I-IMC Kalium Ithembela e-Ellicott® Bucketwheel Dredge eMayini Ephansi Yezindleko Phosphate Imayini

Ngomthamo wonyaka wamathani amafushane angaphezu kwezigidi eziyishumi, IMC Kalium uphakathi kwabakhiqizi be-potash abahamba phambili nababiza kakhulu emhlabeni. Ngokuthengiswa okuphelele kwe-1997 kanye nemikhawulo ephelele yamaRandi ayizigidi ezingama-617.4 kanye namaRandi ayizigidi ezingama-237.7, ngokulandelana, uphiko lwebhizinisi lumele u-14% womthamo womhlaba.

Imikhiqizo ye-potash ye-IMC Kalium yathengiswa emazweni angaphezu kwama-20 ngonyaka ka-1997. IChina yiyona eyayiyikhasimende elikhulu kunawo wonke elithumela emazweni angaphandle, kanti ukuthengiswa kwasolwandle kwaba ngu-18% wokuthunyelwa kweKalium phakathi nonyaka. Ukuthunyelwa kwezolimo zase-US nabasebenzisi bezimboni kufinyelele kuma-55% no-13%, ngokulandelana. Ukusetshenziswa kwezolimo nezimboni zaseCanada kube ne-4% yokuthunyelwa okuphelele.

I-IMC Kalium isebenza ezimayini ezinhlanu eCanada kanti ezimayini ezintathu e-US IMC Kalium ichaza isisombululo sayo njenge-Belle Plaine, eSaskatchewan Canada. Ikhiqiza ubumsulwa obuphezulu be-potate emhlophe ye-potash ikakhulukazi ezimakethe zezimboni.

Ukuthola kabusha i-potash, imayini yeBelle Plaine isebenzisa i-Ellicott® I-B-490 dedgewheel dredge esebenza ngogesi esebenza ngokuthembekile iminyaka.

I-IMC Kaliumthruse ukusetshenziswa kwamakhompiyutha alawulwa ngamakhompiyutha kanye namasu wokukhipha amakristalu.

Ngaleso sikhathi, isixazululo sifakwa epayipini lokupholisa le-130-acre lapho okwengezwa khona amakristali futhi umkhiqizo owumphumela uyatholakala kabusha nge-Ellicott® ukugoba okuntantayo. I-potash ekhanyisiwe inamanzi, yomisiwe futhi ikalwa.

Umkhiqizo I-IMC Kalium yenza imikhiqizo eminingi ehlukahlukene ye-potash, eminye yayo ngenqubo enelungelo lobunikazi. Konke kuqala ngokuchoboza i-ore evele ibe zinhlayiya ngazinye ze-potash nosawoti ngayinye engaphansi kwe-3 / 8 intshi. I-ore echotshoziwe ihlanganiswa ne-brine, isisombululo esinosawoti, bese idonswa ezikrinini ze-10-mesh, ezingaba ngosayizi bezikrini zasendlini. Izinhlayiya ezinkulu eziphambukiswe yisikrini ziya ku-Hard Media. Izinhlayiya ezincane ziyehla futhi ziye kuFlotation. Esimweni segumbi lekhompiyutha elilawulwa ngekhompiyutha eliphakathi nendawo, ukuguquguquka kokushintshashintshashintshi ekusetshenzisweni komhlaba kuhlala kugadwe njalo ukuqinisekisa imikhiqizo esezingeni.

IMedia Media Kule nqubo, izinhlayiya ezinkulu ezikhethiwe ezingabekwanga ze-potash nosawoti zihlanganiswa ne-brine ne-magnetite. Ukudonswa okuqondile kwalesi sixazululo esindayo semidiya kungukuthi i-potash izothantazela phezulu futhi usawoti nokungcola kuzowela phansi. I-potash elintantayo, noma izinhlayiya zobukhulu obuhlanganayo, ziyagezwa, zithweswe isikhumba bese zomile. Ezinye izinhlayiya, ezibizwa ngokuthi ama-middlings, azihlukaniswa enqubweni yemidiya esindayo. Bacindezelwa kabusha, bahlolwe, futhi baqondiswa kumafulethi.

I-Flotation - Okokuqala, izinto ezingancibilikisi ne-brine ziyasuswa kulezi zinhlayiya ezincane ze-ore kwinqubo ebizwa ngokuthi yi-desliming. Okulandelayo, i-ore inezinhlaka zamakhemikhali ezihlanganisa izinhlayiya ze-potash. Ngemuva kwalokho ihlanganiswa ne-brine. Lokhu kushunqiselwa kuphonswe emathangini e-flotation futhi umoya ufakwa engxenyeni. Izinhlayiya ezihlanganisiwe ze-potash zinamathela kumabhamuza womoya futhi zikhuphukele phezulu ekukhiqizeni amabanga Asezingeni Nakhe. I-potash isuswe isikhutha, isuswe izikhumba futhi yomile. Usawoti ongathinteki uhlala, ushona phansi.

I-Crystallization - Amanani, noma uthuli lwe-potash, ayatholakala kubuthakathaka bezinto zothuli nasenqubekweni yenqubo ye-scavenger flotation. Inhlawulo zihlakazwa ku-brine evuthayo futhi ziphinde zikhuliswe ngokupholisa ngezigaba ezintathu, kukhiqizwe amakristalu amakhudlwana, amsulwa we-potash (i-White Muriate). Lezi zinhlayiya zakhiwe ngumbala futhi zomile. I-White Muriate ingahle icwengeke i-99.9 iphesenti elicwengekile le-KCL ngokuvuselela kabusha. I-RefC KCl iphezulu ebumsulwa futhi isetshenziswa embonini yamakhemikhali.

Kuyahlanganiswa - I-Graphular grade potash yenziwe ukwenziwa kwengcindezelo ephezulu yamasayizi omile namaSpecial Standard asetshenziwe abe ngamaphakethi e-potash aqhekezwe futhi amakwe usayizi.

Isinyathelo Esisodwa - Amabanga amaningi athola ukwelashwa okukhethekile ukuze azivikele ngenkathi kuhanjiswa. Uma umkhiqizo womile kakhulu, uzothambekela othulini. Uma imanzi kakhulu, izothambekele ekhekheni. Ukuvimbela uthuli noma i-caking, umkhiqizo ufafazwa ngengxube yamafutha kanye ne-amine ngaphambi kokulayisha. I-White Muriate iphathwa kuphela nge-amine; I-KCl ekhanyisiwe ayidingi ukwelashwa.
