Tasiri kan Masu Tarin Ma'adinan Sulfide

Don masu tarawa da aka saba amfani da su don ma'adanai sulfide kamar xanthates da dithiophosphates, lokacin da adadin Sodium sulfide ya dace, zai iya haɓaka hydrophobicity na ma'adinai na sulfide, yana ba da damar masu tarawa don tallata mafi kyau a kan ma'adinan ma'adinai da inganta floatability na ma'adanai. Duk da haka, lokacin da sodium sulfide ya wuce gona da iri, zai samar da fim din hydrophilic a saman ma'adinan sulfide, yana hana adsorption na masu tarawa kuma don haka yana taka rawar hanawa. Misali, a cikin hawan jan karfe-sulfur tama, adadin da ya dace na sodium sulfide zai iya haɓaka tarin chalcopyrite ta xanthate, yayin da adadin da ya wuce kima zai hana flotation na chalcopyrite.

Tasiri kan Masu Tarin Ma'adinai na Oxide

A cikin yawo na ma'adinan oxide, sodium sulfide na iya sulfidize saman ma'adinan oxide, yana ba da damar tattara su ta hanyar masu tattara ma'adinai na sulfide. Misali, lokacin amfani da masu tattara fatty acid don yawo cerussite, sodium sulfide ya fara sulfidizes saman cerussite sannan yayi mu'amala da mai tattara fatty acid, yana haɓaka tasirin flotation na cerussite.

Mu'amala da Frothers

Sodium sulfide kanta ba shi da kayan kumfa, amma yana iya rinjayar kaddarorin ɓangaren litattafan almara da yanayin yanayin ma'adanai, ta haka yana tasiri tasirin kumfa na frothers. Adadin da ya dace na sodium sulfide ya sa yanayin hydrophobicity na ma'adanai ya dace, wanda ke dacewa da haɗewar kumfa zuwa ma'adanai, inganta tasirin iska da kwanciyar hankali na kumfa. Duk da haka, yawan adadin sodium sulfide zai watsar da slime mai kyau a cikin ɓangaren litattafan almara, ƙara dankon ɓangaren litattafan almara, sa kumfa ya zama m, kuma ya shafi kwanciyar hankali da ruwa na kumfa, wanda ba shi da kyau ga zubar da kumfa na flotation da kuma rabuwa da hankali.

Mu'amala da Sauran Masu Gudanarwa

Tasirin Haɗin kai tare da Ma'aikatan pH

Sodium sulfide hydrolyzes ya zama alkaline kuma yana iya aiki tare tare da sauran masu kula da pH kamar lemun tsami da sodium carbonate don daidaita ƙimar pH na ɓangaren litattafan almara. Misali, a cikin yawo na gubar-zinc tama, ana amfani da sodium sulfide da lemun tsami sau da yawa a hade don kiyaye ɓangaren litattafan almara, hana ƙazanta ma'adanai irin su pyrite, da haɓaka zaɓin flotation na gubar-zinc tama.

Ma'amala tare da Depressants

Sodium sulfide yana da irin wannan tasirin hanawa ga wasu masu damuwa irin su cyanide da gilashin ruwa. A wasu lokuta, ana iya amfani da su a hade don haɓaka tasirin hanawa. Alal misali, a cikin flotation na jan karfe-gubar-zinc polymetallic tama, hade amfani da sodium sulfide da cyanide iya ƙarfafa hana sphalerite da pyrite, cimma tasiri mai kyau rabuwa da jan karfe- gubar daga zinc-sulfur.

Ma'amala tare da Activators

Sodium sulfide yana da tasirin kunnawa akan wasu ma'adanai da aka hana kuma ana iya amfani dashi a hade tare da masu kunnawa. Alal misali, a cikin flotation rabuwa na sulfide jan karfe-guba tama, galena hana ta cyanide za a iya kunna ta sodium sulfide sa'an nan kuma tattara da ethyl thionocarbamate don cimma rabuwa da jan karfe da gubar. A lokaci guda, sodium sulfide na iya rinjayar tasirin sauran masu kunnawa. Misali, adadin da ya wuce kima na sodium sulfide na iya cinye ions masu aiki a cikin ɓangaren litattafan almara, yana rage tasirin kunnawa.

A ƙarshe, fahimtar hulɗar sodium sulfide tare da sauran reagents a cikin tsarin flotation yana da matukar mahimmanci don inganta tsarin flotation, inganta ƙimar dawowa da darajar ma'adanai masu mahimmanci, da rage farashin sarrafa ma'adinai.
