Summary: Inani lenani ye-copper ore beneficiation ngokujwayelekile liyaphendukela ku- kuze kufike ku- nge-ton ngayinye yomquba ovelele, kuyilapho izindleko zokutshala imali zihluke kakhulu ngokuya ngosayizi wefektri nokuphakama koyinkimbinkimbi....

I-I-kophi ore beneficiation iyinyathelo elibalulekile ekukhiqizeni insimbi ye-copper, ehlanganisa ukuhwezwa kwe-ore elenziwe ukuze kukhuphuke ukugxilisa kwe-copper ngaphambi kokuphola noma ukuthuthukiswa okwengeziwe. Ukuqonda isakhiwo sezindleko ze-copper ore beneficiation kubalulekile kumafektri, abatshali-zimali, kanye nabathintekayo ukuze bahlaziye ukuhweba kwegciwane, baphucule ukusebenza, futhi bathuthukise inzuzo.

Izindleko zokuthuthukiswa kwe-copper ore kuya khona ngezinto eziningi, kuhlanganise nezigaba zethusi, ubuchwepheshe bokuhlukanisa, usayizi wesitolo, nezimo zomnotho wendawo. Izindleko zokusebenza ngokuvamile zihlala phakathi kwe kuya ku- ngentoni ye-ore efakwe, kanti izindleko zezimali zihluka kakhulu kuye ngesisekelo sepulazi nobunzima.

Le ndatshana inikeza isithombe esiphelele sezici ezithonya izindleko zokuzuza i-copper ore, imikhawulo ejwayelekile yezindleko, nemicabango yokuphathwa kwezindleko.

Copper Ore Beneficiation Cost

1. Ukuhlanga ku-I-kophi Ore Beneficiation

I-kophi ikhiqiza kwezinye zezinto ezisetshenziswa kakhulu emhlabeni, kubalulekile ekuxhunyweni kwezimoto, ezokwakha, nezimboni eziningi. Ukuthuthukiswa kwekhu (copper ore beneficiation) kubhekisela ezinqubweni ezisetshenziselwa ukuhlukanisa imithombo ye-copper ewusizo emgqonyeni (imisebenzi) ethathwe emgodleni.

Inhloso enkulu ukuhlela i-concentrate enokhupha (copper) ophakeme, engase ibhujisheke ngempumelelo. Ukuhlobisa kuvame ukuhlotshaniswa nokushaywa, ukugaya, i-flotation, kanye nanoma ezinye izinyathelo ezifana nokudonsa noma ukuhlukaniswa kwe-magnetic, kuye ngesimo se-ore.
