Isiphetho:Izindleko ze-copper ore beneficiation ngokuvamile zihlala zisuka ku-$10 kuya ku-$50 nge-ton ye-ore echazwa, kuyilapho izindleko zamashejuli zihluke kakhulu kuye ngendawo yokusebenza nobunzima bayo.

I-Copper 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 orekuncike ezicabangeni eziningi kufaka phakathi izici ze-ore, ubuchwepheshe bokuzuza, isikali seplanti, nezimo zomnotho zendaweni. Izindleko zokusebenza ngokuvamile zihlala phakathi kwe$10 kuya ku-$50 ngentoniye-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-Copper Ore Beneficiation

I-kophiikhiqiza 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.
