Ulwazi olujwayelekile ngamamaki e-ore
Ibanga le-ore libhekisela kokuqukethwe yizingxenye eziwusizo ku-ore.Ngokuvamile kuvezwa ngamaphesenti amaningi (%).Ngenxa yezinhlobo ezahlukene zamaminerali, izindlela zokuveza izinga le-ore nazo zihlukile.Izinsimbi eziningi zensimbi, njengensimbi, ithusi, umthofu, i-zinc nezinye izinsimbi, zivezwa ngephesenti elikhulu lokuqukethwe kwensimbi;izinga lamanye ama-ores ensimbi liboniswa ngamaphesenti amaningi ama-oxides awo, njenge-WO3, i-V2O5, njll.Ibanga lezinto ezisetshenziswa kakhulu zamaminerali angewona ezensimbi livezwa ngephesenti elikhulu lamaminerali awusizo noma izinhlanganisela, njenge-mica, i-asbestos, i-potash, i-alunite, njll.;izinga lensimbi eyigugu (njengegolide, iplatinamu) ngokuvamile ivezwa ngo-g/t ;Izinga lensimbi yedayimane eyinhloko ivezwa nge-mt/t (noma i-carat/ton, eqoshwe njenge-ct/t);izinga le-placer ore ngokuvamile livezwa ngamagremu ku-cubic centimeter ngayinye noma ikhilogremu nge-cubic meter ngayinye.
Inani lokusetshenziswa kwe-ore lihlobene eduze nebanga layo.Insimbi ingahlukaniswa ibe insimbi ecebile kanye nensimbi embi ngokwebanga.Isibonelo, uma insimbi inezinga elingaphezu kuka-50%, ibizwa ngokuthi insimbi enothile, futhi uma izinga libalelwa ku-30%, libizwa ngokuthi i-ore empofu.Ngaphansi kwezimo ezithile zobuchwepheshe nezomnotho, izinga lezimboni lensimbi elifanele ukumbiwa livamise ukucaciswa, okungukuthi, izinga eliphansi lezimboni.Imithetho yayo ihlobene eduze nosayizi wediphozithi, uhlobo lwe-ore, ukusetshenziswa okuphelele, ubuchwepheshe bokuncibilikisa kanye nokucubungula, njll. Isibonelo, insimbi yethusi ingambiwa uma ifinyelela ku-5% noma ngaphansi, futhi igolide le-vein lifinyelela ku-1 kuya ku-5 amagremu/ ithani.
Ibanga lezimboni libhekisela ezintweni eziwusizo ezinezinzuzo zezomnotho (okungenani zingaqinisekisa ukukhokhwa kwezindleko ezihlukahlukene njengokumba izimayini, ezokuthutha, ukucubungula kanye nokusetshenziswa) endaweni ethile yokugcina insimbi eyodwa kuphrojekthi eyodwa (njengokumba noma ukugenca imigodi). ).Okuqukethwe okumaphakathi okuphansi kwengxenye.Isetshenziselwa ukunquma izinga elibuyisekayo ngokwezomnotho noma elilinganiselwe ngokwezomnotho, okungukuthi, ibanga lapho inani lemali engenayo yensimbi embiwayo lilingana nazo zonke izindleko zokufakwayo futhi inzuzo yezimayini inguziro.Ibanga lezimboni lihlala lishintsha ngokuthuthuka kwezimo zezomnotho nezobuchwepheshe kanye nezinga lokufunwa.Isibonelo, kusukela ngekhulunyaka le-19 kuze kube manje (2011), izinga lezimboni zezimayini zethusi lehlile lisuka ku-10% laya ku-0.3%, futhi ngisho nebanga lezimboni leminye imigodi yethusi emikhulu evulekile lingehla liye ku-0. 2%.Ngaphezu kwalokho, amamaki ezimboni anamazinga ahlukene ezinhlobo ezahlukene zediphozithi yamaminerali.
