Imvelaphi yokuqhutywa kweminemishini kunye nembali yeenkqubo zedosi

Ekupheleni kwenkulungwane ye-19, kwabakho utitshala wesikolo waseAmerican ogama linguKelly Abbasser. Umyeni wakhe wayeyilungisa lomatshini womgodi. Ngenye imini, umyeni wakhe wabuyisa i-chalcoprite. Wayefuna ukuba acoce ibhegi yeoyile aze ayisebenzise ngenye injongo. Ufumanise ukuba ngexesha lenkqubo yokucoca, amasuntswana amancinci eChalcopperi anokuhambisana neebhubhu zesepha kwaye adada emanzini, ngelixa umhlaba watshona kwibhakethi. Ekugqibeleni, le yafunyanwa ngengozi yayiyimvelaphi yetekhnoloji entsha yeFlotation kunye nokuSebenza kwezimbiwa.

Kudlula iminyaka engaphezu kwekhulu, kwaye itekhnoloji yokuqhutywa sele iphuculwe ngokuqhubekayo kwaye izicelo zayo ziye zaxhaphake ngakumbi. Ngokweenkcukacha-manani, iipesenti ezingama-90 ze-ores zentsimbi ezingengongabi sehlabathi ngoku ziqwalaselwa ngefloti. Ukongeza, iflotation isetyenziswa ngokubanzi. Isetyenziselwa ukulungisa iintsimbi ezinqabileyo, izinyithi ezixabisekileyo, izinyithi ezibi, ezingengaphantsi, amalahle kunye nezinye izinto ezingafunekiyo.

Kwinkqubo yeflethi yale mihla, isicelo kunye nokongezwa ngokuchanekileyo kwe-Recgeents zibaluleke kakhulu, kuba emva konyango ngeerejista, ukuze iiminerali zinamathele ngokukhethekileyo kwiiBuble, ngokuthile ukuze afezekise Injongo yokuqhubekiswa kwezimbiwa.

Imbali yoPhuculo lweNkqubo yoMbutho we-Ageral

Phambi kokuqulunqwa kwemijikelezo ye-Loogic, izityalo zokuqhekeza zokuqala ezisetyenzisiweyo ukongezwa kweekhemikhali zeekhemikhali. Ukuthembela kumava obuqu kubesebenzi bobuqu, ukuvulwa kwe-valical ivalve yayihlaziywa ngesandla ukuba ihlengahlengise ireyithi yokuhamba kweekhemikhali.

Ngo-1960s, njengoko ubuchwepheshe bemoto ovuthiweyo, injineli yaseAmerican Rinesving yamanzi i-Andruos isebenzise umgaqo-nkqubo wamanzi wokufumana umatshini wokufumana i-scoop. Ngokutshintsha ivolumu kunye nenombolo ye-SCOOPS kwiplate ye-scoop, inani lamayeza elongeziweyo litshintshiwe. ukuhamba.

Kodwa nje ukulawula ukuhamba kweekhemikhali zeflotation ngokujikeleza kude ngokwaneleyo. Emva kweminyaka yee-1970, i-fissitor-i-contraltorles edibeneyo yesekethe (isekethe elihlanganisiweyo) latshintshelwa kwishishini loomkhosi ukuya kusetyenziswa. Imveliso enkulu incitshisiwe indleko ukuya kwi-1/11 yexesha elidlulileyo, eCanadan Jack Johns, i-Mechanic yaseCanada, isebenzise ixesha lakhe lemoto, lasebenzisa ixesha lakhe lokutshintsha kwe-Logic enokuthi aguqule imiqondiso. Kwintlanganiso yotshintshiselwano lobugcisa, iFish (i-American Fisher) I-injini yezobuchwephesha yeNkampani ifundile malunga netekhnoloji yokutshintsha i-Jack Johns kwaye isebenzise kwicandelo lolawulo lwe-veli ngokufumana itekhnoloji ye-VOTV ngokufumana itekhnoloji ye-Voveve ngokufumana itekhnoloji yeVoti;

Kule mihla, ngokwazisa i-PLC yoLawulo lweLogic (emele i-NORBINS), abantu banokukhawuleza bakha ngokukhawuleza i-switchi-velid ye-switne ye-velid ye-velid ye-velid ye-Aute-Coace ngolwazi oluncinci lwe-Automation Loguc. Inkqubo enjalo ngoku inokukhona ikwaninzi kweemoto ezisetyenziswayo. Ngokwesiqhelo siyibiza ngokuba nguMatshini weDoosing yeVoodve (okanye umatshini wokudodobala).

Embindini we-1980s, itekhnoloji yokuNgena yeReflotenc isetyenzisiwe ngokutsha kumashishini amaninzi. Sebenzisa umgaqo-nkqubo we-frequency ukulawula iimpuphu ze-diaphragm kunokufezekisa ulawulo oluphezulu lwe-pietmacelical kuneenkqubo zangaphambili zokutyela Oku kunganceda abaphathi bam benciphisa iindleko zenkunkuma kunye neendleko zokulawula ukuya kuthi ga.

Emva kwe-1980s, iimpompo zomgama zaqala ukutshintsha kwimarike yezamashishini, ngakumbi kumacandelo eekhemikhali ezichanekileyo kunye nonyango lwamanzi. Ukusukela uyilo lwantlandlolo lwepumpling upemps yayikukusombulula ingxaki yokuphindaphinda kwaye ichanekile ekuhanjisweni kwe-uniids esemgangathweni, iimpompo zemitha ziye zasetyenziswa ngokubanzi kumzi mveliso weemineral. , iintsilelo zayo ziye zavezwa. Ezona ngxaki zinkulu zezi: 1. Uluhlu olusezantsi lokuhamba kwemveliso luncinci. Xa imali encinci isetiwe, impazamo inokuba phezulu njenge-50% okanye ngaphezulu; I-2. Idayiphragm emva kokugqabhuka, iyeza liya kuvuza; 3. Ixabiso lokuhamba libalwa ngokupheleleyo kubudlelwane obunemigca phakathi kwendlela yemoto kunye ne-pump ye-pump yentloko endaweni yenqanaba lokuhamba kweenqanawa. Kwinkqubo yokuqhubeka nokuhlengahlengisa inqanaba lokuhamba, impazamo yokuphuma kwemveliso yokuhamba iya konyuka. I-4. Ibhloko yombhobho ziya kubangela intloko yempompo ukuze iqhube phantsi koxinzelelo, kwaye imichiza evuthiweyo iya kungcolisa indalo. I-5. Iindawo zokuhlala zeFlotation ezinokungcola ngakumbi ziya kubangela i-pump ye-pump ye-pump yokutshekisha ivutha i-valve ibe yivaliwe kwaye isilele. 6. Zininzi iisekethe zokulawula ezingaphandle zangaphandle kunye nemibhobho, yokwenza ulondolozo kunye nokufakelwa kube nzima ngakumbi.

I-Italiary I-Giovanni Battista i-Venturi ifumene ifuthe le-ventnuuri isebenzisa umgaqo-nkqubo weBernoul kwaye emva koko yaqulunqa ityhubhu yeVenturi. Ngo-2013, uWillber wasebenzisa umgaqo-nkqubo weVenduri ekuhanjisweni kweerejista zeFNC kwaye wafaka i-VLB yenkqubo ye-CNC ye-CNC (Patent Not. Zl201440649261.1) Sebenzisa amandla okuqhuba ukuqhuba iikhemikhali. Inkqubo yedosi ilawulwa yisekethe egunyazisiweyo yefilimu. Ikwabizwa ngokuba ngumatshini wokutyibilika kwe-hydrodynamic.
