Khopolo ea Flotation ea Ore ea Khauta

Khauta e atisa ho hlahisoa sebakeng sa mahala ho ores.Liminerale tse tloaelehileng haholo ke khauta ea tlhaho le lirafshoa tsa khauta tsa silevera.Kaofela ha tsona li na le mokhoa o motle oa ho phaphamala, kahoo ho phaphamala ke o mong oa mekhoa ea bohlokoa bakeng sa ho lokisa mabenyane a khauta.Hangata khauta e kopantsoe le liminerale tse ngata tsa sulfide.Symbiotic, haholo-holo hangata e lumellanang le pyrite, kahoo ho phaphamala ha khauta le ho phaphamala ha tšepe ea sulfide e kang pyrite e nang le khauta li amana haufi-ufi.Mekhoa ea ho phaphamala ea li-concentrators tse 'maloa tseo re tla li hlahisa ka tlase ke lirafshoa tsa khauta tseo ho tsona liminerale tsa khauta le sulfide li phelang hammoho.

Ho itšetlehile ka mofuta le bongata ba sulfide, mekhoa e latelang ea phekolo e ka khethoa.
① Ha sulfide ka har'a ore haholo-holo e le pyrite, 'me ho se na li-sulfide tse ling tse boima tsa tšepe,' me khauta e fumaneha haholo ka likaroloana tse mahareng le tse ntle le symbiotic le iron sulfide.Ores e joalo e phaphamala ho hlahisa likhau tsa khauta tsa sulfide, 'me li-concentrate tsa flotation li ntan'o ts'oaroa ke moea oa sepakapaka, ka hona ho qoba kalafo ea cyanidation ea ore kaofela.The flotation concentrate e ka boela ea romeloa fekthering ea pyrometallurgy bakeng sa ho sebetsa.Ha khauta e le ka sebopeho sa likaroloana tsa submicroscopic le pyrite, phello e tobileng ea cyanide leaching ea concentrate ha e ntle, 'me e tlameha ho halikisoa ho arola likaroloana tsa khauta ebe e tšeloa ke sepakapaka.

② Ha li-sulfide tse ka har'a tšepe li na le chalcopyrite, sphalerite, le galena e nyenyane ho phaella ho iron sulfide, khauta e lumellana le pyrite le li-sulfide tsena tse boima.Kakaretso ea moralo oa phekolo: Ho ea ka mokhoa o tloaelehileng le tsamaiso ea lik'hemik'hale ea tšepe ea sulfide e se nang ferrous, tšoara le ho khetha concentrate e lumellanang.The concentrate e romeloa ho smelter bakeng sa ho sebetsa.Khauta e kenya koporo kapa loto (hangata e tsepamisitsoe haholo ke koporo) e tsepamisitse maikutlo 'me e fumanoa nakong ea ho qhibiliha.Karolo eo khauta le iron sulfide li kopanang ho eona e ka phaphamala ho fumana iron sulfide concentrate, eo ka nako eo e ka fumanoang ka ho besoa le ho tsoa moeeng.

③ Ha ho na le li-sulfide tse kotsi moeeng ka har'a ore, joalo ka arsenic, antimony, le sulfide ea sulfide, concentrate ea sulfide e fumanoang ka ho phaphamala e tlameha ho chesoa ho chesa arsenic, sulfide le lisebelisoa tse ling ka har'a concentrate hore e be bonolo. , sila slag hape 'me u sebelise pene ho tlosa li-oxide tsa tšepe tse sa tsitsang.

④ Ha karolo ea khauta ka har'a ore e le sebakeng se lokolohileng, karolo ea khauta e lumellana le sulfide, 'me karolo ea likaroloana tsa khauta e kenngoa ka har'a liminerale tsa gangue.Ores e joalo e tlameha ho khutlisoa ka karohano ea matla a khoheli ho khutlisa khauta e sa lefelloeng, le ho khutlisa symbiosis le sulfide ka flotation Bakeng sa khauta, ho ipapisitse le lintlha tsa khauta tsa mehatla ea flotation, hoa hlokahala ho nahana hore na ho sebelisoa leaching ea lik'hemik'hale.The flotation concentrate e ka siloa ka bokhabane ebe joale ea chesoa ka ho otloloha, kapa masalla a cheleng a ka siloa hantle ka mor'a hore a chesoe ebe a chesoa.
