Ukususela ngeminyaka yoo-1990, amazwe angaphandle aqalise ukufunda itekhnoloji yokuphucula izinto ngobuchule kwaye enze iinguqu ezithile zethiyori, ezifana neGunsonSortex e-UK kunye ne-Outo-kumpu eFinland. kunye neRTZOreSorters, njl., ziye zaphuhlisa zaza zavelisa iintlobo ezingaphezu kweshumi zee-photoelectric sorters zoshishino, ii-radioactive sorters, njl., kwaye zisetyenziswe ngempumelelo kwicandelo lokuhlela iintsimbi ezingezizo iintsimbi kunye neentsimbi ezixabisekileyo, kodwa ngenxa yexabiso eliphezulu, ukuchaneka kokuhlela okuphantsi, amandla okucubungula mancinci, kwaye anqongophele ekukhuthazeni nasekusetyenzisweni.
Xa kuthelekiswa namazwe angaphandle, uphando lwetekhnoloji oluhambelanayo kwilizwe lam luqale kade, kwaye icandelo lophando lincinci kakhulu. Malunga nowama-2000, ezinye iimatshini zokuhlela nazo zavela kwimarike yasekhaya, ikakhulu ukuhlela imibala, ukuhlela i-infrared, ukuhlela ngombane, njl.njl., ezisetyenziselwa ukuhlela iinkozo, ukutya, iti, amayeza, izinto ezikrwada zeekhemikhali, iphepha, iglasi, ukuhlela inkunkuma kunye namanye amashishini, kodwa kwiintsimbi ezixabisekileyo nezinqabileyo ezifana negolide, umhlaba onqabileyo, ubhedu, i-tungsten, amalahle, i-magnetic iron ore ebuthathaka, njl.njl. azinakukhethwa kwangaphambili kwaye zilahlwe kwangaphambili, ingakumbi kwizixhobo zokukhangela ezomileyo ezikrelekrele, izixhobo zokuphosa umsila azinanto.
Okwangoku, imigodi yasekhaya ayinazo izixhobo ezikhethekileyo ezisebenzayo zokulahla i-ore ze-magnetic ezibuthathaka ezingabonakaliyo, i-ore zesinyithi ezingenayo i-ferrous, njl.njl., ikakhulu zixhomekeke kwindlela yokuqala yokwahlula ngesandla kunye nendlela yokwahlula i-magnetic, kwaye ubungakanani be-particle yokuhlela ngokubanzi buphakathi kwama-20 kunye nama-150 mm. Amandla aphezulu kunye neendleko eziphezulu. Kwiiminerali ezinomahluko omncinci kwimbonakalo yombala, ukukhanya, imilo, kunye noxinano lwe-ore kunye nelitye elilahlekileyo, ukusebenza kakuhle kokuhlela kuphantsi, impazamo inkulu, kwaye ezinye azinakwahlulwa. Kwi-magnetite, indlela yokwahlula i-magnetic ingasetyenziselwa ukuphosa imisila, kodwa kwii-ore ezineempawu ze-magnetic ezibuthathaka, i-ore zesinyithi ezingenayo i-ferrous, njl.njl., impazamo yokwahlula inkulu, ukusebenza kakuhle kokuhlula kuphantsi, kwaye kukho inkcitho enkulu yezixhobo.
Umatshini wokuhlunga we-sensor okrelekrele ufanelekile ekunyangweni kwe-ore kwangaphambili ngesantya esiphezulu sokunyibilika kwe-ore eluhlaza kunye nesiphumo esihle sokwahlula phakathi kwelitye elijikelezileyo kunye ne-ore eluncedo emva kokutyunyuzwa.
01
Ukunciphisa umgangatho wokusika kwemigodi kufana nokwandisa iindawo zokugcina iore kwimizi-mveliso;
02
Ukunciphisa iindleko zokugaya nokuphucula emva koko;
03
Umthamo wokucubungula kwenkqubo unokuphuculwa phantsi kwemeko yokuba izixhobo zokugaya zokuqala azitshintshi;
04
Ukuphucula umgangatho okhethiweyo kunceda ekuzinziseni nasekuphuculeni umgangatho wezinto ezixutyiweyo kunye nokunciphisa iindleko zokunyibilikisa;
05
Nciphisa isitokhwe seentsalela zezityalo ezicolekileyo, nciphisa iindleko zemveliso kunye nokugcinwa kwamachibi eentsalela zezityalo, kwaye uphucule ukhuseleko olujikeleze indawo yedama.
Umzekelo, masenze umzekelo ngemigodi yegolide: okwangoku, imithombo yegolide eqinisekisiweyo yelizwe lam iphakathi kweetoni ezili-15,000-20,000, ikwindawo yesixhenxe kwihlabathi liphela, apho imveliso yegolide yonyaka ingaphezulu kweetoni ezingama-360, iindawo zokugcina igolide yelitye zimalunga ne-60%, kunye nomgangatho ophakathi wediphozithi ye-ore emalunga ne-5%. Malunga ne-g/t, iindawo zokugcina igolide yelitye zimalunga neetoni ezi-3 zeebhiliyoni. Ibe ngumvelisi omkhulu wegolide kwihlabathi. Nangona kunjalo, inkqubo yokuzuza igolide kwilizwe lam isasebenzisa inkqubo yendabuko yokukhulisa i-flotation-concentrate cyanidation. Akukho ndlela isebenzayo yokuphosa imisila ngaphambi kokutyumza nokusila. Umsebenzi wokutyumza, ukugaya kunye nokusila mkhulu, kwaye iindleko zokuzuza zihlala ziphezulu. Izinga lokulahleka kwemigodi lingaphezulu kwe-5%, izinga lokubuyisela ukuhluza kunye nokunyibilikisa limalunga ne-90%, iindleko zokuzuza ziphezulu, izinga lokubuyisela izixhobo liphantsi, kwaye ukhuseleko lokusingqongileyo alulunganga.
Emva kokulahlwa kwangaphambili ngokucwangcisa i-sensor ekrelekrele, ilitye lenkunkuma elikhethiweyo linokubalelwa kwi-50-80% ye-ore eluhlaza ekhethiweyo, liphucula umgangatho wegolide okhethiweyo ngokuphindwe ka-3-5, kwaye linciphise inani labasebenzi kwisityalo sokugquma nge-15-20%, ukwanda kwe-25-30% kwilitye lenkunkuma elilahliweyo kunye ne-10-15% kwimveliso yesinyithi.
Iindleko zokutyumza nokusila zinokongiwa ngaphezulu kwe-50%, umthamo wekhemikhali olandela oko unokuncitshiswa ngaphezulu kwe-50%, ukusebenza kakuhle kwemveliso kuphuculwe kakhulu, ixabiso lokusetyenziswa kwakhona kwelitye lenkunkuma liphuculwe, umonakalo ongqongileyo uyancipha, kwaye inzuzo yezoqoqosho iphuculwe kakhulu.
Uluhlu lobukhulu beesuntswana zokuhlelwa kweenzwa ezikrelekrele lunokufikelela malunga ne-1mm ukuya kwi-300mm, kwaye isensor inokuchonga iziqwenga ze-ore ezifikelela kuma-40,000 ngomzuzwana. Ithatha i-ms ezimbalwa kuphela kwisiqwenga ngasinye se-ore ukusuka ekufumaneni isensor efumanayo ukuya kumyalelo wokuhlela ofunyenwe yi-actuator. Ithatha i-ms ezimbalwa kuphela kwimodyuli yokujova ukuze igqibezele ukusebenza kube kanye. Ubungakanani obukhulu bokucubungula bomatshini omnye bunokufikelela kwi-400 t/h, kwaye amandla okucubungula esixhobo esinye anokufikelela kwi-3 yezigidi zeetoni ngonyaka, okulingana nobukhulu bomgodi ophakathi nomkhulu.
Izixhobo zokuhlunga iisensor ezikrelekrele zinokutshintsha ngokulula isoftware kunye nemida yokucwangcisa esele imiselwe kwi-intanethi, kwaye ziphendule kutshintsho kumgangatho kunye nobungakanani be-ore eluhlaza ngexesha, okungenakufezekiswa kwizixhobo zokuhlunga zemveli. Logama nje i-ore eluhlaza ifikelela kwinqanaba elithile lokuhlukana kwinqanaba lokutyumza, nokuba kuphela yinqanaba lokuhlukana kwelitye elijikelezileyo okanye i-gangue, okanye i-concentrate yokugqibela iveliswa ngokuthe ngqo, isetyenziswa kakhulu kwii-ore zesinyithi ezahlukeneyo (i-ore yesinyithi engengomagnetic okanye ebuthathaka, ubhedu, i-lead, ukulahla inkunkuma ye-zinc, i-nickel, i-tungsten, i-molybdenum, i-tin, i-rare earth, igolide, njl.njl.), iiminerali zamalahle kunye nezingezizo zesinyithi ezifana ne-talc, i-fluorite, i-calcium carbonate, i-dolomite, i-calcite, i-apatite, njl.njl. Ubungakanani be-concentrate ecoarse engena kwinkqubo elandelayo incitshiswa kakhulu, kwaye umgangatho uyaphucuka, nto leyo enokunciphisa kakhulu iindleko zokugaya kunye nokuphucula okulandelayo. I-concentrate yeesensor ekrelekrele ayinakuthelekiswa nokuhlelwa kwendabuko ngesandla, ukwahlula i-magnetic, kunye nokwahlula i-photoelectric ngokubhekiselele ekuchanekeni kokuchonga, isantya sokuphendula, ukusebenza kakuhle kokuhlela, kunye namandla okucubungula. Ukuhlela okukrelekrele kokuva luphawu olupheleleyo lwetekhnoloji yokuva yanamhlanje kunye netekhnoloji yedijithali, kwaye kube yindlela ephambili yophuhliso lokukhethwa kwangaphambili kwezimbiwa.
Izixhobo zezimbiwa zaseTshayina ikakhulu zii-ore ezingenamafutha amaninzi, kwaye amandla okugcina makhulu. Indlela yokulahla inkunkuma kwangaphambili, ukuphucula ukusebenza kakuhle kokusila nokuphucula okulandelayo, kunye nokunciphisa iindleko zokuhluza, kunye nokuphendula ngokukhutheleyo kwiimfuno eziqhelekileyo zelizwe "zokwakha iimayini ezikrelekrele kunye nemigodi eluhlaza", ngaba iye yaba ngumkhwa ongenakuphepheka kuphuhliso lweshishini lezemigodi yelizwe lam. Ke ngoko, uphuhliso lwezixhobo zokuhlunga ezikrelekrele ezifanelekileyo kwiimayini zasekhaya lusondele, kwaye amathuba emarike aya kuba banzi kakhulu.
