Gukoresha mu buryo bwuzuye imirizo ni ijambo rishyushye mu bucukuzi bw'amabuye y'agaciro mu myaka yashize, kandi ubushakashatsi bwakozwe ku mikoreshereze yuzuye ya zahabu na bwo 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 bwo kuzuza ibimina bya zahabu ni ukuzuza imirizo yuzuye ingano mu iriba, mugihe imirizo inoze neza irundarunda mu cyuzi cy’ubudozi.Kuko ibirimo zahabu Ubusanzwe ubutare buri hasi, kugirango umuntu arusheho kubona umutungo wa zahabu, mubisanzwe birakenewe gukora ibikorwa byo gusya.Kubwibyo, umurizo mwiza-uringaniye urimo byinshi, mugihe umurizo wuzuye utubuto duto, kandi umurizo wuzuye wuzuye wuzuye mubutaka., ntibishoboka kugabanya cyane 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 bwa zahabu.
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. , n'Ubuyobozi bwa Leta bw'Imisoro bafatanije "Ku Gucapa no Gukwirakwiza Kwihutisha Umutungo w'Inganda"."Amatangazo kuri gahunda yo gushyira mu bikorwa ikoreshwa ryuzuye" arasaba ko mu 2025, ubukana bwo kubyara imyanda iva mu nganda mu nganda zikomeye nk'icyuma n'ibyuma, ibyuma bitagira fer, n'inganda za shimi mu gihugu cyanjye bizagabanuka, urwego rwo gukoresha neza imyanda myinshi y’inganda izatezwa imbere ku buryo bugaragara, inganda zivugururwa zizakomeza gutera imbere neza, kandi umutungo w’inganda uzakoreshwa neza.Imikorere yazamutse cyane, kandi igipimo cyuzuye cyo gukoresha imyanda myinshi yinganda zikomeye kizagera kuri 57% .Nuko rero, gukoresha umutungo wumurizo wa zahabu ni ngombwa.
Laboratoire y'ingenzi y'Abashinwa n'Abadage ya Magnetoelectricity na Intelligent Mineral Processing ya Huate ikora ubushakashatsi bwinshi bwo kugirira akamaro umurizo 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, okiside yicyuma, okiside ya titanium, icyuma cya silike, fer sulfide nibindi byanduye. Ingano yubunini bwurwego Ubudodo bwa zahabu muri rusange ni mesh 50-70%, ingano yingirakamaro irasa, kandi irimo ibyondo bike.Umwanda nyamukuru wa Fe2O3 ni 1-3%, TiO2 ni 0.1-0.3%, CaO ni 0.12-1.0%, naho umweru wumurizo wa zahabu ni 5-20%.Hano hari itandukaniro muburyo bwimirizo ikorwa nabantu benshi.Ubudozi bumwe bufite ibintu byinshi bya SiO2, cyangwa birimo spodumene, sericite, nibindi byinshi muribi bya feldspar-quartz ubwoko bwa pegmatite, bifite agaciro gakomeye.
Isosiyete ya Huate yahimbye “magnetique itandukanya-imbaraga-itandukanya imbaraga” ihuriweho n’inyungu, kandi ibona uruhushya rwo guhanga muri Nzeri 2020. Ibirimo ipatanti ni “uburyo bwo gukoresha neza imirizo ya zahabu irimo zahabu, ibyuma na feldspar.Ubu, birenze, birenze Ibikorwa icumi binini byinganda byakorewe i Yantai, muri Shandong, binini muri byo bishobora gutunganya toni 8000 zumurizo wa zahabu kumunsi.Muri iki gikorwa, ibikoresho byunguka bigezweho nka vibrasi ya ecran, chute spiral, ameza yo kunyeganyega, imashini itandukanya ingoma , itose ikomeye ya magnetiki itandukanya magnetiki, impeta ihagaritse hejuru ya magnetiki itandukanya, hamwe na electromagnetic slurry magnetic itandukanya ikoreshwa muguhuza.Mugihe habonetse feldspar nziza cyane yibirindiro, ibicuruzwa bifite agaciro nka magnetite, amabuye y'agaciro ya zahabu, ibikoresho bya sima, nibikoresho bibumba amatafari nabyo biragarurwa kugirango hamenyekane neza imirizo ya zahabu kandi bigere kuri zeru muri byose. Inzira.
Impeta ihagaritse cyane ya magnetiki itandukanya na electromagnetic slurry high gradient magnetic itandukanya ikoreshwa mumushinga wubudozi bwa zahabu
