Gukoresha mu buryo bwuzuye imirizo ni ijambo rishyushye mu bucukuzi bw'amabuye y'agaciro mu myaka yashize, kandi ubushakashatsi ku mikoreshereze yuzuye y’imirizo ya zahabu nabwo bwarakozwe. Byumvikane ko umusaruro w’ubudozi bwa zahabu mu gihugu cyanjye wageze kuri toni zirenga miliyari 1.5, ariko igipimo cy’imikoreshereze yuzuye kiri munsi ya 20% .Ubu, inzira nziza yo kumenya guta zahabu nta myanda kandi itagira ingaruka. ubudozi bwanjye burimo inzira ebyiri: kuzuza munsi yubutaka no gukoresha umutungo.Uburyo busanzwe bwo kuzuza amabuye y'agaciro ya zahabu ni ukuzuza imirizo yuzuye ingano mu iriba, naho imirizo inoze neza irundarunda mu cyuzi cy’ubudozi.Kuko ibikubiye muri zahabu ubutare busanzwe buri hasi, kugirango hagabanuke kugura umutungo wa zahabu, mubisanzwe birakenewe gukora ibikorwa byo gusya. Kubwibyo, imirizo inoze neza irimo byinshi, mugihe imirizo yuzuye ingano ari mike, kandi imirizo yuzuye yuzuye yuzuye munsi yubutaka. , ntibishoboka kugabanya byimazeyo imyanda ikomeye no kugabanya ubushobozi bwo kubika ibyuzi byumurizo. Kugumana ibyuzi by’ubudozi biracyasaba ubutaka bwinshi kandi byangiza ibidukikije.Kujugunya imirizo ya zahabu byabaye ikintu gikomeye kibuza iterambere rirambye ry’ubukungu bw’amabuye y'agaciro.
Ku ya 10 Gashyantare 2022, Minisiteri y’inganda n’ikoranabuhanga mu itumanaho, Komisiyo y’igihugu ishinzwe iterambere n’ivugurura, Minisiteri y’ubumenyi n’ikoranabuhanga, Minisiteri y’imari, Minisiteri y’umutungo kamere, Minisiteri y’ibidukikije n’ibidukikije, Minisiteri y’ubucuruzi , hamwe n’ubuyobozi bwa Leta bw’imisoro bafatanije gusohora “Ku gucapa no gukwirakwiza byihutisha iterambere ry’umutungo w’inganda”. “Amatangazo kuri gahunda yo gushyira mu bikorwa ikoreshwa ryuzuye” arasaba ko mu 2025, ubukana bwo kubyara imyanda ikomeye mu nganda mu nganda zikomeye nk'icyuma n'ibyuma, ibyuma bitagira fer, n'inganda z’imiti mu gihugu cyanjye bizagabanuka, urwego rukoreshwa neza imyanda myinshi y’inganda izatezwa imbere ku buryo bugaragara, inganda zivugururwa zizakomeza gutera imbere mu buzima, kandi n’inganda zizakoreshwa byimazeyo. Imikorere yaratejwe imbere ku buryo bugaragara, kandi igipimo cy’imikoreshereze yuzuye y’imyanda myinshi y’inganda kizagera kuri 57% .Nuko rero, gukoresha umutungo w’umurizo wa zahabu ni ngombwa.
Laboratoire y'ingenzi y'Abashinwa n'Abadage ya Magnetoelectricity na Intelligent Mineral Processing ya Huate ikora ubushakashatsi bwinshi bw'inyungu ku murizo wa zahabu mu gace ka Yantai. Ibice byingenzi bigize imyunyu ngugu ya zahabu ni amabuye y'agaciro ya gangue nka quartz, feldspar na calcite, hamwe na bike bya mashini ya mashini, ibyuma bya magnetiki, icyuma cya okiside, okiside ya titanium, silikatike yicyuma, sulfide yicyuma nibindi byanduye. Ingano yubunini buringaniye bwa Ubudodo bwa zahabu muri rusange ni mesh 50-70%, ingano yingirakamaro irasa, kandi irimo umubare muto wibyondo byiza. Umwanda nyamukuru wa Fe2O3 ni 1-3%, TiO2 ni 0.1-0.3%, ibirimo CaO ni 0.12-1.0%, naho umweru wumurizo wa zahabu ni 5-20%. Hariho itandukaniro runaka mubigize imirizo ikorwa na concentrated zitandukanye. Ubudozi bumwe bufite ibintu byinshi bya SiO2, cyangwa birimo spodumene, serisite, nibindi byinshi muribi byubwoko bwa pegmatite ya feldspar-quartz, bifite agaciro gakomeye.
Isosiyete ya Huate yahimbye “magnetique itandukanya-gravity itandukanya” ihuriweho n’inyungu, kandi ibona uruhushya rwo guhanga muri Nzeri 2020. Ibirimo ipatanti ni “uburyo bwo gukoresha mu buryo bwuzuye imirizo ya zahabu irimo zahabu, ibyuma na feldspar.Ubu, birenze, birenze icumi mu nganda nini nini zakozwe mu nganda zakorewe i Yantai, muri Shandong, nini muri zo zishobora gutunganya toni 8000 z’umurizo wa zahabu ku munsi.Muri iki gikorwa, ibikoresho byunguka byunguka nka vibrasi ya ecran, chute spiral, ameza yo kunyeganyega, imashini itandukanya ingoma , icyuma gikomeye cya magnetiki itandukanya magnetiki, impeta ihagaritse impagarike ndende ya magnetiki itandukanya, hamwe na electromagnetic slurry magnetic itandukanya ikoreshwa hamwe. Mugihe habonetse feldspar yo mu rwego rwo hejuru yibanda kumurizo, ibicuruzwa bifite agaciro nka magnetite, amabuye y'agaciro ya zahabu, ibikoresho bya sima, nibikoresho fatizo byo kubumba amatafari nabyo byagaruwe kugirango hamenyekane neza imirizo ya zahabu kandi bigere no gusohora zeru muri byose -inzira.
Impeta ihagaritse cyane ya magnetiki itandukanya hamwe na electromagnetic slurry high gradient magnetic itandukanya ikoreshwa mumushinga wubudozi bwa zahabu
