Kukho izinto ezintathu zokusetyenziswa kweedrain zentonga:
1) Kwindawo yokwahlulahlula-hlula okanye ukwahlulahlulahlulahlulahlulahlula i-tungnetic tin ore kunye nezinye ii-ores zentsimbi, ii-rore ii-ores zihlala zisetyenziswa ukuze kuthintelwe ukwenzakala okubangelwe ngaphezulu -}}}}}}}}}}}}}}}}} ityhule.
2) Xa le - inkqubo yokugaya isetyenzisiwe, ukuba inqanaba lokuqala livela kwi-20 {{4} {isitovu se-ROD sisetyenziswa njengesixhobo sokuqala sokugaya, amandla okuvelisa siphezulu. Ngenxa yokuba umthwalo wentonga othile ubunzima obuthile bunendawo encinci engaphezulu kwebhola elayisha ubunzima obufanayo, imveliso kunye nokusebenza kakuhle kwe-rod milling iphantsi kunelo nqanaba lesibini lokugaya.
3) Kwezinye iimeko, inokutshintsha intloko emfutshane yentloko rusher yokutyumza. Xa iqhuba i-ores okanye i-ores enzima kakhulu (ingakumbi i-viscous ores), sebenzisa i-rod mills ukugaya i-19 {{8} {{8} {i-{8} {i-MM engcono i-ore. Xa umatshini kunye nesikrini zikwisekethe elivaliweyo, ubumbeko lulula, indleko iphantsi, kwaye ukususwa uthuli kwindawo yocweyo etyhefu kungena lula. Kwi-ores enzima, inokuba uqoqosho ngakumbi ukusebenzisa i-cone crusher yentloko kunye ne-sieve ukwenza isekethe evaliweyo. Uyilo, nokuba ulisebenzisa ibhola yebhola okanye i-rod yema yephulo lonyulo, kufuneka igqitywe ngokweemeko ezithile zokwenza izicwangciso kwaye uthelekise.
Ii-mills ze-rod zisetyenziswa ngokubanzi ngokwesinyithi kwaye {0}- imigodi yentsimbi, izinto ezingundoqo ngamanzi kunye nezinto zokwakha amasebe okutsala i-ores ezahlukeneyo okanye amatye.
