Impahla yokugqoka insimbi yegolide iyinhlanganisela ekhethekile yomshini esetshenziselwa ukukhipha igolide ensimbini yegolide, ikakhulukazi okuhlanganisa ukuchotshozwa, ukugaya, ukugreda, ukuntanta nezinye izinto zokusebenza. Inqubo yayo yakhelwe izinhlobo ezahlukene zetshe legolide le-vein, i-placer ore yegolide, njll., futhi amaminerali ahlukaniswa ngezinqubo ezinjengokuchotshozwa, ukugaya, ukuhlukaniswa kwamandla adonsela phansi kanye nokuntanta. Cishe u-80% wezitshalo zokukhetha igolide zisebenzisa i-flotation.

Imishini eyinhloko ihlanganisa umshini wokugaya umhlathi, umshini wokugaya ibhola, i-classifier, i-chute kanye nomshini we-flotation, njll. Phakathi kwazo, umshini wokugaya umhlathi usetshenziswa kabanzi ekugayweni okuqinile kwe-ore ngenxa yesakhiwo sayo esilula nokugcinwa kahle. Ukwehlukaniswa kwamandla adonsela phansi kusebenzisa umehluko ku-mineral density, futhi okokusebenza okuvame ukusetshenziswa kuhlanganisa i-chute, ithebula elinyakazayo, njll.; indlela ye-cyanidation ikhipha igolide ngokusebenzisa i-leaching, ukuwasha nezinye izinqubo. Inhlanganisela ye-centrifuge kanye netafula elinyakazayo lingathola kahle igolide, futhi insimbi ene-oxidized yezinga eliphansi ingelashwa ngenqubo yokucwiliswa kwenqwaba.

Ukuncibilikiswa kwegolide ngokuvamile kusebenzisa ukuncibilikiswa kwe-crucible ukukhiqiza igolide elixutshwe noma igolide eliqediwe. Inhlanganisela yezinto zokusebenza kanye nenqubo ibona uguquko olusebenzayo ukusuka ensimbini ukuya egolideni eliphelile. Ezinye izisetshenziswa zihlinzekwa ngu Isikrini se-TSX, Tianjin, China.
