Isingeniso
Emkhakheni wokucubungula amaminerali, ukusebenza kahle nokusebenza kahle kwemisebenzi yokugqoka i-ore kubaluleke kakhulu. Enye yentuthuko ebaluleke kakhulu kulo mkhakha ukusetshenziswa kwe Isihlukanisi Sezigubhu Ezimanzi . Lobu buchwepheshe buguqule izinqubo zokuhlukanisa ngokunikeza isixazululo esiqinile sokukhipha izinhlayiya kazibuthe engxubeni ye-ores. Ukuqonda izinzuzo zokuhlukanisa izigubhu ezimanzi azigcini nje ngokuthuthukisa ukutholakala kwamaminerali kodwa futhi kunomthelela ekongeni izindleko kanye nokusimama kwemvelo.
Izimiso Zokuhlukaniswa Kwezigqoko Ezimanzi
Emnyombweni wokuhlukaniswa kwezigubhu ezimanzi kukhona isimiso sikazibuthe. Lezi zihlukanisi zisebenzisa umehluko wezakhiwo kazibuthe phakathi kwamaminerali ukuze kuzuzwe ukuhlukana. Empeleni, isihlukanisi sesigubhu esimanzi siqukethe isigubhu esizungezayo esicwiliswe ethangini. Isigubhu sifakwe izibuthe ezihlala njalo ezihlelwe ngephethini eshintshanayo ye-polarity. Njengoba udaka oluqukethe insimbi lugelezela ethangini, izinhlayiya zikazibuthe zikhangwa endaweni yesigubhu futhi ziyiswa endaweni yokukhipha, kuyilapho izinhlayiya ezingezona kazibuthe zidlula zingathinteki.
I-Magnetic Field Gradient kanye nokuqina
Ukusebenza kwesihlukanisi sesigubhu esimanzi sikazibuthe kunqunywa kakhulu yi-gradient yensimu kazibuthe nokuqina. Amasimu kazibuthe ane-gradient ephezulu abalulekile ekubambeni izinhlayiya ezinhle kazibuthe. Ukumiswa kozibuthe kanye nokwakheka kwesigubhu kudlala indima ebalulekile ekukhiqizeni indawo kazibuthe edingekayo.
