I-China lelona lizwe linemfuno enkulu yobhedu.Imfuno yayo ibalelwa kwi-45% yemfuno epheleleyo yehlabathi.Abavelisi bemigodi yobhedu bahlala eJamani, eChile, eIndonesia naseKhanada ngokulandelelanayo.Kuthatha abasebenzi abaninzi ukukhupha ubhedu olusulungekileyo kwaye ludinga iinkqubo ezininzi zokulucokisa, nto leyo ibeka uxinzelelo olukhulu kwimo engqongileyo.Okwangoku, imigodi yobhedu ibethwe kanobom zizinto ezininzi, ezinjengogwayimbo lweengxabano zabasebenzi eChile kunye nokungabikho kombane eZambia naseCongo, ezithintele ukusetyenziswa kobhedu.Abasebenzi abaninzi kwimigodi yobhedu enkulu yaseChile bahlala kufuphi nomgodi wobhedu waseCujkammata, obala ngokubanzi isahlulo seshumi okanye isithathu seshumi seendleko ezipheleleyo kushishino lokucoca ubhedu ngenxa yemigodi eyingozi kakhulu , Ngoko ke ukusebenza kwemigodi ephantsi komhlaba kubiza ngaphezulu.
Kuyilo kunye nenkqubo yokuvelisa i-concentrator, ukuze kwandiswe ukuphinda kusetyenziswe izimbiwa eziluncedo kwii-ores ezikhethiweyo kunye nokunciphisa ukusetyenziswa kwamandla kwe-concentrator kangangoko kunokwenzeka, impembelelo yokusingqongileyo kunye nongcoliseko luyancitshiswa, kunye neenzuzo zoqoqosho kunye nezentlalo. ye-concentrator yandiswa Ukukhethwa kokutyumza, ukugaya, ukujikeleza kunye nezixhobo zokuxilisa kubaluleke kakhulu.Ukutyumza, inkqubo yokugaya ukusetyenziswa kwamandla kunye nokusetyenziswa kwentsimbi kubalelwa ngaphezu kwesiqingatha semveliso ye-concentrator, ngakumbi inkqubo yokusila, ukusetyenziswa kwamandla kwiyunithi nganye ephezulu kakhulu kunenkqubo yokutyumza, kubalwa ngaphezu kwe-85% yonke imisebenzi yokutyunyuzwa kwamaminerali, ukubalwa konyulo. isityalo se-30% ukuya kuma-60%.Ke ngoko, ukusetyenziswa kwenkqubo entsha yokutyunyuzwa, ukukhethwa kwezixhobo ezinkulu zokutyumza eziphezulu kunye nezinye iindlela zokuqinisa umsebenzi wokutyumza, ukunciphisa i-ore yokutyisa ubukhulu be-ore, kukuphucula ukusebenza kakuhle kokutyumza, ukunciphisa iindleko zokugqoka i-ore. indlela ebalulekileyo, kodwa uyilwe umxhamli kufuneka alandele kwaye aqwalasele isiseko kumgaqo.
Inkqubo yokutyumza yenkqubo yokutyumza yendabuko inobukhulu obukhulu be-particle kwaye kunzima ukuphumeza umgaqo wokulondoloza amandla wokutyumza ngakumbi kunye nokugaya okuncinci.Iimpawu zenkqubo zezi: ukusetyenziswa kwamandla aphezulu, inkqubo ende.Ngokubanzi, umsebenzi wokutyumza kufuna ukusetyenziswa iziqwenga ezimbini okanye ngaphezulu ezaphukileyo ukufumana ubungakanani imveliso efanelekileyo, oku kuya kubangela ukwanda kwenani iziqwenga izixhobo ukutyumza indawo plant ukwanda, phantse ukwandisa utyalo-mali eyinkunzi.Ke ngoko, inkqubo yoyilo usebenzisa izixhobo ezinkulu, eziphezulu zokutyumza yindlela yophuhliso lwenkqubo yokutyumza.
