Indlela yokukhetha isihlukanisi samaminerali

Izihlukanisi zamaminerali zibalulekile ekucutshungulweni kwezimbiwa ngoba zihlukanisa kahle amaminerali ayigugu emikhiqizweni engadingeki. Ngaphandle kwalokho, isihlukanisi samaminerali ukusetshenziswa kwebhizinisi lakho kungathinta kakhulu ukusebenza kahle kanye nenzuzo yawo wonke umsebenzi.

Uma kubhekwa uhla olubanzi lwezihlukanisi emakethe, ukukhetha imishini efanelekile yebhizinisi lakho kungaba inselele. Umhlahlandlela wanamuhla uzoxoxa ngamathiphu okukhetha, okuhlanganisa usayizi wokuphakelayo nokwakheka, umthamo, ukusebenza kahle kokuhlukanisa, umthamo wokucubungula, kanye nosayizi omkhulu wokusanhlamvu ovunyelwe. Ngokucabangela lawa macebiso, ibhizinisi lakho lingenza isinqumo esinolwazi futhi ligweme ugibe olwenziwa amabhizinisi amaningi lapho kukhethwa izihlukanisi zamaminerali.

Usayizi wemakethe yemishini yezimayini yomhlaba wonke

Ngokusho kweGrand View Research, imakethe yezimayini yomhlaba wonke yaziswa kakhulu US $ 135 billion ngo-2022 futhi kulindeleke ukuthi ikhule ngezinga lokukhula elihlanganisiwe lonyaka (CAGR) lika-5.1% ukusuka ngo-2023 kuya ku-2030.

Phakathi kwezinto ezibalulekile zokukhula esikhathini sokubikezela ukwanda kokutshalwa kwezimali kanye nokwesekwa kukahulumeni kokusungulwa kwezimayini zedijithali. Ukwengeza, ukusebenzisa amathuluzi okumba athuthukisiwe futhi amasha kanye nobuchwepheshe kuye kwathuthukisa amamaki e-ore, ngaleyo ndlela kwandise ukuphila kwezimayini ezindala.

Amathiphu okukhetha izihlukanisi zamaminerali

Usayizi wokuphakelayo kanye nokwakheka

Usayizi wempahla yokuphakelayo kanye nokwakheka kuwukucatshangelwa okubalulekile lapho ukhetha isihlukanisi samaminerali. Lokhu kungenxa yokuthi usayizi wokuphakelayo kanye nokwakheka kungathinta kakhulu ukusebenza kwesihlukanisi samaminerali. 

Isibonelo, uma okuphakelayo ikakhulukazi kuqukethe izinhlayiya ezincane, kungase kudinge isihlukanisi esihlukile kunalapho okuphakelayo kwakhiwa izinhlayiya ezinkulu. Ukwengeza, ukukhetha kwesihlukanisi kungase kube nomthelela uma okokusebenza kokuphakelayo kuhuga kakhulu noma kufaka phakathi ukungcola.

Uhlobo lwamaminerali

Lokhu kusengenye ukucatshangelwa okubalulekile lapho ukhetha izihlukanisi zamaminerali. Amaminerali ahlukene anezinhlobonhlobo ezihlukahlukene, ngakho-ke isihlukanisi esicacisiwe siyadingeka ukuze kutholakale ukuhlukana okuphumelelayo.

Isibonelo, amaminerali kazibuthe afana ne-magnetite ne-hematite adinga isihlukanisi kazibuthe ukuze sifinyelele ukuhlukana. Ngakolunye uhlangothi, izinto ezingezona kazibuthe njengegolide neplatinamu zizodinga a ukuze kuzuzwe ukuhlukana okusebenzayo. Izihlukanisi zamaminerali ezingezona uzibuthe zihlanganisa izihlukanisi zamandla adonsela phansi kanye nezihlukanisi ezintantayo.

Ukucabangela uhlobo lwezinto zokwakha ngesikhathi sokukhetha imishini kuzosiza amabhizinisi ukuthi akhethe isihlukanisi esifanelekile sokusebenza kahle kwamaminerali kanye nenzuzo.

Ukusebenza kahle kokuhlukanisa

Isihlukanisi esisebenza kahle kakhulu sizosho ukuthi ibhizinisi lizothumela umkhiqizo ophezulu wezimbiwa ezibalulekile, ngaleyo ndlela linciphise inani lokumosha nokwandisa inzuzo. Ngesikhathi sokukhethwa, amabhizinisi kufanele acabangele uhlobo lwempahla kanye nesihlukanisi samaminerali ngoba kokubili kuyahambisana. Ezinye izihlukanisi zamaminerali zingase ziphumelele kakhulu kunezinye ohlotsheni oluthile lwamaminerali.

Icubungula umthamo

Amabhizinisi kufanele acabangele ukuthi kungakanani okukhiphayo isihlukanisi samaminerali esingasingatha ngempumelelo phakathi nesikhathi esishiwo, njengehora.

Ukukhetha isihlukanisi esinamandla okucubungula aphezulu kusho ukuthi ibhizinisi lithuthukisa ukusebenza kahle, okuholela emvuzweni ephezulu. Ngokuphambene, isihlukanisi samaminerali esinomthamo ophansi wokucubungula sizoletha ukungasebenzi kahle.

Ngakho-ke, khetha isihlukanisi samaminerali esihlangabezana nezidingo zebhizinisi.

Ubukhulu obuvunyelwe bosayizi wokusanhlamvu

Ubukhulu obuvunyelwe ubukhulu bungenye ukucatshangelwa okubalulekile lapho ukhetha isihlukanisi samaminerali. Lokhu kungenxa yezizathu ezimbili; okokuqala, uma izinhlayiya zinkulu kakhulu ukuze umshini uphathe, ukuhlukaniswa kuzokhipha okuphumayo ngokungcola okukhulayo noma imfucuza. Okwesibili, okuphambene nakho kuyiqiniso. Uma usayizi wokusanhlamvu weminerali mncane kakhulu, inqubo izoholela ekuhlukaniseni okungasebenzi kanye nokukhipha umkhiqizo ngokungcola okwandisiwe.

Izinhlobo zezihlukanisi zamaminerali

Izihlukanisi kazibuthe

Izihlukanisi kazibuthe asetshenziswa embonini yezimbiwa ukuze ahlukanise amaminerali angenamagnetic. 

Basebenzisa inkambu kazibuthe ukufeza ukuhlukana futhi bahlukaniswa ngezinhlobo ezintathu:

1. Isihlukanisi kazibuthe esibuthakathaka (isihlukanisi kazibuthe esinamandla aphansi)

2. Isihlukanisi kazibuthe esimaphakathi

3. Isihlukanisi kazibuthe esinamandla (isihlukanisi esinamandla kazibuthe)

buhle

- Idizayini eguquguqukayo futhi elula

- Inamandla futhi iyaphatheka

bawo

- Ukugcinwa okungaguquki kuyadingeka

Izihlukanisi zamandla adonsela phansi

Izihlukanisi zamandla adonsela phansi sebenzisa izici zezinhlayiyana ukuze kuzuzwe ukuhlukana. Izici zifaka usayizi wezinhlayiyana, umumo, nokuminyana. Ngosayizi olawulwayo nomumo, isihlukanisi samandla adonsela phansi singahlukanisa ingxube yezinhlayiyana eziyinkimbinkimbi.

buhle

- Ukusebenza kahle okuphezulu kanye nezindleko eziphansi zokusebenza

– Ihambisana nemvelo njengoba awekho amakhemikhali asetshenziswayo

- Elula futhi enokwethenjelwa

bawo

- Ayilungele izinhlayiya ezinosayizi abahlukahlukene

- Umthamo wokucubungula ophansi

Isihlukanisi se-Centrifugal

Lesi sisetshenziswa sisebenzisa amandla e-centrifugal ukuhlukanisa amaminerali ngokusekelwe kubuningi bawo. I isihlukanisi se-centrifugal ingakwazi ukuphatha ama-feed osayizi abahlukene, kuhlanganise nezinhlayiya ezinhle. 

buhle

- Ukusebenza kahle kokuhlukana okuphezulu

- Iyakwazi ukucubungula osayizi abahlukene bokudla

bawo

- Idizayini eyinkimbinkimbi nokusebenza

- Ukufakwa kwamandla okubalulekile kuyadingeka

Isiphetho

Ngalokhu okungenhla amathiphu wokukhetha abahlukanisi bamaminerali, amabhizinisi manje angenza izinqumo ezinolwazi futhi athenge izinto zokusebenza ezihambisana nesidingo sazo.
