Ukusukela ngeminyaka yoo-1990s, amazwe angaphandle aqalise ukufunda itekhnoloji ekrelekrele yokuxhamla kwaye enze inkqubela phambili yethiyori, efana ne-GunsonSortex yase-UK kunye ne-Outo-kumpu eFinland. kunye ne-RTZOreSorters, njl.njl., baye baphuhlisa kwaye bavelisa iintlobo ezingaphezu kweshumi ze-photoelectric sorters, i-radioactive sorters, njl., kwaye zisetyenziswe ngempumelelo kwintsimi yokuhlenga isinyithi esingenawo i-ferrous kunye neentsimbi ezixabisekileyo, kodwa ngenxa yexabiso eliphezulu, ukuchaneka kokuhlela okuphantsi, Umthamo wokulungisa umncinci, kwaye ulinganiselwe kunyuso kunye nesicelo.
Xa kuthelekiswa namazwe angaphandle, uphando lwetekhnoloji enxulumeneyo kwilizwe lam luqale emva kwexesha, kwaye indawo yophando imxinwa kakhulu. Malunga nowama-2000, abanye oomatshini bokuhlela bavela kwimarike yasekhaya, ngakumbi ukuhlenga imibala, ukuhlelwa kwe-infrared, ukuhlela umbane, njl. ubukhulu becala isetyenziselwa ukuhlela ukutya okuziinkozo, ukutya, iti, iyeza, iikhemikhali izinto ezikrwada, iphepha, iglasi, iNkunkuma yokuhlela kunye namanye amashishini, kodwa kwiintsimbi ezixabisekileyo nezinqabileyo njengegolide, umhlaba onqabileyo, ubhedu, itungsten, amalahle, intsimbi enemagnethi engenamandla, njl. ayikwazi ukukhethwa kwangaphambili kwaye ilahlwe kwangaphambili, ngakumbi kwizinto ezomileyo ezikrelekrele ezikhethiweyo zokuphosa umsila azinanto.
Okwangoku, imigodi yasekhaya ayinazo izixhobo ezisebenzayo ezikhethekileyo zokulahla kwangaphambili i-refractory ebuthathaka yemagnethi ekrwada, intsimbi ekrwada engeyontsimbi, njl.njl., ikakhulu ixhomekeke kwindlela yoqobo yokuhlela ngesandla kunye nendlela yokwahlula imagnethi, kunye nobungakanani besuntswana lokuhlela ngokubanzi. phakathi kwe-20 kunye ne-150 mm. Amandla aphezulu kunye neendleko eziphezulu. Kwiiminerali ezinomahluko omncinci kwimbonakalo yombala, ukubengezela, ukumila, kunye nokuxinana kwentsimbi ekrwada kunye nenkunkuma yamatye, ukusebenza kakuhle kokuhlela kuphantsi, impazamo inkulu, kwaye ezinye azikwazi ukwahlulwa. Kwimagnetite, indlela yokwahlula imagnethi ingasetyenziselwa ukuphosa imisila, kodwa kwiintsimbi ezineepropathi zemagneti ezibuthathaka, iintsimbi zentsimbi ezingeyontsimbi, njl.njl., impazamo yokwahlula inkulu, ukusebenza kakuhle kokwahlula kuphantsi, kwaye kukho inkcitho enkulu yezixhobo. .
Umatshini wokuhlela okrelekrele ulungele ukulungiswa kwentsimbi ekrwada ngesantya esiphezulu sokuxutywa kwentsimbi ekrwada kunye nesiphumo esihle sokwahlula phakathi kwelitye elijikelezileyo kunye nentsimbi ekrwada eluncedo emva kokutyunyuzwa.
01
Ukwehliswa komgangatho osikiweyo wemigodi kufana nokwandisa oovimba bemizi-mveliso yentsimbi ekrwada;
02
Ukunciphisa iindleko zokusila kunye nokuxhamla okulandelayo;
03
Umthamo wokucutshungulwa kwenkqubo unokuphuculwa phantsi komqathango wokuba izixhobo zokuqala zokusila zihlala zingatshintshi;
04
Ukuphucula ibakala elikhethiweyo kuluncedo ekuzinziseni nasekuphuculeni umgangatho wezigxinano kunye nokunciphisa iindleko zokunyibilikisa;
05
Ukunciphisa i-stock of fine-grained tailings, ukunciphisa iindleko zemveliso kunye nokugcinwa kwe-tailing pods, kunye nokuphucula into yokhuseleko ejikeleze indawo yokugcina amanzi.
Thatha imigodi yegolide njengomzekelo: okwangoku, ubutyebi begolide belizwe lam obungqiniweyo buziitoni eziyi-15,000-20,000, bukwindawo yesixhenxe kwihlabathi, kunye nemveliso yegolide yonyaka engaphezulu kweetoni ezingama-360, oovimba begolide bamatye abalelwa kwi-60%, kunye nomndilili. idiphozithi ibakala malunga 5%. Malunga ne-g/t, oovimba begolide bamatye bamalunga neetoni ezibhiliyoni ezi-3. Ibe ngoyena mvelisi mkhulu wegolide ehlabathini. Nangona kunjalo, inkqubo yokuzuza igolide kwilizwe lam isamkela inkqubo yesiqhelo yokudibanisa-concentrate cyanidation. Akukho ndlela isebenzayo yokujula imisila phambi kokuyityumza nokusila. Umthwalo womsebenzi wokutyumza, ukugaya kunye ne-flotation mkhulu, kwaye iindleko zokuxhamla zihlala ziphezulu. Izinga lelahleko yemigodi ingaphezulu kwe-5%, izinga lokubuyisela ukuxhamla kunye nokunyibilika malunga ne-90%, ixabiso le-beneficiation liphezulu, izinga lokubuyisela ubutyebi liphantsi, kwaye ukhuseleko lokusingqongileyo lusezantsi.
Emva kokulahla kwangaphambili ngokuhlelwa kwenzwa ekrelekrele, ilitye elikhethiweyo lenkunkuma lingaphendula i-50-80% yentsimbi ekrwada ekhethiweyo, ityebise ibakala elikhethiweyo legolide ngamaxesha angama-3-5, kunye nokunciphisa inani labasebenzi kwisityalo sokunxiba nge-15. -20% , 25-30% ukwanda kwenkunkuma elahliweyo kunye ne-10-15% kwimveliso yesinyithi.
Iindleko zokutyumza kunye nokugaya zingasindiswa ngaphezu kwe-50%, umthamo olandelayo wekhemikhali we-flotation ungancitshiswa ngaphezu kwe-50%, ukusebenza kakuhle kwemveliso kuphuculwe kakhulu, ixabiso lokuphinda lisetyenziswe inkunkuma yamatye iphuculwe, umonakalo wokusingqongileyo uyancitshiswa. , kwaye inzuzo yezoqoqosho iphuculwe kakhulu.
Uluhlu lwesayizi ye-particle ye-sensor sensor ehlakaniphile inokufikelela malunga ne-1mm ukuya kwi-300mm, kwaye inzwa inokuchonga ukuya kuma-40,000 amaqhekeza e-ore ngomzuzwana. Kuthatha kuphela i-ms ezimbalwa kwiqhekeza ngalinye lentsimbi ekrwada ekubhaqweni kwesixhobo soluvo esifumanayo ukuya kumyalelo wokuhlela ofunyenwe yi-actuator. Kuthatha kuphela ms ezimbalwa kwimodyuli yokutofa ukugqiba uphumezo olunye. Umthamo ophezulu wokucubungula umatshini omnye unokufikelela kwi-400 t / h, kwaye amandla okusebenza kwesinye isixhobo angafikelela kwi-3 yezigidi zeetoni ngonyaka, elilingana nesikali somgodi ophakathi kunye omkhulu.
Isixhobo sokuhlela isivamvo esikrelekrele sinokutshintsha ngokulula isoftware kunye nokuseta ngaphambili imibundu yokuhlela kwi-intanethi, kwaye iphendule ukuguquguquka komgangatho kunye nobungakanani bentsimbi ekrwada ekrwada ngexesha, engenako ukufezekiswa kwizixhobo zokuhlela zemveli.Njengoko intsimbi ekrwada ifikelela kwinqanaba elithile lokuqhekeka. kwinqanaba lokutyumza, nokuba kuphela iqondo lokuqhawula ilitye elijikelezileyo okanye i-ganggue, okanye i-concentrate yokugqibela iveliswa ngokuthe ngqo, isetyenziswa kakhulu kwiintsimbi ezahlukeneyo zetsimbi (ezingeyo-magnetic okanye zibuthathaka zintsimbi zentsimbi, ubhedu, ukukhokela, Ukukhethwa kwangaphambili kunye nokulahlwa kwenkunkuma ye-zinc, i-nickel, i-tungsten, i-molybdenum, i-tin, umhlaba onqabileyo, igolide, njl.), amalahle kunye neeminerali ezingezizo ezentsimbi ezifana ne-talc, i-fluorite, i-calcium carbonate, i-dolomite, i-calcite, i-apatite, njl. isixa soxinaniso olurhabaxa olungena kwinkqubo elandelayo luncitshiswe kakhulu, kwaye ibakala liphuculwe, elinokuthi linciphise kakhulu iindleko zokusila okulandelayo kunye ne-beneficiation.I-sentelligent sensor beneficiation ayihambelani nokuhlenga-hlengisa ngesandla, ukwahlula ngombane, kunye nokwahlulwa kombane ngokwemigaqo yokuchongwa. ukuchaneka, isantya sokuphendula, ukusebenza kakuhle kokuhlela, kunye nomthamo wokulungisa. Ukuhlela ngoluvo olukrelekrele lubonakaliso olubanzi lwetekhnoloji yale mihla yokuva kunye nobuchwepheshe bedijithali, kwaye iye yaba lelona khokelo lophuhliso lokukhethwa kwangaphambili kwezimbiwa.
Imithombo yamaminerali yaseTshayina ubukhulu becala i-ores ebhityileyo, kwaye umthamo wokugcina mkhulu. Indlela yokulahla inkunkuma kwangaphambili, ukuphucula ukusebenza kakuhle kokusila kunye nokuzuza uncedo, kunye nokunciphisa iindleko zokuxhamla, kunye nokusabela ngenkuthalo kwiimfuno jikelele zelizwe "zokwakhiwa kwemigodi ehlakaniphile kunye nemigodi eluhlaza", iya kuba yinto engenakuthintelwa uphuhliso loshishino lwemigodi yelizwe lam. Ke ngoko, uphuhliso lwezixhobo ezikrelekrele zokuhlela ezifanelekileyo ezifanelekileyo kwiiminerali zasekhaya sele lusondele, kwaye ithemba lemarike liya kuba libanzi kakhulu.
