Uvavanyo ngaphambiliUnyango lwesisombululoyinkqubo yokuhlola kwangaphambili yemveliso egqityiweyo njengoko ichaziwe kwiukufowunaInxalenye yokuzoba kunye nekhadi lenkqubo lomgangatho womphezulu kunye nobungakanani bangaphandle emva kokugqitywa kwenkqubo yokuqulunqa. Uhlolo oluthile kufuneka lunikele ingqalelo kule miba ilandelayo:

Inkangeleko kufuneka ikhululeke kwii-rocks, amabala omzimba, isikali se-oxide kunye namaqhina kumphezulu wonyango lobushushu.

②Iumzobo weski wokufaUya kubonisa eyona milinganiselo iphambili, indawo ezikhethekileyo, iinxalenye zecandelo lomnqamlezo, ubume kunye nendawo yemingxunya.
Ubungakanani kunye nokuchaneka kokufaukuxolelaUkuba nobushushu obuphawuweyo kufuneka bonise isibonelelo somatshini, ubuqhetseba obungaphezulu, ukuchaneka komgangatho, ukuchaneka kwendawo kunye nokuchaneka kokubumba, njl.

I-④inspearies ijonge ngokungacwangciswanga isixa semali engaphantsi komhlaba esekwe kwi-10% -20% ye-batch inombolo yokufa. Xa i-btch yokuzilawula idibana nemizobo, inokufaka inkqubo yokuhlola. Ukuxolela okuphelileyo ngaphambi kokucinywayo kufuneka kugcinwe ngokwahlukeneyo.

Ilizwi lemveliso egqityiweyo ngaphambi kokucinywa, ubeke iziqwenga ezi-1-2 ze-1-2 ze-SCRODS SCRAPs azinakusetyenziselwa isampulu), kunye nesampulu "kwiUKUZIPHATHA KAKHULU. Veza umahluko.

Emva kokuhlolwa, inani leemveliso ezigqityiweyo, inkunkuma echanekileyo, inkunkuma yokugqibela kunye nenkunkuma yokugqibela kunye nekhowudi yesiphene kufuneka zizaliswe ngokuchanekileyo kwikhadi elihamba nezakhiwo kwaye zisayinwe ngumhloli.
