Chromite ni igikoresho cy'ingenzi mu gushongesha ferroalloys, ibyuma bitanduye n'ibyuma by'agaciro. Inganda zikora ibyuma zikoresha kromiyumu ingana na 60%, ikoreshwa cyane cyane mu gukora ibyuma bitanduye, cyane cyane ibyuma bitanduye. Muri icyo gihe, kromite ikoreshwa cyane mu nganda zikora ibinyabutabire, inganda zikora imiti n'inganda z'urumuri.
Imitungo y'amabuye y'agaciro
Hari ubwoko burenga mirongo itanu bw'amabuye y'agaciro arimo chromium aboneka mu bidukikije, ariko amabuye y'agaciro yonyine arimo chromium afite agaciro k'inganda ni chromite, ari yo spinel (MgO, Al2O3), magnesia chromite (MgO, Cr2O3), na magnetite. (FeO, Fe2O3) n'ibindi bisubizo bikomeye. Mu buryo bw'imitekerereze, formula ya chromite ni FeO, Cr2O3, irimo 68% Cr2O3, 32% FeO, magnetic iri hagati, ubucucike 4.1 ~ 4.7g / cm3, ubukana bwa Mohs 5.5 ~ 6.5, kandi ishusho y'ubuso iri hagati y'umukara n'umukara wijimye. Amabuye y'agaciro ya Gangue agizwe ahanini na olivine, serpentine na pyroxene, rimwe na rimwe iherekejwe n'ibice bike bya vanadium, nickel, cobalt na molybdenum.
Ikoranabuhanga ryo Gutunganya
Umutungo wa chromite mu Bushinwa ni mubi cyane, ahanini wiganje muri Tibet, Xinjiang, Inner Mongolie, Gansu n'izindi ntara. Umutungo wa chromite wo mu mahanga ukwirakwira cyane cyane muri Afurika y'Epfo, mu Burusiya, muri Brezili, muri Leta Zunze Ubumwe za Amerika n'ahandi. Chromite ifite imiterere y'ubucucike bwinshi, magnetism yo hagati n'uduce duto twa kristu. Muri rusange, itondekwa hakoreshejwe ubucucike bw'amabuye y'agaciro, gutandukanya magnetic nabi, gutandukanya magnetic bikomeye hagati, gutandukanya imbaraga z'uburemere, guhindagurika kw'amazi n'ibindi bikorwa.
Uburyo bwo gukaraba
Ikwiriye amabuye y'agaciro ya chromite afite ubuziranenge bwinshi bw'amabuye y'agaciro kandi ahanini asa n'ibumba nk'imyanda. Ibikoresho byujuje ubuziranenge bishobora gutoranywa hakoreshejwe uburyo bworoshye bwo kumesa.
Gutandukanya amashanyarazi n'amakuru
Chromite ifite ubushobozi bwo hagati bwo gukurura ibintu kandi ishobora gutandukanywa no gutandukanya ibintu bikomeye bya rukuruzi byumye cyangwa bitose. Magnetite ijyanye nayo ibanza gutandukanywa na rukuruzi idakomeye, hanyuma igatandukana na rukuruzi hakoreshejwe CXJ cyangwa CFLJ, plate magnetic separator, vertical ring high gradient magnetic separator, nibindi. Ibikoresho bikora ubwiza bwumye n'ubutose, kandi bishobora guhitamo ibicuruzwa byujuje ibisabwa. Uburyo bwo gutandukanya rukuruzi bufite ibyiza byo kuba ubushobozi bunini bwo gutunganya ibintu no kwerekana ibimenyetso bihamye.
Ahantu ho gukoresha chromite muri Afurika y'Epfo
Gutondekanya itangazamakuru rikomeye
Uburemere bwihariye bwa chromite ni 4.1 ~ 4.7g / cm3, kandi uburemere bwihariye bw'amabuye y'agaciro ya gangue na silicate y'icyuma muri rusange ni 2.7 ~ 3.2g / cm3. Hifashishijwe itandukaniro ry'ubucucike hagati y'amabuye y'agaciro, spiral chute, jigging, shaking table, spiral beneficiation birashobora gukoreshwa. Imashini, centrifuges n'ibindi bikoresho biremereye byo gutondeka. Ubu buryo bubereye chromite ifite ingano ikomeye ya crystal, kandi uduce duto tworoshye dutakaza mu myanya y'inyuma.
Kureremba
Chromite ishobora gukoresha aside irike cyangwa amine zikusanya kugira ngo ihitemo ibintu byujuje ubuziranenge binyuze mu gukaraba no gukurura mu buryo bukwiye bwa pH. Ikwiriye chromites nziza n'izifite ubuziranenge.
Kunoza imiti
Kuri bimwe mu byuma bya chrome bigoye gutunganywa hakoreshejwe uburyo bwo kunoza imiterere y’ibintu, uburyo bwo kunoza imiterere y’ibintu—uburyo bwo guhuza imiterere y’ibintu cyangwa uburyo bumwe bwa shimi burakoreshwa. Uburyo bwo kunoza imiterere y’ibintu birimo: gutandukanya imiterere y’ibintu, gutandukanya imiterere y’ibintu, gutandukanya aside sulfuriki na aside chromique, gugabanya no gutandukanya aside sulfuriki n’ibindi.
Urugero rw'inyungu
Ingano ya Cr2O3 iri mu gice runaka cya chromite muri Afurika y'Epfo ni 24.80%. Ni ahantu ho kongera gutoranya imyanda. Ingano y'icyitegererezo ni -40 mesh kandi ingano y'uduce irangana. Chromite iboneka mu duce duto n'ibiri hafi hamwe n'ibirimo. Imyunyu ngugu y'ingenzi ni olivine na pyroxene, hamwe n'icyondo gito. Dukurikije imiterere y'ingero z'amabuye y'agaciro, inzira yo kuyabyaza umusaruro ishyirwaho nk'uruziga rurerure cyangwa ruhagaze rukora intambwe imwe.
Chromite nziza iri mu gice cy'inyuma cy'urukuta rw'ubutaka ikoresha uburyo bwo gutandukanya icyuma gihagaze cyangwa inzira yo gutandukanya icyuma gihagaze neza, ishobora guhitamo ibikoresho byujuje ibisabwa. Imyunyu ngugu irimo chromium iri mu gice cy'urukuta ni imyunyu ngugu myiza cyangwa izindi myunyungugu zidafite agaciro za chromium zageze ku bipimo byiza by'ubwiza.
