Thepa ea Khauta ea Beneficiation - Ho notlolla Boleng bo Patehileng ba Ores ea Khauta

Lefatšeng le rarahaneng la meepo ea khauta, leeto la ho tloha mafikeng a tala, a sa makatseng ho ea ho a benyang, tšepe ea bohlokoa e tsamaisoa ke mohato o le mong oa bohlokoa: ho rua molemo.Thepa ea khauta ea ore beneficiatione eme e le motheo oa theknoloji oa tšebetso ena, e etselitsoeng ho arola khauta hantle ho matrix a eona, ho phahamisa litefiso tsa ho hlaphoheloa, le ho fokotsa tšusumetso ea tikoloho. Sehlopha sena sa mechini ha se taba ea ho ntša feela; e mabapi le tšebeliso e bohlale ea lisebelisoa.

Ts'ebetso ea beneficiation e qala ka ho sila le ho sila. Li-crushers tsa mehlahare, li-cone crushers, le li-mill mill li sebetsa ka mokhoa o ts'oanang ho fokotsa likarolo tse kholo tsa ore hore e be phofo e ntle, e lokollang likaroloana tsa khauta bakeng sa karohano e latelang. Leha ho le joalo, pelo ea molemo e itšetlehile ka mekhoa ea karohano. Mona, lisebelisoa tse kang li-centrifugal concentrators, joalo ka Knelson le Falcon concentrators, li sebelisa matla a khoheli a phahameng ho fumana le likaroloana tsa khauta tse ntlehali. Mechini ea Jig e arola lisebelisoa tse ipapisitseng le liphapang tsa boima ba 'mele, e theha phallo ea metsi e otlang, e lumellang khauta e boima ho lula.

Bakeng sa ores moo khauta e amahanngoang le liminerale tse ling, mechine ea flotation e kena. Ba hlahisa lik'hemik'hale tse etsang hore liminerale tse nang le khauta li be le hydrophobic, e leng se etsang hore li hokahane le lipululana tsa moea ebe li phaphamala ka holim'a metsi bakeng sa ho bokelloa. Ho sa le joalo, litafole tse tsukutloang li sebelisa ho sisinyeha ha metsi hantle le ho phalla ha metsi ho arola likaroloana ho ea ka ho teteana le boholo, ho hlahisa molatsoana oa khauta o teteaneng.

Molemo oa kajeno o feta karohano feela. Sistimi ea Carbon-in-Leach (CIL) le Carbon-in-Pulp (CIP) e emela mahlale a tsoetseng pele a papatso, moo khabone e kentsoeng e nkang khauta e qhibilihisitsoeng ho tsoa ho makhasi a cyanide. Litsamaiso tsena li tlatsitsoe ke lisebelisoa tsa ho hapa motlakase le ho qhibilihisa, tse qetellang ts'ebetso ka ho ntša khauta e hloekileng khaboneng e laetsoeng.

Boleng ba 'nete ba kajenolisebelisoa tsa ho thusa ka khautat e ipapisitse le kopanyo le bohlale ba eona. Sistimi ea taolo e ikemetseng e ntlafatsa paramente e 'ngoe le e' ngoe - ho tloha ho sekhahla sa phepelo le bophahamo ba metsi ho isa ho tekanyo ea lik'hemik'hale - e netefatsa ts'ebetso e phahameng haholo, e fokotsa tšebeliso ea matla, le ho fokotsa litšenyehelo tsa ts'ebetso. Mehleng ea li-ores tse ntseng li eketseha le melao e thata ea tikoloho, sesebelisoa sena se ntse se tsoela pele ho rarolla mathata a matala, joalo ka lipotoloho tse nang le metsi a koalehileng le lintho tse ling tse seng chefo.

Qetellong, lisebelisoa tsa ho rua molemo oa khauta ke senotlolo sa ho fetola li-marginal deposits hore e be likhoebo tse nang le phaello le ho atolosa bophelo ba merafo e teng. Ke mohale ea sa buuoeng ea tiisang hore tšepiso ea khauta lefatšeng ha e fumanehe feela, empa e phethahala ka botlalo le ka boikarabelo.
