I-nitrate yomthofu iyinhlanganisela yamakhemikhali esetshenziswa kakhulu ezimbonini ezahlukahlukene, kubandakanya nezimayini.Izakhiwo zayo eziguquguqukayo zikwenza kube ukukhetha okuhle kwezicelo eziningi emkhakheni wezimayini.Kulesi sihloko, sizohlola izizathu zokuthi kungani i-nitrate eholayo ikhethwa emisebenzini yezimayini kanye nezinzuzo zayo ezibalulekile.
Enye yezinhlelo zokusebenza eziyinhloko ze-nitrate yomthofu ezimayini indima yayo njengesiqalisi enqubweni yokuntanta.I-Flotation yindlela esetshenziselwa ukuhlukanisa amaminerali abalulekile edwaleni elizungezile.I-lead nitrate isebenza njenge-catalyst, ithuthukisa ukusebenza kahle kwale nqubo ngokuthuthukisa amanani okuthola kabusha kwezinsimbi eziyigugu njengesiliva negolide.Ukwengezwa kwe-nitrate yomthofu esitokisini se-flotation kusiza ekwakhekeni kwegwebu elizinzile, kube lula ukuhlukaniswa okukhethiwe kwamaminerali abalulekile ezinhlayiyeni ze-ganggue.
Ngaphezu kwalokho, i-nitrate yomthofu iphinde ivimbele imiphumela eyingozi ye-pyrite, eyaziwa nangokuthi "igolide lesiwula," enqubweni yokuntanta.I-pyrite ingaba nomthelela omubi ekubuyiseleni amaminerali abalulekile ngokudla umoya-mpilo owedlulele futhi ikhiqize izimo ezine-asidi.Ngokufaka i-oxidizing pyrite, i-nitrate eholayo iphikisana nethonya layo eliyingozi, okuholela ekusebenzeni okungcono kwe-flotation kanye nokwanda kokubuyiswa kwamaminerali.
I-nitrate yomthofu ayiphumeleli nje kuphela ekuthuthukiseni izinqubo zokuntanta kodwa futhi nasekucindezeleni ukwakheka kwezinhlayiya zegolide ezimelana ne-cyanide.Ekukhishweni kwegolide kusetshenziswa i-cyanide, ama-ore athile angase abe negolide eliphikisayo okunzima ukulikhipha.Kodwa-ke, ngokungeza i-nitrate yomthofu, ukwakheka kwezinhlanganisela ezinganyibiliki ezivimbela ukuncibilika kwegolide kungavinjelwa, ngaleyo ndlela kwandise amazinga okuthola igolide ngokuphawulekayo.
Izici eziqhumayo ze-nitrate yomthofu nazo zinenzuzo emisebenzini yezimayini.Iyingxenye ebalulekile yokwakhiwa kweziqhumane ezisetshenziselwa ukuqhumisa amatshe nensimbi.I-nitrate yomthofu isebenza njengesivamisi, okwenza iziqhumane zivuthe kalula futhi zilethe amandla adingekayo ukuze kubhidlizwe ukwakheka komhlaba.Ukuzinza nokuhambisana kwayo nezinye izinto kuyenza ibe ukukhetha okuthembekile nokuphephile ekusebenzeni kokuqhuma.
Ngaphezu kwalokho, i-lead nitrate ikhombisa ukuncibilika okuhle emanzini, okuwenza alungele ukusetshenziswa kwezimayini ezahlukahlukene.I-solubility yayo ivumela ukuphatha kalula kanye ne-dosing enembile ezinqubweni ezahlukene.Ukuncibilika okuthembekile kwe-nitrate yomthofu kuqinisekisa imiphumela engaguquki futhi kuncishiswe ukuhluka kwenqubo yokukhiqiza, okuholela ekusebenzeni kahle okuphelele kukonke.
Isici sokuphepha se-nitrate yomthofu siwukucatshangelwa okubalulekile kunoma yikuphi ukusebenza kwezimayini.Nakuba kubalulekile ukuphatha wonke amakhemikhali ngokucophelela, i-nitrate yomthofu iyazinza uma igcinwe futhi iphathwa ngendlela efanele.Ukuvutha kwayo okuphansi kanye nemvelo engasasebenzi ezintweni eziningi ezivamile kunomthelela ekusetshenzisweni kwayo okuphephile ezindaweni zezimayini.
Sengiphetha, i-lead nitrate inikeza izinzuzo eziningi ezikwenza kube ukukhetha okuhle kakhulu kwezicelo ezahlukahlukene zezimayini.Iqhaza laso njengesishoshovu se-flotation, ikhono layo lokubhekana nemiphumela elimazayo ye-pyrite, kanye nokusebenza kwayo kahle ekucindezeleni ukwakheka kwezinhlayiya zegolide ezimelana ne-cyanide kuyenza ibe yimpahla ebalulekile ezinqubweni zokukhishwa kwezimbiwa.Ukwengeza, izici zayo eziqhumayo, ukuncibilika emanzini, nokuphepha kukonke kunomthelela ekusetshenzisweni kwayo kabanzi embonini yezimayini.Ngokukhetha i-lead nitrate, abaqhubi bezimayini bangathuthukisa ukusebenza kahle, bathuthukise amazinga okubuyisela amaminerali, futhi baqinisekise izimo zokusebenza eziphephile.
