Ulwazi olujwayelekile mayelana namabanga e-Ore
Ibanga le-ore libhekisela kokuqukethwe kwezakhi eziwusizo ku-ore. Ngokuvamile kuvezwe ngamaphesenti amaningi (%). Ngenxa yezinhlobo ezahlukene zamaminerali, izindlela zokuveza i-Ore grade nazo zehlukile. Iningi lama-ores wensimbi, njengensimbi, ithusi, ukuhola, i-zinc kanye namanye ama-ores, kuvezwa ngamaphesenti amaningi okuqukethwe kwe-metal element; Ibanga lenye i-ores yensimbi livezwa ngamaphesenti amaningi ama-oxides abo, anjenge-WO3, V2O5, njll; Ibanga lezinto ezimbi ezingezinhle kakhulu ezimbiwa ngamaminerali zivezwa ngamaphesenti amaningi amaminerali awusizo noma amakhompiyutha, njenge-mica, asbestos, potash, alunite, njll; ibanga lensimbi eyigugu (njengegolide, iplatinamu) i-ores ngokuvamile ivezwa ku-G / t; ibanga ledayimane eliyisisekelo ledayimane livezwa ku-MT / T (noma i-carat / ton, eliqoshwe njenge-CT / T); Ibanga le-Placer Ore livame ukuvezwa kumagremu nge-cubic centimeter noma kilogram ngemitha ye-cubic.
Inani lesicelo se-ore lihlobene kakhulu nebanga layo. I-Ore ingahlukaniswa ibe yi-ore ecebile ye-ore ne-ore empofu ngokuya ebangeni. Isibonelo, uma i-Iron Ore inebanga elingaphezu kwama-50%, ibizwa ngokuthi yi-ore ecebile, futhi uma ibanga licishe libe ngu-30%, libizwa ngokuthi yi-ore empofu. Ngaphansi kwezimo ezithile zezobuchwepheshe nezomnotho, ibanga lezimboni le-Ore likubiza izimayini livame ukucaciswa, okungukuthi, ibanga eliphansi lezimboni. Imithetho yayo ihlobene kakhulu nosayizi wediphozithi, ukusetshenziswa okuphelele, ukunqwabelana nokucubungula ubuchwepheshe, njll. Isibonelo, i-vein yegolide ifinyelela kuma-5% noma ama-5 amagremu / Ithoni.
Ibanga lezimboni lisho izinto eziwusizo ezinezinto eziwusizo zezomnotho (okungenani ziqinisekisa ukukhokha izindleko ezahlukahlukene ezinjengezimayini, zokuhamba, ukucubungula kanye nokusetshenziswa) ebhlokini elinikeziwe lephrojekthi eyodwa (njengokudonsa noma ukudonsa ). Okuqukethwe okuphansi kakhulu kwengxenye. Isetshenziselwa ukunquma ibanga elibuyiselwe ngokwezomnotho noma elinomnotho, okungukuthi, ibanga lapho inani lemali engenayo le-ore limayini lilingana nazo zonke izindleko zokufaka kanye nenzuzo yezimayini ziyize zero. Ibanga lezimboni lihlala lishintsha ngokuthuthukiswa kwezimo zezomnotho nezobuchwepheshe kanye nezinga lezidingo. Isibonelo, kusukela ngekhulu le-19 kuze kube manje (2011), ibanga lezimboni zezilwane zethusi selishiyile lisuka ku-10% liye ku-0,3%, futhi nebanga lezimboni lamadiphozithi aphezulu e-open-piture popper angahlehlela ku-0. 2%. Ngaphezu kwalokho, amamaki emboni anamazinga ahlukile ezinhlotsheni ezahlukahlukene zama-mineral deposits.
