【Amakuru ku bucukuzi bw'amabuye y'agaciro】Gukoresha umutungo w'amabuye y'agaciro ya zahabu ni ngombwa

Gukoresha neza imiyoboro y'amabuye y'agaciro ni ijambo rigezweho mu rwego rw'ubucukuzi bw'amabuye y'agaciro mu myaka yashize, kandi ubushakashatsi ku ikoreshwa ry'imiyoboro y'izahabu nabwo bwakozwe. Birumvikana ko umusaruro w'imiyoboro y'izahabu mu gihugu cyanjye wageze kuri toni zirenga miliyari 1.5, ariko igipimo cy'ikoreshwa ry'umutungo w'agaciro kiri munsi ya 20%. Kuri ubu, uburyo bwiza bwo gushyira mu bikorwa uburyo bwo kujugunya imyanda mu miyoboro y'izahabu mu buryo bubiri: kuzuza munsi y'ubutaka no gukoresha umutungo. Uburyo gakondo bwo kuzuza izahabu mu birombe ni ukuzuza imiyoboro y'amabuye y'agaciro mu mwobo, mu gihe imiyoboro y'amabuye y'agaciro irundanijwe mu kidendezi cy'amabuye y'agaciro. Kubera ko ubusanzwe ingano y'amabuye y'agaciro ari make, kugira ngo haboneke umutungo wa zahabu mwinshi, ubusanzwe ni ngombwa gukora ibikorwa byo gusya. Kubwibyo, imiyoboro y'amabuye y'agaciro irimo byinshi, mu gihe imiyoboro y'amabuye y'agaciro iba mike, kandi imiyoboro y'amabuye y'agaciro ni yo yonyine yuzura munsi y'ubutaka. , ntibishoboka kugabanya imyanda ikomeye no kugabanya ubushobozi bwo kubika ububiko bw'ibidendezi by'amabuye y'agaciro. Gufata ibidendezi by'amazi biracyasaba ubutaka bwinshi kandi byangiza ibidukikije. Gutabwa kw'amabuye y'agaciro byabaye ikintu gikomeye kibangamira iterambere rirambye ry'ubukungu bw'ibirombe bya zahabu.

Ku ya 10 Gashyantare 2022, Minisiteri y'Inganda n'Ikoranabuhanga mu Itangazamakuru, 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 bashyize ahagaragara ku bufatanye "Ku icapiro no Gukwirakwiza Kwihutisha Iterambere ry'Umutungo w'Inganda". "Itangazo ku Gahunda yo Gushyira mu Bikorwa Gahunda yo Gukoresha mu Buryo Bwuzuye" risaba ko mu 2025, imbaraga zo gukora imyanda ikomeye mu nganda mu nganda z'ingenzi nk'ibyuma n'ibyuma, ibyuma bidakoresha feri, n'inganda zikora imiti mu gihugu cyanjye zizagabanuka, urwego rw'imikoreshereze yuzuye y'imyanda ikomeye mu nganda ruzaba rwazamutse cyane, inganda zikoresha umutungo kamere zizakomeza gutera imbere mu buryo buzira umuze, kandi umutungo kamere mu nganda uzakoreshwa mu buryo bwuzuye. Imikorere myiza yazamutse cyane, kandi igipimo cy'imikoreshereze yuzuye y'imyanda ikomeye mu nganda kizagera kuri 57%. Kubwibyo, ikoreshwa ry'umutungo kamere w'ibishushanyo mbonera bya zahabu ni ngombwa.

Laboratwari y’ingenzi ya Sino-Ubudage ishinzwe amashanyarazi ya Magnetoelectricity and Intelligent Mineral Processing ya Huate Company ikora igerageza ryinshi ryo kunoza imiterere y’amabuye y’agaciro mu gace ka Yantai. Ibice by’ingenzi by’amabuye y’agaciro ya zahabu ni amabuye y’agaciro nka quartz, feldspar na calcite, hamwe n’ingano ntoya y’icyuma, icyuma cya magnetic, oxide y’icyuma, oxide ya titaniyumu, silicate y’icyuma, sulfide y’icyuma n’indi myanda. Ingano y’uduce tw’amabuye y’agaciro ya zahabu muri rusange ni 200 mesh 50-70%, ingano y’uduce irangana, kandi irimo agace gato k’icyondo gito. Ingano nyamukuru ya Fe2O3 ni 1-3%, TiO2 ni 0.1-0.3%, CaO ni 0.12-1.0%, kandi umweru w’uduce tw’agaciro twa zahabu ni 5-20%. Hari itandukaniro mu miterere y’uduce tw’agaciro twakozwe n’ibice bitandukanye. Hari imiterere y’ibimera ifite SiO2 nyinshi, cyangwa irimo spodumene, sericite, nibindi. Inyinshi muri zo ziba mu bwoko bwa pegmatite bwo mu bwoko bwa feldspar-quartz, bufite agaciro gakomeye ko kongera gukoreshwa.

Huate Company yavumbuye inzira yo gukusanya umusaruro uva mu "gutandukanya imbaraga za magnetic-gravity", kandi yabonye uburenganzira bwo kuvumbura patenti muri Nzeri 2020. Ibikubiye muri patenti bivuga ku "buryo busesuye bwo gukoresha zahabu irimo zahabu, icyuma na feldspar. Kuri ubu, inganda zirenga icumi nini zarakoreshejwe mu nganda nini i Yantai, Shandong, nini muri zo ishobora gutunganya toni 8.000 z'ingufu za zahabu ku munsi. Muri ubu buryo, ibikoresho bigezweho byo gukusanya umusaruro nka vibrating screen, spiral chute, shaking table, drum magnetic separator, wet strong magnetic plate magnetic separator, vertical ring high gradient magnetic separator, na electromagnetic slurry magnetic separator birakoreshwa hamwe. Mu gihe haboneka feldspar concentrate nziza cyane mu ingufu, ibicuruzwa by'agaciro nka magnetite, amabuye y'agaciro afite zahabu, sima, n'ibikoresho fatizo byo gukora amatafari nabyo biraboneka kugira ngo hakoreshwe neza ingufu za zahabu kandi nta gusohora zahabu mu buryo bwose.

Imashini itandukanya amashanyarazi ifite uruziga rurerure rw'impeta ihagaze n'imashini igabanya amashanyarazi ifite amashanyarazi menshi cyane ikoreshwa mu mushinga wo gushushanya ibyuma bya zahabu.
