Izinsalela zemizila yezimbiwa yizinto ezishiyekile ngemuva kokuthi izimbiwa eziwusizo zikhiyiwe emadwaleni ngenkathi kwenziwa imisebenzi yezimbiwa. Ngokomlando, lezi zinsalela zazibhekwa njengodoti futhi zazivame ukulahlwa ngaphandle kokucatshangelwa okunye. Kodwa-ke, njengoba isidingo sezimbiwa ezibalulekile sikhula, umbono wezinsalela zemizila yezimbiwa uyashintsha ukuze ubone inani lazo elifihlekile. Izinsalela zivame ukuba namazinga amaningi ezimbiwa ezifana nensimbi, ithusi, igolide, nezinga eliphansi lezinto ezingekho ezazingenziwa ukuthi zitholakale ngobuchwepheshe obudala. Ukuqonda ukwakheka namandla ezinsalela zemizila yezimbiwa kubalulekile ekuthuthukiseni izindlela zokumba izimbiwa ezizinzile ezihambisana nezinqubomgomo zomnotho oyindilinga. Leli shintsho alusizi kuphela ekulondolozweni kwezinsiza kodwa futhi lwehlisa imithelela yezemvelo ehambisana nokulahlwa kukadoti wezimbiwa ojwayelekile.

Eminyakeni yamuva nje, izindlela ezisimeme ziye zaba yisisekelo embonini yokucubungula amaminerali. Ukugcizelela ukusetshenziswa kabusha nokutholwa kwamaminerali kusuka kumagobolondo (tailings) kusekela umnotho oyindilinga ngokunciphisa isidingo sokukhipha izinsiza ezintsha nokunciphisa ukubhidlika kwemvelo. Ukuhlanganiswa kobuchwepheshe obuthuthukisiwe bokuthola kuvumela umkhakha wezimayini ukuthi uthole amaminerali amahle kakhulu ayelahleka ngaphambili, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwezinsiza. I-Alicoco Mineral Technology Co., Limited isezingeni eliphezulu kule nkululeko, inikeza ubuchwepheshe obuthuthukisiwe be-spiral chute obuklanyelwe ukuthola amaminerali amahle futhi anzima ukutholakala ngempumelelo. Lesi sihloko sihluza isimo samanje, izinselelo, izinto ezintsha, namathuba esikhathi esizayo ekutholeni amaminerali emagobolondweni, sigcizelela inani lawo njengezinsiza ezisimeme.

Izibalo zakamuva ziveza ukuthi izigidi zamathani ezimbiwa eziyigugu zisavalelwe emadoti emhlabeni wonke. Ngokwesibonelo, amadoti e-iron ore kuphela amele umthombo omkhulu ongasebenziseki onobuningi obukhulu be-iron oxides nezinye izimbiwa. Njengoba isidingo somhlaba wonke sezimbiwa ezisetshenziswa kwezobuchwepheshe bamandla avuselelekayo njengezinsika zomoya, izimoto zikagesi, namaphaneli elanga zikhula kakhulu, ukuthola lezi zimbiwa emadoti kuyaba kubaluleke kakhulu. Izingcindezi zokuhlinzekwa kwezimbiwa ezibalulekile—njenge-cobalt, i-lithium, ne-rare earth elements—ziye zandisa isithakazelo ezinsizeni zesibili ezifana namadoti njengezindawo ezihlukile.

Ukutholwa kwezinsimbi emadoti akugcini nje ngokuhlanganisa isidingo sezinsimbi kodwa futhi kunciphisa umthelela omubi wezimayini emvelweni. Ngokucubungula kabusha amadoti, izinkampani zinganciphisa ukukhishwa kwazo kwe-carbon, kunciphise ukusetshenziswa kwamanzi, futhi kunciphise ukuphazamiseka komhlaba okuhlobene nemisebenzi emisha yezimayini. Indima yamadoti ezinsimbi ekulawuleni izinsiza ezisimeme ihambisana nemizamo yomhlaba wonke yokufinyelela ukukhishwa kwe-net-zero kanye nokukhuthaza ubuchwepheshe obuluhlaza. Ubuchwepheshe obusha be-spiral chute buka-Alicoco buveza izindlela zokuthola ezisebenzayo ezigxile ezintweni ezincane kakhulu zezinsimbi, kuthuthukisa isivuno sezinsimbi emadoti ayekade ethathwa njengemfucuza.

Ngaphandle kwesithembiso esikhulu samatshe amaminerali, izinselelo eziningana zivimbela ukwamukelwa okubanzi kwezindlela zokubuyisa. Emhlabeni wonke, izinto ezibalulekile zamaminerali zibhekana nokuphazamiseka ngenxa yezinkinga zezombusazwe, amandla omsebenzi wokumba ancishisiwe, kanye nemithetho yezemvelo. Ukubuyisa amatshe amaminerali kudinga ubuchwepheshe obuthuthukisiwe obungakwazi ukukhipha amaminerali ngokomnotho akhona ngamanani aphansi noma ngamafomu ayinkimbinkimbi emaminerali. Izinhlelo zokubuyisa zakudala njengamathebula okuzamazama nezinhlelo zezitebhisi ezinezindwangu ngokuvamile ziyahluleka ukubamba amaminerali acashile, okuholela ekulahlekelweni okukhulu kwezinsiza.

Izixazululo zobuchwepheshe ezintsha zibalulekile ukunqoba lezi zinselelo. I-Alicoco Mineral Technology Co., Limited isungule izinhlelo zokudonsa ezine-patent eziklanyelwe ukuthola amaminerali amahle ngokusebenzisa izinqubo zomzimba ngempumelelo. Lezi zindlela zobuchwepheshe zibhekana nemikhawulo yezinhlelo ezindala, ezivumela ukutholwa kwamaminerali avame ukulahleka emadoti. Ngaphezu kwalokho, imithetho yezemvelo kanye nezikhalazo zomphakathi zidinga ukuthi amaphrojekthi okuthola amaminerali emadoti ahambisane namazinga aqinile ezemvelo nezokuphepha, okwenza ukwethulwa kwephrojekthi kube nzima nakakhulu. Noma kunjalo, izinzuzo zokutholwa okuphumelelayo—okuhlanganisa ukonga izinsiza, ukunciphisa umthelela kwezemvelo, kanye nenzuzo yezenotho—kugqugquzela ucwaningo nentuthuko eqhubekayo kule ndawo.

Iphrojekthi eziningana eziphumelelayo emhlabeni wonke zikhombisa ukusebenza kanye nezinzuzo zokuthola izinsimbi ezivela ezinsimbini eziyimpahla. Ngokwesibonelo, izinsimbi eziyimpahla zensimbi e-Australia naseNingizimu Afrika ziye zaphinda zacutshungulwa ukuze kutholwe okuqukethwe okwengeziwe kwensimbi kusetshenziswa izinto zokuhlanganisa ezithuthukisiwe kanye nezinqubo zokuhlanganisa. Lezi phrojekthi azigcinanga ngokwandisa ukusebenza kahle kwezinsiza kodwa futhi zadala amathuba ezomnotho ngokudala imisebenzi kanye nokunciphisa izindleko zokuphatha udoti.

I-Alicoco Mineral Technology Co., Limited ibe nendima ebalulekile ekuthuthukiseni ubuchwepheshe bokuthola izinsimbi ezisendlini. Izinhlelo zabo ze-spiral chute ezinelungelo lobunikazi zenzelwe ngokukhethekile ukuthola kahle amaminerali amahle kakhulu futhi anzima ukutholakala alahleka ngezindlela ezijwayelekile. Ubuchwepheshe be-Alicoco buasetshenziswa emaphrojekthini amaningi ukuthola amaminerali anenani njenge-hematite, i-tin, igolide, nezinye izakhi ezibalulekile ezisendlini. Izifundo zamacala ezinemininingwane ziyatholakala ku-Amacala ikhasi ligcizelela ubuchwepheshe benkampani nezinzuzo ezibonakalayo zezixazululo zayo. Lezi zinto ezintsha azithuthukisi kuphela amazinga okuthola amaminerali kodwa futhi zisekela izindlela zokumba ezisimeme ngokunciphisa umthelela emvelweni.

Izinsiza ezisetshenziswa emayeleni esikhathini esizayo zinikeza amathuba amahle okwandisa imisebenzi nokukhula kwemakethe. Njengoba izinkampani zezimayela kanye nohulumeni beqhubeka nokuphambili ukusimama nokusebenza kahle kwezinsiza, isidingo sobuchwepheshe bokucubungula kabusha izinsiza kulindeleke ukuthi sikhule. Ukwandisa ukutholwa kwezinsiza kungasiza ukubhekana nokushoda kwezinsiza ezibalulekile nokusekela ushintsho lwamandla avuselelekayo ngokuvikela ukuhlinzekwa okuzinzile kwezinsiza ezibalulekile. Izimakethe ezivelayo kanye nemithetho eguqukayo zikhuthaza kakhulu utshalomali ezixazululweni ezintsha zokutholwa kwezinsiza.

Izinhlangano ezifana ne-Alicoco Mineral Technology Co., Limited zihlezi kahle ukuhola lokhu kukhula ngobuchwepheshe bazo bokuthola obuthuthukisiwe nokuzibophezela ezixazululweni zokumba ezihambisana nemvelo. Amabhizinisi ahlola ukuthola imfucumfucu yamaminerali angazuza ngokubambisana nabahlinzeki bezobuchwepheshe abasungulwe ukusebenzisa izixazululo ezisebenzayo, ezikaliwe. Ngemininingwane eyengeziwe ngemikhiqizo namasevisi amasha e-Alicoco, vakashela i Mayelana Nathi ikhasi. Ngaphezu kwalokho, imininingwane enemininingwane ngemikhiqizo itholakala ku-Imikhiqizo ikhasi, libonisa ubuchwepheshe obubhekana nezinselelo zokuthola izimbiya ezicashile kakhulu.

Izinsalela zamaminerali ziyisipho esingasetshenziswanga kahle esingaba nomthelela omkhulu ezimayini ezisimeme kanye nemikhuba yomnotho oyindilinga. Isidingo esikhulayo samaminerali abalulekile esishukumiswa amandla avuselelekayo kanye nentuthuko yezobuchwepheshe sigcizelela ukubaluleka kokuthola amaminerali anenani ezinsizaleni. Ngenkathi kunezinkinga, izinto ezintsha ezifana nobuchwepheshe obunelungelo lobunikazi be-Alicoco obuhlanganisa izimbazo zokudonsa zibonisa ukuthi izinqubo zokuthola ngokomzimba zingavula amaminerali amahle kakhulu ayelokhu elahlekile ezinsizaleni.

Ukutshala imali ocwaningweni, ukuthuthukiswa kobuchwepheshe, nengqalasizinda yokuthola izinsimbi ezisendlini kubalulekile ukukhulisa ukusetshenziswa kwezinsiza nokunciphisa imithelela emvelweni. Izinkampani zezimayini, abenzi bezinqubomgomo, nabahlinzeki bezobuchwepheshe kufanele babambisane ukuze balethe lezi zixazululo ukuze kube nekusasa elisimeme kakhudlwana. Kubantu abanentshisekelo yokuhlola amathuba kanye nezinto ezintsha zobuchwepheshe kule ndawo, i-Alicoco Mineral Technology Co., Limited inikeza izixazululo ezisezingeni eliphezulu kanye nobuchwepheshe.

Ukufunda kabanzi noma ukuqala ukubambisana, sicela uvakashele i Xhumana Nathi ikhasi noma uhlole izibuyekezo zakamuva ze-Alicoco ku Izindaba ikhasi.
