Njengoba ukukhathazeka okusimeme okuthinta ukuguquka kwesimo sezulu kuyanda, environmentally friendly methods in the mining and mineral processing industries have become a major source of interest.
Intuthuko entsha ekusetshenzisweni kwamaminerali omile ishintsha ngokushesha izindlela ezimanzi, kanye ST Izinsiza kusebenza & ubuchwepheshe, a leader in ngokwahlukana electrostatic isenhlokweni yepakethe ngobuchule bayo obunqenqemeni.
I-ore yigama lokuthi kungaba yinsimbi yendabuko noma amaminerali aphethe insimbi noma idwala elenzelwe inzuzo. Ukucubungula amaminerali yisinyathelo sokuqala se-ore uma nje kuphuma emayini. Le nqubo ifaka ukulungiswa kwensimbi, ukugaya, nokugqoka insimbi, okwaziwa kakhulu ngokuthi yinzuzo.
Ukuzuza kwehlukanise izinhlayiya zamaminerali oreji eqeleni (ongaphakeme-value) amaminerali abazungezile ukuze kukhiqizwe ukugxilwa okwenziwe ngamaminerali awusizo.
Lokhu kwehlukaniswa kungenziwa ngokwenyama, ngokuhlukaniswa kwamandla adonsela phansi, ngokwahlukana electrostatic, and magnetic separation, noma ngamakhemikhali, usebenzisa i-froth flotation, ukuvuza, nokufaka ugesi. Amaminerali angasebenziseki, okuvame ukulahlwa emadamini, kuthiwa yi-tailing.
Ukuze uqonde izinzuzo zokucubungula amaminerali omile, kufanele uqale uqonde ukuthi yehluke kanjani kwezinye izindlela.
froth flotation ihlehlela emuva ngasekupheleni kwekhulu le-19 futhi kwakuyindlela yokuqala eyenziwe umkhakha wezimayini ukwehlukanisa amaminerali kunsimbi.
I-Froth Flotation, okusetshenziswa futhi ezimbonini zokuphinda zisetshenziswe kabusha nezokulashwa kwamanzi angcolile, isebenza ezimisweni zokuminyana kanye nasezakhiweni zamanzi ezinhlayiya zamaminerali. Ukwehlukaniswa kwenzeka lapho amaminerali emanzi kusixazululo samakhemikhali, okwenza ukuthi izinto zihlanganiswe ngokuya ngokuthi ngabe ziyi-hydrophobic (okuphindisela amanzi) noma i-hydrophilic (ukuheha amanzi).
I-froth flotation isebenzisa amanzi amaningi ahlanganiswe nama-chemical agents, iningi lazo elingabuyiseki. Uma selucubunguliwe kufanele lomiswe ngaphambi kokulethwa. Lokhu kusho ukuthi akuyona indlela enhle kakhulu yemvelo.
Ukuhlomula okomile ihlukanisa udaba lwezimbiwa ngokuya ngokwehluka kobukhulu balo, isimo, usayizi, ukubenyezela, isimo, amandla kagesi kanye / noma kazibuthe. Ukuhlukaniswa kweMagnetic and electrostatic / tribo-electrostatic kuwela kulesi sigaba. Njengoba igama lisho, isebenzisa okuncane, uma kukhona amanzi kune-froth flotation, ukunciphisa okuningi kokubi kokugaya okumanzi.
Electrodynamic futhi Electrostatic – are the main types of izihlukanisi electrostatic. These work in a similar manner, but differ in which forces are applied to particles, okuyi, ukukhanga kwe-electrostatic noma ubukhulu. Ukuhlukaniswa kwamandla adonsela phansi kusebenzisa amandla we-centrifugal aguqulelwe kumandla adonsela phansi we-ores ne-gangue ukuze kwehlukaniswe.
Ukwehlukaniswa kukaMaginethi kusebenza ngokuhambisa izinhlayiya kunkambu kazibuthe ukuze kwehlukaniswe i-gangue ne-ore esetshenziswayo.
Izinzuzo zokuzuza okwomile zibandakanya ukwanda komkhiqizo nokuphepha, ukusimama, nodoti onguziro. Ngaphezu kokuncipha kokusetshenziswa kwamanzi, this method has fewer production phases and uses less power and equipment.
Ukuqeda amanzi kususa nesidingo sezinqubo ezibizayo zokususa amanzi, kufaka phakathi ukumpompa, ukuhlolwa, ukuhlunga, futhi ukukhipha centrifuging.
Kutholakala e-Needham, Massachusetts, sidale isihlukanisi se-triboelectric esihlukanisa amaminerali ngokuthambekela kwawo kwe-tribocharging, okuyi, izinhlayiya ziphendula kanjani lapho zifakwa ngogesi ngokuthintana nensimu kagesi. Not only is it revolutionizing minerals processing, it’s also proven to be highly effective for ukudla & feed separation. When used to beneficiate flours, ukudla, amaprotheni ukugxilisa ingqondo, kanye nefayibha.
Okokusebenza kokuhlukanisa okomile okuhle kakhulu embonini, ungabheki ngaphezu kwe-ST Equipment & ubuchwepheshe LLC (STET). It is leading the way in the minerals separation industry. Esethu triboelectric separation beneficiates micron-size particles through a totally dry process. It requires no additional materials or drying time and reduces the carbon footprint.
Ngaphezu kwalokho, sisebenza njengomthombo oligugu kwabanye embonini yokucubungula izimbiwa. Imininingwane ochwepheshe bethu bezobuchwepheshe ukuze bafunde kabanzi.
