Embonini yokucubungula amaminerali, isigaba sokugaya yisifunda esibalulekile esinotshalomali olukhulu kanye nokusetshenziswa kwamandla.Isigaba sokugaya silawula ukushintshwa okusanhlamvu kukho konke ukugeleza kokucubungula izimbiwa, okunomthelela omkhulu ezingeni lokubuyisela kanye nezinga lokukhiqiza.Ngakho-ke, umbuzo ogxiliwe wokunciphisa izindleko kanye nokuthuthukisa izinga lokukhiqiza ngaphansi kwezinga elithile lenhlawulo yokugaya.
Kunezinhlobo ezimbili zendlela yokugaya, ukugaya okuvula i-circuit kanye nokugaya okuvaliwe.Yiziphi izici zalezi zindlela ezimbili zokugaya?Iyiphi indlela yokugaya engabona ukusetshenziswa okuphezulu futhi ithuthukise izinga lokukhiqiza?Ezigabeni ezilandelayo, sizophendula le mibuzo.
Imininingwane yezindlela ezimbili zokugaya
Ukugaya okuvula isifunda ukuthi, ekusebenzeni kokugaya, impahla ifakwa esigayweni futhi ikhishwe ngemva kokugaya, ngqo esigayweni esilandelayo noma inqubo elandelayo.
Izinzuzo zokuvula-ukugaya umjikelezo ukugeleza okulula kokucubungula kanye nezindleko eziphansi zokutshala izimali.Nakuba ukungalungi izinga lokukhiqiza eliphansi kanye nokusetshenziswa kwamandla okukhulu.
Ukugaywa okuvalekile kungukuthi, emsebenzini wokugaya, insimbi ifakwa emshinini ukuze ihlukaniswe ngemva kokugaya, futhi insimbi engafanelekile ibuyiselwa emshinini ukuze igaywe kabusha, futhi insimbi efanelekayo ithunyelwa esigabeni esilandelayo.
Izinzuzo eziyinhloko ze-circuit-grinding evaliwe yizinga eliphezulu lokuchotshozwa, futhi izinga lokukhiqiza liphakeme.Ngesikhathi esifanayo, umjikelezo ovaliwe unezinga elikhulu lokukhiqiza.Kodwa-ke okubi ukuthi ukukhiqizwa komjikelezo ovaliwe kuyinkimbinkimbi kakhulu, futhi kubiza ngaphezu kokugaya okuvulekile.
Izinto ezingavumelani zigaywa ngokuphindaphindiwe esigabeni sokugaya esivaliwe kuze kufinyelelwe usayizi wezinhlayiyana ezifanele.Lapho ukugaya, amaminerali amaningi angathuthwa emishini yokugaya, ukuze amandla omshini webhola asetshenziswe ngangokunokwenzeka, athuthukise ukusebenza kahle kokusetshenziswa kwemishini yokugaya, ukuze kuthuthukiswe ukusebenza kahle kokukhiqizwa kwemishini yokugaya.
Imishini yezindlela ezimbili zokugaya
Ekukhetheni imishini yokugaya, umshini wokugaya ibhola awunalo ikhono lokulawula usayizi wezinhlayiyana.Kukhona okusanhlamvu okufanelekile okufanelekile kanye nezinhlamvu ezingafanelekile zama-coarse ku-drainage ye-ore, engafaneleki umshini wokugaya ovulekile.I-Rob Mill iphambene, ukuba khona kwezinduku zensimbi phakathi kwebhulokhi ewugqinsi kuzoqale kuphuke, ukuya phezulu kwezinduku zensimbi njengenombolo ye-grille, izinto ezicolekile zingadlula igebe phakathi kwezinsimbi zensimbi.Ngakho-ke, umshini wokugaya unamandla okulawula usayizi wezinhlayiyana futhi ungasetshenziswa njengemishini yokugaya evulekile.
Nakuba isigayo sebhola singenalo ikhono lokulawula usayizi wezinhlayiyana ngokwazo, singalawula usayizi wezinhlayiyana ngosizo lwemishini yokuhlukanisa.Isigayo sizokhipha insimbi emshinini wokuhlukanisa.Izinto ezinhle ezifanelekayo zingena esigabeni esilandelayo ngomjikelezo wokugaya.Ngakho-ke, ukugaya-circuit ukugaya okungafanelekile impahla emahhadla angase adlule esigayweni izikhathi eziningana, kumele umhlabathi kuya ofanelekayo kuyizinhlayiyana usayizi kungenziwa akhishwe imishini ngokwezigaba.Cishe akukho mkhawulo kumishini yokugaya engakhethwa esigabeni sokugaya esivaliwe.
Ukusetshenziswa kwezindlela ezimbili zokugaya
Ngokusho kwezinhlobo ezahlukene zamaminerali, izici, kanye nezidingo ezahlukene zokucubungula ukugeleza, izidingo zokugaya ukucolisa zihlukile.Isimo sezinto ezinokwakheka okuhlukile ezifinyelela izinga elifanele lokuhlukaniswa naso asifani.
Ekugayeni okuvalekile, izinto ezibuyiselwe kumshini wokugaya cishe zifaneleka.Ukugaya kabusha okuncane kuphela kungaba umkhiqizo ofanelekayo, futhi ukwanda kwezinto emshinini wokugaya, izinto ngokusebenzisa isigayo ngokushesha, isikhathi sokugaya sifinyelelwe.Ngakho-ke, ukugaya okuvaliwe okujikelezayo kunezici zokukhiqiza okuphezulu, izinga elikhanyayo lokuchotshozwa ngokweqile, ukusabalalisa okuhle nokufana kosayizi wezinhlayiyana.Ngokuvamile, isitshalo se-flotation kanye nesitshalo sokuhlukanisa kazibuthe ngokuvamile sisebenzisa inqubo yokugaya evaliwe.
I-open-circuit grinding ifanele ukugaya kokuqala.Impahla ekhishwa engxenyeni ethile yesigayo ingena kwezinye izinto zokugaya bese iyagaywa (cono).Ngale ndlela, ingxenye yokuqala yokugaya induku inesilinganiso esincane sokuchotshozwa namandla okukhiqiza aphezulu, futhi inqubo ilula.
Ukufingqa, kungabonakala ukuthi ukukhethwa kwemodi yokugaya kuyinkimbinkimbi, edinga ukucatshangelwa ezicini eziningi ezifana nezakhiwo ezibonakalayo, izindleko zokutshala izimali, nezinqubo zobuchwepheshe.Kuphakanyiswa ukuthi abanikazi bezimayini baxhumane nabakhiqizi bemishini yokucubungula abaneziqu zokuklama imayini ukuze bagweme ukulahlekelwa kwezomnotho.
