Umatshini wokucoca ipleyiti ngokuzenzekelayo unceda amashishini okumba ubhedu aseChile ukusombulula ingxaki yokuphelelwa ngamanzi emzimbeni

Imvelaphi yomthengi
Ishishini eliphakathi lemigodi yobhedu eliseChile linamandla okucubungula iitoni ezingama-3,000 ze-ore eluhlaza ngosuku. Kangangexesha elide, ukufuma okuphezulu kwe-slurry yayo ye-tailings kukhokelele kwiindleko eziphezulu zokuthutha kunye noxinzelelo olukhulu kumandla okugcina i-tailings.
Ukujongana nemingeni
Izixhobo zokuqala zokucoca zalo mthengi yayiziimodeli zohlobo lwe-lever ezenziwe ngesandla, ezazinokusebenza okuphantsi kokucubungula kwaye umxholo wokufuma kwekhekhe lesihluzo wawungaphezulu kwe-28%, ukungaphumeleli ukuhlangabezana neemfuno zokukhupha okusingqongileyo kunye nokuphinda kusetyenziswe amanzi. Kwangaxeshanye, imisebenzi eyenziwa rhoqo ngesandla nayo izisa iingozi zokhuseleko.
Isisombululo

Iinjineli zethu zilungiselele iiseti ezimbini zeIi-870 ngokuzenzekelayo ezisebenzisa iipleyiti zokufaka iibhokisi zohlobo lwebhokisikubathengi. Iyunithi nganye inendawo yokucoca engama-200 square metres. Lonke umatshini ulawulwa ngokuzenzekelayo yi-PLC kwaye iipleyiti zesihluzo kunye nemibhobho ziphuculwe zaba zizinto ezimelana nokugqwala ngokuhambelana neempawu ze-asidi ebuthathaka ze-copper ore slurry.
Iziphumo zokusebenza
Emva kokufakwa nokuqaliswa kwezixhobo, zaqhubeka nokusebenza kangangeenyanga ezi-6. Idatha ibonise ukuba umxholo wokufuma wekhekhe lesihluzo wahlala uzinzile kwi-16% ukuya kwi-18%, nto leyo eyayingaphantsi ngeepesenti ezili-10 kunezo zezixhobo zokuqala. Iindleko zokuthutha ngetoni nganye yeentsalela zenkunkuma zancitshiswa malunga ne-22%. Kwangaxeshanye, amanzi acocekileyo afunyenweyo aphinda asetyenziswa ngokuthe ngqo kwinkqubo yokuphucula, kunye nomthamo wokubuyisela wemihla ngemihla omalunga neetoni ezingama-800. Inkqubo yokuphakamisa iipleyiti ngokuzenzekelayo yacinezela ixesha lokukhupha umjikelo omnye ukusuka kwimizuzu engama-45 ukuya kwimizuzu eli-18. Inani labasebenzi ngeshifti nganye lancitshiswa ukusuka kwi-4 ukuya kwi-1.
Ingxelo yabathengi Umphathi wemveliso wefektri uthe izixhobo ezintsha ziphucule kakhulu ukusebenza kakuhle kokulahla iintsalela, nto leyo ebangele ukuba iikeyiki zokucoca ezomileyo kunye nokugcinwa okukhuselekileyo. Umsebenzi we-PLC wokwehlisa iipleyiti ngokuzenzekelayo wenza ukuba ukusebenza kuzinze nokuba kusebusuku. Bacebe uku-odola ezinye iiyunithi ezintathu zemodeli efanayo kwenye indawo yemigodi.
