Flotation txoj kev xav ntawm kub ore

Flotation txoj kev xav ntawm kub ore

Kub yog feem ntau tsim nyob rau hauv ib lub xeev pub dawb hauv ores. Cov minerals feem ntau yog ntuj kub thiab nyiaj-kub ores. Lawv txhua tus muaj cov khoom ntab zoo, yog li cov flotation yog ib txoj hauv kev tseem ceeb rau kev ua cov kub ores. Kub yog feem ntau sib xyaw ua ke nrog ntau cov txiv ntoo sulfide. Symiotic, tshwj xeeb tshaj yog cov cim nrog rau pyrite, yog li cov flotation ntawm hlau sulfide ees xws li kub-bearing pyrite muaj feem cuam tshuam nrog kev coj ua. Cov flotation xyaum ntawm ob peb tus conforrators peb yuav qhia hauv qab no feem ntau kub ores uas kub thiab sulfide cleafist.

Nyob ntawm seb hom thiab ntau ntawm cov sulfides, cov kev kho mob hauv qab no tuaj yeem xaiv tau.
① Thaum sulfide nyob rau hauv lub ore yog pyrite yog tsuas yog pyrite, thiab tsis muaj lwm yam hnyav hlau sulfides, thiab cov kub yog hauv nruab nrab thiab cov cim thiab cov duab dub. Xws li ores tau flotated los tsim cov sulfide kub concentrates, thiab cov flotation concentrates, yog li zam kev kho Cyanidation ntawm tag nrho cov ore. Lub flotation fantrate kuj tseem tuaj yeem xa mus rau ib tsob ntoo pyrometallurgurgy. Thaum kub yog tsuas yog nyob rau hauv daim ntawv ntawm submoscopic hais thiab pyrite, thiab nws yuav tsum tau receed rau distociate cov kub hais thiab tom qab ntawd ua kom raug los ntawm huab cua.

② Thaum cov sulfides hauv cov ore muaj ib qho me me ntawm chalcopyrite, sphaalerite, thiab galie ntxiv rau ob qho tib si pyrite thiab cov pob zeb hnyav. Kev Npaj Kho Dav Hlau: Raws li cov txheej txheem tshuaj lom neeg thiab tshuaj lom neeg cov khoom siv tsis-ferrous hlau sulfide ore, ntes thiab xaiv cov kev xav tau zoo. Tus mloog zoo yog xa mus rau smelter rau kev ua. Kub nkag mus rau tooj liab lossis cov hmoov txhuas (feem ntau yog tooj liab pom) cov kev xav thiab tau zoo thaum lub sijhawm smelting. Qhov twg kub thiab hlau sulfide yog flotated tuaj yeem tau txais cov hlau sulfide mloog zoo, uas tuaj yeem zoo los ntawm kev ci thiab cua ua pauj.

Thaum muaj cov sulfides ua rau muaj kev phom sij hauv ore, xws li sulfide yuav tsum tau hlawv cov arsenic, thiab lwm yam hlau ua kom yooj yim rau cov hlau uas tsis yooj yim , Zom lub ntsej muag dua thiab siv tus cwj mem los tshem tawm cov volatile hlau oxides.

④ Thaum ib feem ntawm cov kub nyob hauv lub xeev muaj nyob rau hauv lub xeev pub dawb, ib feem ntawm Kub yog lub cim nrog sulfide, thiab ib feem ntawm cov kub hais yog impregnated nyob rau hauv gange zaub mov. Xws li cov ores yuav tsum tau rov zoo li nrog lub ntiajteb txawj nqus sib cais kom rov qab ua rau cov flotation dawb, nws yog qhov tsim nyog yuav tsum siv tshuaj lom neeg. Lub flotation mloog yuav tau zoo nyob rau hauv thiab ces lashed ncaj qha, lossis cov chaw seem hluav taws tuaj yeem ua rau hauv qab tom qab tau hlawv thiab tom qab ntawd ua pauj.
