Emkhakheni wokucubungula imayini, ukuvuselelwa kwemaminerali amancane kakhulu sekubaluleke kakhulu ngenxa yokusetshenziswa kwawo okuningi kanye nenani elikhulu emikhakheni ehlukene. Imaminerali amancane kakhulu, ikakhulukazi lezo ezinzima, ziveza izinselelo ezihlukile ekukhipheni nasekuthuthukiseni, kuvame ukuholela ekulahlekelweni okukhulu ngesikhathi sokucubungula okujwayelekile. I-Alicoco Mineral Technology Co., Limited, ehamba phambili ekwakhiweni kwezinto ezintsha zokucubungula imayini, ithuthukise izixazululo zokuvuselela eziphambili ezibhekana nalezi zinselelo ngempumelelo. Le ndatshana ihlola ubunjalo bemaminerali amancane kakhulu, izithiyo ezitholakala ekubuyiseni kwabo, kanye nezinqubo zomzimba ezisha ze-Alicoco ezikhulisa umkhiqizo wemayini ngenkathi kusekelwa izinqubo zokumba eziqhubekayo.

Ultrafine minerals zisho ama-particles anobukhulu obuvamile ngaphansi kuka-50 microns, abonisa izakhiwo zomzimba nezokwakheka ezihlukile uma kuqhathaniswa nezinye ezinkulu. Lezi zinsimbi zikhona kakhulu emigodini ye-refractory, eyaziwa ngokumelana nezindlela zokukhipha ezijwayelekile. Isikali se-ultrafine salawa ma-particles sivame ukuholela ezinkingeni ekwehlukaniseni nasekutholeni usebenzisa izindlela zokuthuthukisa ezijwayelekile, ezifana ne-flotation noma ukuhlukaniswa kwe-gravity. Izici ezifana nendawo enkulu yokuphila, ukuthanda ukuhlanganisa, kanye nezixhumanisi eziyinkimbinkimbi ze-mineral zidinga izinqubo ezikhethekile ukuze kutholakale kahle. Imikhakha ehlukene kusukela ku-metallurgy kuya ku-ceramics nase-electronics ithembele kakhulu kumgangatho nokuhlanzeka kwalezi zinsimbi ze-ultrafine.

Ngenxa yobukhulu bayo obuncane, imayini ezincane kakhulu zihluleka ukuhamba ngesikhathi sokucubungula etafuleni lokush shake noma emgqeni ophakanyisiwe. Lezi zikhala azinciphisi kuphela inani lezomnotho lokusebenza kwemayini kodwa futhi zikhathaza imvelo ngokwandisa ivolumu yezinto eziphukile. Ngakho-ke, ukuvuselelwa kahle kwezigaba zemayini ezincane kakhulu kuyisidingo sobuchwepheshe kanye nemvelo.

Ukubuyiselwa kwemaminerali e-ultrafine engakwazi ukujabulisa kunzima kakhulu ngenxa yobukhulu bayo obuncane kanye nobunzima bayo bemaminerali. Amathuluzi ajwayelekile okwehlukanisa ngegravity, njengezinkundla ezishukumisayo, avame ukuba nobunzima ekubuyiseleni lezi zinsalela ezincane kahle. Lezi zinsalela ezincane zihlala zihlolwa ngempela nezinsalela – i-slurry yedlulelo ekhishwa ngemva kokuhlukaniswa kwemaminerali afunwayo. Lokhu kuholela ekulahlekelweni okungamukeleki kwemaminerali ayigugu kanye nokwehla kokusebenza kwenqubo jikelele.

Ngaphezu kwalokho, izinhlelo ze-chute ezithambile, ezivame ukusetshenziswa ezitsheni zokucubungula imayini, zingase zingakwazi ukuhlukanisa kahle ama-particulate amaminerali aphansi kakhulu ngenxa yezithiyo zawo zomzimba. Ukuhlanganiswa nokuhlangana kwe-particulate aphansi kakhulu kwenza kube nzima ukuwathola, kwesinye isikhathi kuholela ekubambeni noma ekuhlukaniseni okungasebenzi kahle. Ngaphezu kwalokho, ama-minerali angavumeli ukujula ngokuvamile adinga ukwelashwa kwangaphambi kokuthi noma izinqubo zomzimba ezikhethekile ukuze kukhululwe kahle izingxenye ezibalulekile. Njengoba kunjalo, izindlela zokubuyisa ezijwayelekile zivame ukuwa phansi ekwandiseni izinzuzo zokubuyisa, kuholela ekudingekeni kwezixazululo zobuchwepheshe obusha.

Ukubhekana nesidingo esibalulekile sokuthuthukiswa kokubuyiselwa kwemaminerali amancane kakhulu, i-Alicoco Mineral Technology Co., Limited ithuthukise izinqubo zokubuyisela eziphambili ezihambisana nezici ezihlukile zemaminerali amancane kakhulu angavumi. Imiklamo yabo ye-spiral chute epatentiwe nezinye izinsiza zokuhlukanisa ngokwejwayelekile zenzelwe ukuthola ama-particles amancane kakhulu avamise ukuphuthelwa emathunjini avela kumathebula ajwayelekile okushaya kanye nezinhlelo ze-chute ezithambile.

Ubuchwepheshe bokubuyisela obuphuma ku-Alicoco bugcizelela ukuhlukaniswa komzimba okuthambile kodwa okusebenza kahle, kunciphisa ukuphuka kwezakhi ezincane ngenkathi kuthuthukiswa amazinga okubuyiselwa. Ngokusebenzisa ukuhamba kwemifantu okulawulwayo nokuthuthukisiwe kokuhamba kwezinto ngaphakathi kweziteshi zabo ezijikelezayo, imishini ye-Alicoco iqinisekisa ukuhlukaniswa okungcono nokuhlukaniswa kwezinsimbi ezincane kakhulu. Le nqubo yomzimba ikhipha isidingo sokusebenzisa izinto zokwakha ezikhemikhali, ihambisana nezindlela zokumba ezihlonipha imvelo.

Ngaphezu kwalokho, indlela ye-Alicoco ihlanganisa izixazululo ezihlukahlukene nezokwenza ngendlela oyifisayo ezingahlanganiswa ezitsheni zokucubungula imayini ezikhona ngaphandle kokuphazamiseka okukhulu. Ubuchwepheshe babo abuthuthukisi kuphela ukusebenza kahle kokubuyiselwa kodwa futhi buyehlisa izindleko zokusebenza ngokunciphisa ukulahleka kwemayini nokwehlisa izinga le-tailing. Ukuzibophezela kwenkampani ekwakhiweni kwezinto ezintsha nasekugcineni kuyabhalwa kahle, okwenza kube umngane othembekile ekubuyiseleni imayini engaphendukiyo.

Ukukhulisa ukuvuselelwa kwemaminerali e-ultrafine e-refractory kunikeza izinzuzo ezinkulu zemvelo nezomnotho. Ngemvelo, ukunciphisa ukulahleka kwemaminerali ezindaweni zokugcina kwehlisa ivolumu ye-slurry yodoti okumele ukuphathwe yimisebenzi yokumba, ngaleyo ndlela kunciphisa ubungozi bokungcoliswa komhlaba namanzi. Ukuvuselelwa kahle kunciphisa isidingo sokumba okwengeziwe, kugcine izinsiza zemvelo futhi kwehlise umthelela wemvelo wemisebenzi yokukhipha imaminerali.

Ngokwezezimali, izinga elithuthukisiwe lokubuyiselwa kwezimali lihunyushwa ngqo kube ukwanda kokwenzayo kwezimayini. Ngokubuyisela izinsiza ezibalulekile ezivela kumathala, izinkampani zingathuthukisa ukusetshenziswa kwezinsiza futhi zinciphise izindleko ezihambisana nokuthengwa kwezinto zokwakha. Izixazululo zokubuyiselwa kwezimali ezincane ze-Alicoco zenza amaklayenti akwazi ukubuyisela imikhiqizo eminingi kusuka kumaminerali afanayo, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwekhava yonke. Ngaphezu kwalokho, ukuncipha kokusetshenziswa kwemichiza nokusetshenziswa kwamandla ngezindlela zokubuyiselwa zomzimba kuthuthukisa ukonga izindleko futhi kusekela imigomo yokusimama kwezinkampani.

I-Alicoco's innovative recovery technologies isetshenziswe ngempumelelo emaphrojeni amaningi emhlabeni jikelele, ikhombisa ukusebenza kwayo ezimeni zangempela. Kwesinye isimo, ukuhweba ngegolide kuhlanganise uhlelo lwe-Alicoco olune-patent lwe-spiral chute emgqeni wabo wokucubungula futhi babona ukwanda kokubuyiselwa kwezigqoko zegolide ezincane ngaphezu kuka-15%, kunciphisa kakhulu ukulahleka kwe-tailing. Le ntuthuko ayithuthukisanga kuphela imbuyiselo yezezimali ye-mine kodwa futhi yathuthukisa izindlela zokuphatha udoti ezinzile.

Esinye isibonelo sibe yindawo yokucubungula i-hematite esebenzisa izixazululo zokubuyisela ze-Alicoco ukuze ibuyisele ama-particles e-hematite aphukile ngaphambilini avela kumathuluzi e-felted chute. Umphumela waba ukwanda okukhulu kwekhwalithi ye-concentrate kanye nokukhiqiza jikelele, kuqinisekisa ukufaneleka kobuchwepheshe ezinhlelweni ezahlukene zezimbiwa. Ulwazi olunembile ngalezi zinhlelo lungatholakala ku-Alicoco’s Amacala ikhasi.

Ukubuyiselwa kwezinsimbi ezincane kakhulu eziphikisanayo kubalulekile ukuze kuthuthukiswe ukusebenza kahle kwezinsiza nokunciphisa umthelela kwemvelo. I-Alicoco Mineral Technology Co., Limited ihola umkhakha ngezindlela ezintsha zokubuyisela eziklanyelwe ukunqoba izinselelo zokuhlukaniswa kwezinsimbi ezincane kakhulu. Imishini yabo enamalungelo obunikazi nezixazululo ezenziwe ngokwezifiso zenza ukuthi imisebenzi yokumba ibuyisele izinsimbi ezibalulekile ezilahlekile emathunjini, ithuthukise inzuzo, futhi yamukele izindlela ezinzile kakhulu.

Kwibhizinisi efuna ukuthuthukisa imisebenzi yokucubungula imayini, i-Alicoco inikeza ubuchwepheshe obuphelele nezobuchwepheshe ezivele zafakazelwa. Ukuze ufunde kabanzi ngemicimbi yabo emisha nemisebenzi, vakashela ku-Mayelana Nathi ikhasi noma uhlole uhla lwabo olubanzi lwe Imikhiqizo. Ukuze uthole imibuzo nokubonisana, Xhumana ikhasi linikeza ukufinyelela okuqondile eqenjini labo lochwepheshe elilungele ukusiza.
