Copper Ore Concentration

Feem ntau cov tooj liab muaj tsuas yog ib feem me me ntawm tooj liab. Cov seem ntawm cov ore muaj gangue tsis muaj nqi lag luam. Gangue los ntawm tooj liab mining feem ntau muaj silicate minerals thiab oxides. Qee lub sij hawm cov tailings tau rov qab los raws li cov cuab yeej siv los kho cov tooj liab tau zoo dua. Qhov nruab nrab qib ntawm tooj liab ore nyob rau hauv lub xyoo pua 21st yog qis dua 0.6% tooj liab, nrog ib feem ntawm kev lag luam ore minerals (xws li tooj liab) tsawg dua 2% ntawm tag nrho cov ntim ntawm pob zeb ore. Lub hom phiaj tseem ceeb hauv kev kho metallurgical ntawm ib qho ore yog kev sib cais ntawm ore minerals los ntawm gangue minerals nyob rau hauv lub pob zeb.

Thawj theem ntawm cov txheej txheem nyob rau hauv ib tug metallurgical kev kho mob Circuit Court yog raug sib tsoo los yog comminution, qhov twg lub pob zeb yog crushed los tsim me me hais (<100 μm) muaj xws li ib tug neeg cov ntxhia theem. Cov khoom no raug muab cais tawm kom tshem tawm gangue (pob zeb residues), tom qab ntawd ua raws li cov txheej txheem ntawm lub cev liberation ntawm ore minerals los ntawm pob zeb. Cov txheej txheem ntawm kev ywj pheej ntawm tooj liab ore nyob ntawm seb lawv puas yog oxide lossis sulfide ores.
Cov kauj ruam tom ntej nyob ntawm seb qhov xwm txheej ntawm cov ore uas muaj cov tooj liab thiab dab tsi yuav muab rho tawm. Rau oxide ores, ib qho txheej txheem hydrometallurgical liberation yog ib txwm ua, uas siv cov dej soluble ntawm cov ore minerals kom zoo dua ntawm cov nroj tsuag kho metallurgical. Rau sulfide ores, ob qho tib si theem nrab (supergene) thiab thawj (hypogene), froth flotation yog siv los cais lub cev ore los ntawm gangue. Rau tshwj xeeb haiv neeg tooj liab bearing ore lub cev los yog cov seem ntawm ore lub cev nplua nuj nyob rau hauv supergene haiv neeg tooj liab, cov ntxhia no tuaj yeem rov qab los ntawm lub voj voog yooj yim.
