Abubuwan da aka saba amfani da tsarin flotation na yau da kullun don aiwatar da Ores na sarrafawa sun haɗa da fifiko mai mahimmanci, da aka gauraye da su da daidai flotation.
Duk da irin tsari ake amfani da shi, zaku sami gamuwa da matsalolin jagoran-zinc da zinc-sulfur. Makullin zuwa rabuwa shi ne m da m zabi na masu gudanarwar.
Tun lokacin da ruwa Galena ya fi na Spashite, duk hanyoyin hana zinc da kuma jagorantar iyo ana amfani da su. Maganin magunguna na magunguna don inbhibited zinc ya hada da hanyar Cyanide da kuma hanya mai kyauta. A cikin hanyar cyanide, ana amfani da sulfate zinc sulfate a hade tare da Cyanide don haɓaka tasirin infihiory. Misali, takamaiman shuka shuka yana amfani da kayan sodium da zinc sulfate a hade don rage cyanide a 20 ~ ac ko wasu ko da rage shi 3 ~ 5g / t. Aiki ya tabbatar da cewa ba kawai rage sashi ba ne, amma kuma yana kara yawan dawo da jagorar.
Don kauce wa gurasar CYANID zuwa yanayin, ana inganta hanyoyin-cyanide-kyauta ko ƙarancin cyanide a gida da kuma ƙasashen waje. Ana amfani da hanyoyin da aka saba amfani da su masu zuwa a cikin jagorar da zinc rabuwa:

Ana amfani da hanyoyin da ke sama yayin da Galena ke hadadewa da ƙarfin ƙarfinta ya zama matalauta.
Don goshin mai iyo, magani baƙar fata da xanthate galibi ana amfani dasu azaman masu tarawa, ko ethyl sulfide kadai tare da kyakkyawar salula a matsayin mai tara. Wasu tsire-tsire masu sarrafa ƙasashen waje kuma suna haɗuwa sulfosuccinic acid (A-22) tare da xanthate.
Tun da lemun tsami yana da tasirin hana shiga Galena, lokacin da akwai ɗan rubutu a cikin na, shi ne mafi ƙarancin amfani da carbonate na sodium azaman ph adjuster na PH don yin iyo. Lokacin da pyrite abun ciki a cikin raw ore yana da girma, yana da kyau a yi amfani da lemun tsami azaman ph adjuster. Saboda lemun tsami zai iya hana pyrite mai alaƙa, yana da amfani ga shugaba mai iyo.

3.Methood don zinc da sulfur
(1) iyo na iyo zincfur
1. Hanyar lemun tsami
Wannan shine mafi yawanci ana amfani da hanyar kawar da sulfur. Ana iya amfani da wannan hanyar don aiwatar da tsoma na tsoka da kuma raba zinc-sulfur Mived mai gamsarwa. Lokacin amfani da wannan hanyar, yi amfani da lemun tsami don daidaita PH, yawanci sama sama da 11, saboda an girbe pyrite. Wannan hanyar mai sauki ce, kuma sinadarai da aka yi amfani da shi shine lemun tsami, wanda yake mai arha da sauƙin samu. Koyaya, amfani da lemun tsami na iya haifar da ɗimbin kayan aikin flot, musamman fasikanci, da kuma karawar sulfur ba sauki don tace ba, sakamakon a cikin wani danshi na danshi na tattarawa.
2.Heating hanya
Ga wasu pyrites tare da babban aikin planktonic, mara nauyi ta hanyar lemun tsami ba shi da amfani. Lokacin da slurry yana mai tsanani, farfajiya na digiri na sama na sparlerite da pyrite sun bambanta. Bayan zinc-sulfultadure hade mai zafi yana mai zafi, wanda ya motsa shi, karfin pyrite ya ragu, yayin da ruwa mai tsawan lokaci ya ragu.
Bincike ya nuna cewa zinculur na iya rarrabe ta sulfur na iya rarrabawa ta tururi mai zafi don rabuwa da zinc-sulfftad ya hade. A m Matsayi zazzabi ne 42 ° C, da kuma rabawa da dumama ko ƙara kowane sinadarai na iya rarrabe zinc da sulfur. Index da aka samu shine 6.2% sama da mai maida hankali ne ta hanyar lemun tsami, kuma ragin dawo da shi shine 4.8% mafi girma.
3. Lemun tsami da karamin adadin cyanide
A lokacin da lemun tsami shi kaɗai ba zai iya murkushe baƙin ƙarfe sulfide (misali: Nacn5g / t a cikin sarrafa sarrafa hesan, nacn20g / t a cikin saina sarrafa) don inganta rabuwa da zinc-sulfur.
(2) iyo na Sulfur
Hanyar sulhu dioxide + Heam Steam Heating Wannan hanyar an yi amfani da shi a cikin SRUNsWick dalswick na ma'adinai a Kanada. Zincink na da aka samu ta shuka ya ƙunshi mai yawa pyrite. Don inganta ingancin, slurry ana bi da shi tare da gas na sulfur dioxide sannan mai zafi tare da tururi don kashe zinc zur zik da ruwa.
Hanya takamaiman hanya ita ce gabatar da gas mai gas ta sulfur ta gas daga kasan tanki na farko da kuma sarrafa PH = 4.5 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8 zuwa 4.8. A cikin Steam cikin tankuna na biyu da na uku kuma yana da shi zuwa 77 zuwa 82 ° C. Lokacin da kake son yin hoto, PH shine 5.0 ~ 5.3, kuma xanthat ana amfani da shi azaman mai tattarawa. Tutsayen flotation sune zincin zinc na zinc na ƙarshe. Baya ga pyrite, samfurin kumfa kuma ya ƙunshi zinc. Bayan da aka zaba, ana amfani dashi kamar na matsin lamba kuma ya koma zuwa ga matsakaici a gaban tsarin don regrinding. Cikakken iko na pH da zazzabi shine mabuɗin wannan aikin. Bayan jiyya, samfurin zinc ya karu daga 50% zuwa 51% zinc zuwa 57% zuwa 58%.
