Ukunambitheka kwe-zinc ore okuholayo

Izinga le-lead ore ekhishwa ezimayini zomthofu ngokuvamile lingaphansi kuka-3%, kanti i-zinc ingaphansi kuka-10%.Isilinganiso sezinga lomthofu kanye ne-zinc ensimbi engaphekiwe yezimayini ze-lead-zinc ezincane neziphakathi silinganiselwa ku-2.7% no-6%, kuyilapho izimayini ezinkulu ezinothile zingafinyelela ku-3% no-10%.Ukwakheka kwe-concentrate ngokuvamile kuholela ku-40-75%, i-zinc 1-10%, isulfure 16-20%, futhi ngokuvamile iqukethe izinsimbi ezihlala ndawonye njengesiliva, ithusi, ne-bismuth;Ukwakheka kwe-zinc concentrate ngokuvamile kuba ngu-50% we-zinc, cishe u-30% sulphur, 5-14% wensimbi, futhi iqukethe amanani amancane omthofu, i-cadmium, ithusi, nezinsimbi eziyigugu.Phakathi kwamabhizinisi asekhaya asebenza ezimayini okuhola i-zinc kanye nokukhetha, angama-53% anebanga eliphelele elingaphansi noma elilingana no-5%, u-39% unebanga lika-5% -10%, kanti u-8% unebanga elingaphezu kuka-10%.Ngokuvamile, izindleko zokugxilisa ingqondo ezimayini ezinkulu ze-zinc ezinebanga elingaphezu kuka-10% zingaba ngu-2000-2500 yuan/ton, kanti nezindleko zokugxilisa ingqondo ye-zinc nazo ziyakhuphuka njengoba izinga lincipha.

Indlela yentengo ye-zinc concentrate

Okwamanje ayikho indlela yokubeka intengo ehlanganisiwe ye-zinc e-China.Izincibilikisi eziningi nezimayini zisebenzisa amanani e-SMM (i-Shanghai Nonferrous Metals Network) amanani e-zinc khipha imali yokucubungula ukuze kunqunywe inani lentengo le-zinc eligxilisiwe;Kungenjalo, intengo yokwenziwayo ye-zinc concentrate inganqunywa ngokuphindaphinda inani le-zinc ye-SMM ngesilinganiso esinqunyiwe (isb. 70%).

I-Zinc concentrate ibalwa ngendlela yezimali zokucubungula (TC/RC), ngakho-ke intengo ye-zinc metal kanye nezindleko zokucubungula (TC/RC) yizona zinto eziyinhloko ezithinta imali engenayo yezimayini nezincibilikisi.I-TC/RC (Izindleko zokwelapha kanye nokucwengisiswa kokugxilwa kokucubungula) ibhekisela ezindlekweni zokucubungula nokucwenga zokuguqula i-zinc igxilise ku-zinc ecolisisiwe.I-TC yimali yokucubungula noma imali yokucwenga, kuyilapho i-RC iyimali yokucwenga.Imali yokucubungula (TC/RC) yizindleko ezikhokhwa abavukuzi nabahwebi kubancibilikisi ukuze kucutshungulwe ukugxiliswa kwe-zinc ku-zinc ecolisisiwe.Imali yokucubungula i-TC/RC inqunywa izingxoxo phakathi kwezimayini nabancibilikisi ekuqaleni konyaka ngamunye, kuyilapho amazwe ase-Europe naseNyakatho Melika evame ukuhlangana ngoFebhuwari emhlanganweni waminyaka yonke we-AZA we-American Zinc Association ukuze anqume inani le-TC/RC.Imali yokucubungula iqukethe inani lesisekelo sensimbi ye-zinc engashintshi kanye nenani elishintshashintshayo likhuphuke likhuphuke ngokushintshashintsha kwentengo yensimbi.Ukulungiswa kwevelu elintantayo wukuqinisekisa ukuthi izinguquko ezindlekweni zokucubungula zivunyelaniswa nenani le-zinc.Imakethe yasekhaya ikakhulukazi isebenzisa indlela yokukhipha inani elingashintshi enanini le-zinc ukuze inqume inani le-concentrate noma izingxoxo ukuze kutholwe inani le-zinc ore.
