Imiphumela ye-Ultrasonic ku-Precipitation ne-Froth Flotation

Amanzi emfucumfucu yezimboni avame ukugcotshwa kakhulu ngenxa yokusetshenziswa ngokweqile kwe-sulfuric acid. Amanzi amdaka ahlanganisiwe aqukethe izinsimbi ezisindayo zivame ukuphathwa ngokuqothuka kwamakhemikhali ngemuva kokubumbana nokuntanta. Ukulungiswa kwesimo se-Ultrasonic ngaphambi kwe-flotation kuholele ekunciphiseni okukhulu kwe-zinc hydroxide eyenziwe ngesikhathi kwezulu. Ngaphezu kwalokho, i-sonication iphinde yathuthukisa ukususwa kwemishini kwe-zinc hydroxide ezindaweni eziphezulu zezinhlayiya ze-gypsum.

I-Froth Flotation kanye ne-Ultrasonic Conditioning

Izinhlayiya ezinhle ziletha izinkinga ezikhethekile ekuhlangeni. Ukutakula kuvame ukwehla ngaphansi kosayizi othile obuhlakaniwe. Umsebenzi wakuqala owenziwa nguGaudin nalabo osebenza nabo (1931) bakhombisa ukuthi ukubuyiselwa kwamaminerali we-zethusi okuyi-iron. I-zinc nomthofu kuphezulu, > I-95% ebangeni lobukhulu bezinhlayiyana ze-10-100 µm, kodwa ngaphansi kwe-10 µm okubuyayo kwehlela ebangeni 70-85%. AbakwaTrahar noWarren (1976) bafingqe amabanga osayizi abonwayo wokubuyiselwa okuphezulu kwamaminerali amaningi fl oated ngaphansi kwezimo ezijwayelekile zokuhlola. Amabanga osayizi ezimweni eziningi anwetshiwe ngokushintsha izimo nokuphathwa kabi kwamakhemikhali wamakhemikhali nawomzimba.
I-Sonication iyindlela ephumelelayo yokwelashwa yokususa izinsimbi ezisindayo ezinjenge- iron, i-zinc ne-zethusi emiseleni yezimayini ze-acid nezinye izinto zensimbi.

ukushisa kwe-ultrasonic

I-Ultra Power isetshenziswa kabanzi ukususa ukungcola kumaminerali. Ucwaningo luye lwabonisa ukuthi i-sonication ikhuthaza ukususwa kwe-zinc kusuka kuma-hydroxide precipitates, kanye nokuhlukaniswa kwe-zinc hydroxide kanye ne-gypsum precipitates yi-encibilikisiwe yomoya. Kusetshenziswa i-carboxy-methyl cellulose (CMC) njengedepho yamaminerali e-calcium oxide ku-flotation, ucwaningo selufakazisile ukuthi i-sonication ithuthukisa ukususwa kwemishini kwe-zinc hydroxide ebusweni bezinhlayiya ze-gypsum.

Ukwelashwa kwangaphambili kwe-Ultrasonic ngaphambi kweseli le-Denver flotation kukhulisa ukususwa kwe-zethusi (i-Cu) ekudonselweni emayini kwe-acid.

Ukuqhathanisa ukususwa kwethusi ngokumelene nesikhathi kwikhambi labo phakathi kokuhlanganiswa kokulashwa kwangaphambi kwe-ultrasonic neseli le-Denver, isitokisi seDenver kuphela, nokusetshenziswa kanyekanye kwe-ultrasound neDenver flotation cell. (Ishak & I-Rowson 2009)

Imiphumela ye-Ultrasonic ku-Flotation

U-Ishak noRowson (2009) bakhombisa ukuthi ukwelashwa kwangaphambi kwe-ultrasonic kuthuthukisa ukukhishwa kwezinsimbi ezisindayo (okungukuthi, i-iron, i-zinc, ne-zethusi) emgodini wokudonsa i-acid lapho kuhlanganiswa nohlelo lwe-flotation. Ocwaningweni, kwakusetshenziswa iseli leDenver Flotation. Bathole ukuthi i-sonication kusenesikhathi sokuqala sokwelashwa kwe-ultrasonic, okuyi-2 imizuzu yokuqala yesikhathi se-flotation, isebenza kakhulu futhi inikeza imiphumela engcono kakhulu ye-flotation ethuthukisiwe. Ngokulashwa okuhlanganisiwe kwe-Power-ultrasound neseli le-Denver flotation, kuze kube ngu-3% wokususa umehluko kutholakale ngokuqhathaniswa neseli iDenver yodwa. I-pH efanelekile yensimbi ukucacisa futhi umthamo olungile wefrimu efanelekile kungenye yezinto ezifakayo empumelelweni yenqubo yokufiphaza eyenziwe ngcono.

Ukwelashwa kwangaphambili kwe-Ultrasonic ngaphambi kweseli le-Denver flotation kukhulisa ukususwa kwensimbi (Fe) kusuka emayini yedamu le-acid.

Ukuqhathaniswa nokususwa kwe-iron (Fe) ngokumelene nesikhathi kwikhambi labo phakathi kwenhlanganisela yokwenziwa kwangaphambi kokulashwa kwe-ultrasonic neseli yeDenver, iseli leDenver kuphela, nokusebenzisa kanyekanye kwe-ultrasound neDenver flotation cell. (Ishak & I-Rowson 2009)

Ukwelashwa kwangaphambili kwe-Ultrasonic ngaphambi kweseli le-Denver flotation kukhulisa ukususwa kwe-zinc (Zn) kusuka emayini yemayini ye-acid.

Ukuqhathanisa ukususwa kwe-zinc (Zn) ngokumelene nesikhathi kusixazululo sabo phakathi kwenhlanganisela yokwenziwa kwangaphambi kokulashwa kwe-ultrasonic neseli yeDenver, iseli iDenver iyodwa, nokusebenzisa kanyekanye kwe-ultrasound neDenver flotation cell. (Ishak & I-Rowson 2009)

Ukusebenza okuphezulu kwe-Ultrasonicators

UIP4000hdT flow flow cell for sonication inline esikalini ezimboniniI-Hielscher Ultrasonics ngumlingani wakho wesikhathi eside onolwazi uma kuziwa ekusebenzeni okukhulu kokusebenza kwe-ultrasonic. Ukumboza ububanzi obugcwele kusuka kuma-compact lab ultrasonicators kuya kuma-processor we-bench-top processors kuze kufike ezinhlelweni ze-ultrasonic zezimboni ngokugcwele, i-Hielscher ikunikeza imishini efanelekayo kakhulu ye-ultrasonic yohlelo lwakho lokusebenza. Ngezinqubo ezinjengefracation ye-froth, ukuhlanza komhlaba kuyizinhlayiyana, ama-ultrasonicators aphezulu we-Hielscher angamadivayisi athembekile, asebenza ngokuthembekile angama-24/7 ngaphansi kwemithwalo esindayo nasezindaweni ezifunwayo. Hielscher Ultrasonics’ ama-processor ultrasonic processors angahambisa ama-amplopes aphezulu kakhulu. Amandla okufika ku-200µm angaqhutshwa kalula ekusebenzeni okuqhubekayo kwe-24/7. Ukulawulwa okuqondile kwemingcele yenqubo ye-ultrasonic, ukulungiswa okulula kwepharamitha nokulungiswa kwesikrini sokuthinta noma isilawuli kude sesilawuli kude, ukuqoshwa kwedatha okuzenzakalelayo ekhadini le-SD elakhelwe ngaphakathi nokushisa kwe-plug-in kanye nezinzwa zokucindezela kuqinisekisa ubungani bomsebenzisi, ukuphuma kwekhwalithi ephezulu nokuvumelana okungaguquki ikhwalithi yomkhiqizo.
Amakhasimende ethu anelisekile ngokuqina okuqinile nokuthembeka kwezinhlelo zikaHielscher Ultrasonic. Ukufakwa emikhakheni yesicelo esisebenza kanzima, izindawo ezifunwayo kanye nokusebenza kwe-24/7 kuqinisekisa ukucutshungulwa okusebenzayo nokunempilo. Ukuqina kwenqubo ye-Ultrasonic kunciphisa isikhathi sokucubungula futhi kufinyelela imiphumela engcono, ie izinga eliphakeme, isivuno esiphakeme, imikhiqizo emisha.
