Isingeniso esifushane se-Tungsten Ore kanye ne-Concentrate

Njengoba sonke sazi, ama-tungsten carbides enziwa nge-tungsten ore. Futhi kulesi sihloko, ungabheka ulwazi oluthile mayelana ne-tungsten ore futhi ugxilise ingqondo. Lesi sihloko sizochaza ama-tungsten ores futhi sigxile kulesi sici esilandelayo:

1. Ukwethulwa kafushane kwe-tungsten ore nokugxilisa ingqondo;

2. Izinhlobo ezahlukene ze-tungsten ore kanye nokugxila

3. Ukusetshenziswa kwe-tungsten ore nokugxila

1. Isingeniso esifushane se-tungsten ore kanye nokugxila

Inani le-tungsten kuqweqwe lomhlaba lincane uma kuqhathaniswa. Kuze kube manje kunezinhlobo ezingu-20 zamaminerali e-tungsten atholakele, phakathi kwawo kuphela i-wolframite ne-scheelite engancibilika. U-80% we-tungsten ore yomhlaba wonke useChina, eRussia, eCanada naseVietnam. I-China iphethe u-82% we-tungsten yomhlaba wonke.

I-China tungsten ore inezinga eliphansi kanye nokwakheka okuyinkimbinkimbi. Ama-68.7% awo angama-scheelite, inani lawo laliphansi futhi izinga lawo laliphansi. Ama-20.9% awo yi-wolframite, ikhwalithi yawo yenani ibiphezulu. U-10.4% uyi-ore exubile, okuhlanganisa i-scheelite, i-wolframite, namanye amaminerali. Kunzima ukusuka. Ngemva kwezimayini ezingaphezu kwekhulu eziqhubekayo, i-wolframite yekhwalithi ephezulu isiphelile, futhi izinga le-scheelite liye laba phansi. Eminyakeni yamuva nje, intengo ye-tungsten ore kanye nokugxila iyanda.

2. Izinhlobo ezahlukene ze-tungsten ore kanye nokugxila

I-Wolframite ne-scheelite ingenziwa igxile ngokuchoboza, ukugaya ibhola, ukuhlukaniswa kwamandla adonsela phansi, ukuhlukaniswa kukagesi, ukuhlukaniswa kazibuthe, nezinye izinqubo. Ingxenye eyinhloko ye-tungsten concentrate yi-tungsten trioxide.

I-Wolframite igxilile

I-Wolframite, eyaziwa nangokuthi (Fe, Mn) WO4, insundu-mnyama, noma imnyama. Ukugxilisa ingqondo kwe-Wolframite kukhombisa ukucwebezela kwe-semi-metallic futhi kungokwesistimu ye-monoclinic. Ikristalu ivamise ukujiya ngemigqa ye-longitudinal kuyo. I-Wolframite ivame ukuhambisana nemithambo ye-quartz. Ngokwezindinganiso zokugxilisa ingqondo ze-tungsten yaseChina, i-wolframite ihlukaniswe yaba yi-wolframite special-I-2, i-wolframite special-I-1, i-wolframite grade I, i-wolframite grade II, ne-wolframite grade III.

I-Scheelite igxile

I-Scheelite, eyaziwa nangokuthi i-CaWO4, iqukethe cishe u-80% we-WO3, ngokuvamile ompunga-mhlophe, ngezinye izikhathi ophuzi kancane, onsomi okhanyayo, onsundu ngokukhanyayo, neminye imibala, ebonisa ukucwebezela kwedayimane noma ukucwebezela kwamafutha. Kuyisistimu ye-Crystal ye-tetragonal. Ifomu lekristalu livame ukuba ne-biconical, futhi ama-aggregates ngokuvamile amabhulokhi angajwayelekile angama-granular noma aminyene. I-Scheelite ivame ukuhambisana ne-molybdenite, i-galena, ne-sphalerite. Ngokwezinga lokugxilisa ingqondo lezwe lami le-tungsten, i-scheelite concentrate ihlukaniswe yaba i-scheelite-II-2 ne-scheelite-II-1.

3. Ukusetshenziswa kwe-tungsten concentrate

I-Tungsten concentrate iyisisetshenziswa esiyinhloko sokukhiqizwa kwayo yonke imikhiqizo ye-tungsten ochungechungeni lwezimboni olwalandela, futhi imikhiqizo yayo eqondile iyimpahla yokusetshenziswa eyinhloko yezinhlanganisela ze-tungsten njenge-ferrotungsten, i-sodium tungstate, i-ammonium para tungstate (APT), kanye ne-ammonium metatungstate ( AMT). I-Tungsten concentrate ingasetshenziselwa ukwakha i-tungsten trioxide (i-blue oxide, i-yellow oxide, i-purple oxide), eminye imikhiqizo ephakathi nendawo, ngisho nezingulube nezithasiselo zemithi, futhi okukhanga kakhulu ukuziphendukela kwemvelo okuqhubekayo kanye nemizamo esebenzayo yamazandulela afana ne-violet tungsten inkambu yamabhethri wamandla amasha.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
