Kukondweretsa zinc Ore

Gawo la kutsogolera kwa migodi yotsogola nthawi zambiri imakhala yochepera 3%, ndipo zinc ndizochepera 10%. Kalasi wamba yotsogolera ndi zinc mu stew ores yaying'ono komanso yopanda pake ili pafupifupi 2.7% ndi 6%, pomwe migodi yayikulu imatha kufikira 3% ndi 10%. Kuphatikizika kwa gawo nthawi zambiri kumayambitsa 40-75%, zinc 1-10%, sulufule 16-20%, ndipo nthawi zambiri imakhala ndi zitsulo zolumikizira monga siliva, mkuwa, komanso kubituka; Kupanga kwa zinziri nthawi zambiri kumakhala zitsulo pafupifupi 50%, pafupifupi 30% sulsur, 5-14% chitsulo, 5-14%, komanso amakhala ndi chitsogozo chochepa, Coplium, mkuwa, ndi zitsulo zamtengo wapatali. Pakati pa migodi yapanyumba yotsogola ndi mabizinesi osankhidwa, 53% ali ndi gawo lokwanira kapena lofanana ndi 5%, 39%, ndi 8% ali ndi kalasi yoposa 10%. Nthawi zambiri, mtengo wokhazikika kwa migodi yayikulu ya zinc ndi kalasi yayikulu kuposa 10% pafupifupi 2000-2500 yoan / ton imachulukanso ngati kalasi yokhazikika.

Njira yamtengo wapatali ya zinc yokhazikika

Palibe njira yamtengo wapatali yosagwirizana ndi zinc amangoyang'ana ku China. Zonunkhira zambiri ndi migodi zimagwiritsa ntchito smm (Shanghai Notferous metfield Network) zinc mitengo yopanga ndalama kuti mudziwe mtengo wa zinziro; Kapenanso, mtengo wosinthira wa zinc amangoganiza za kuchulukitsa mtengo wa SMM zinc zamic ndi raio yokhazikika (mwachitsanzo 70%).

Zinc Statrate imawerengedwa mu mawonekedwe a proces (TC / RC), chifukwa chake mtengo wa zinc Zitsulo ndi kukonza ndalama (TC / RC) ndiye zinthu zomveka. TC / RC (Chithandizo ndi Kukonzanso zolipiritsa zopanga ma sector) amatanthauza njira zosinthira zinc kukhala zinc. TC ndi chindapusa chosintha kapena chindapusa choyenga, pomwe RC ndiye chindapusa choyenga. Kukonza ndalama (TC / RC) ndi mtengo woperekedwa ndi ogwira ntchito minda ndi amalonda ku SMLLER kuti ayendetse zinc. Kukonzanso chindapusa TC / RC kumatsimikiziridwa ndi zokambirana pakati pa migodi ndi kununkhira kumayambiriro kwa chaka chilichonse, mayiko a ku Norcland ndi North America nthawi zambiri amazindikira mtengo wa TC / RC. Ndalama zosintha zimakhala ndi mtengo wokhazikika wa zinc. Kusintha kwa mtengo woyandama ndikuwonetsetsa kuti kusintha kwa ndalama zolumikizidwa kumalumikizidwa ndi mtengo wa zinc. Msika wapabanja umagwiritsa ntchito njira yochotsera mtengo wokhazikika kuchokera pamtengo wa zinc kuti mupeze mtengo wazokhazikika kapena kukambirana kuti mudziwe mtengo wa zinzi.
