thiosulfate, njll. Ingavimba ukugcwaliswa kwe-sphalerite.
