Har'a mefuta e mengata ea liminerale, li-lead-zinc ore ke ore eo ho leng thata ho e khetha.Ka kakaretso, li-lead-zinc ore li na le li-ore tse futsanehileng ho feta li-ore tse ruileng 'me likarolo tse amanang le tsona li rarahane haholo.Ka hona, mokhoa oa ho arola lead le zinki ka nepo le tsona ke taba ea bohlokoa indastering ea ho lokisa liminerale.Hona joale, liminerale tsa lead le zinki tse fumanehang bakeng sa tšebeliso ea indasteri ke haholo-holo galena le sphalerite, hape li kenyelletsa smithsonite, cerussite, joalo-joalo Ho ea ka tekanyo ea oxidation, liminerale tsa lead-zinc li ka aroloa ka lead-zinc sulfide ore, lead- zinc oxide ore, le ore e tsoakiloeng ea lead-zinc.Ka tlaase mona re tla hlahloba ka ho khetheha mokhoa oa ho arohana ha li-lead-zinc ore ho latela tekanyo ea oxidation ea li-lead-zinc ore.

Mokhoa oa ho arola ore ea lead-zinc sulfide
Har'a tšepe ea lead-zinc sulfide ore le lead-zinc oxide ore, ho bonolo ho hlophisa ore ea lead-zinc sulfide.Hangata ore ea lead-zinc sulfide e na le galena, sphalerite, pyrite, le chalcopyrite.Liminerale tse ka sehloohong tsa gangue li kenyelletsa calcite, quartz, dolomite, mica, chlorite, joalo-joalo Ka hona, ho ea ka kamano e kentsoeng ea liminerale tse molemo tse kang lead le zinki, sethala sa ho sila se ka khetha mokhoa o mong oa ho sila kapa mokhoa oa ho sila oa mekhahlelo e mengata. .

Mokhoa oa ho sila oa mohato o le mong hangata o sebelisoa ho sebetsana le li-lead-zinc sulfide ores ka boholo ba lijo-thollo tse mahoashe kapa likamano tse bonolo tsa symbiotic;

Ts'ebetso ea ho sila ka mekhahlelo e mengata e sebetsana le li-lead-zinc sulfide ores tse nang le likamano tse rarahaneng tsa ho kopanya kapa boholo ba likaroloana tse nyane.

Bakeng sa ores ea lead-zinc sulfide, hangata ho sebelisoa li-regrinding kapa tse mahoashe tsa concentrate, 'me mokhoa oa ho khutlisa ore ha o sebelisoe ka seoelo.Mokhahlelong oa karohano, lead-zinc sulfide ore hangata e nka mokhoa oa ho phaphamala.Mekhoa e sebelisoang hona joale ea ho phaphamala e kenyelletsa: ts'ebetso ea pele ea ho phaphamala, ts'ebetso e tsoakiloeng ea ho phalla, joalo-joalo Ho phaella moo, ho itšetlehile ka mokhoa o tloaelehileng oa ho phalla ka ho toba, mekhoa e lekanang ea ho phaphamala, mekhoa e mahoashe le e ntle ea karohano, mekhoa ea ho phalla ha makala, joalo-joalo e boetse e ntlafalitsoe, tse khethiloeng haholo ho latela boholo ba tsona bo fapaneng le likamano tse kentsoeng.
