Takaitaccen nazari kan rawar da jan karfe sulfate ke yi wajen amfanar tama da tuwo

Copper sulfate, wanda ya bayyana a matsayin shuɗi ko shuɗi-koren lu'ulu'u, shine mai kunnawa da ake amfani da shi sosai a cikin sulfide ore flotation.An fi amfani da shi azaman mai kunnawa, mai sarrafawa da mai hanawa don daidaita ƙimar pH na slurry, sarrafa kumfa tsararru da inganta yanayin da ake samu na ma'adanai yana da tasirin kunnawa akan sphalerite, stibnite, pyrite da pyrrhotite, musamman sphalerite wanda aka hana ta lemun tsami. ko cyanide.

Matsayin jan karfe sulfate a cikin ma'adinai flotation:

1. Ana amfani dashi azaman kunnawa

Zai iya canza kaddarorin lantarki na saman ma'adinai kuma ya sanya saman ma'adinai hydrophilic.Wannan hydrophilicity zai iya ƙara wurin hulɗa tsakanin ma'adinai da ruwa, yana sauƙaƙa wa ma'adinan yawo.Copper sulfate kuma na iya samar da cations a cikin slurry na ma'adinai, wanda aka ƙara sanyawa a saman ma'adinan, yana ƙara yawan ruwa da buoyancy.

Tsarin kunnawa ya ƙunshi abubuwa biyu masu zuwa:

①.Halin metathesis yana faruwa a saman ma'adinan da aka kunna don samar da fim ɗin kunnawa.Alal misali, ana amfani da sulfate na jan karfe don kunna sphalerite.Radius na ion jan karfe divalent yayi kama da radius na ions na zinc, kuma solubility na jan karfe sulfide ya fi na zinc sulfide karami.Sabili da haka, ana iya samar da fim ɗin sulfide na jan karfe a saman sphalerite.Bayan an kafa fim din sulfide na jan karfe, yana iya yin hulɗa tare da mai tattara xanthate cikin sauƙi, don haka an kunna sphalerite.

②.Cire mai hanawa da farko, sannan ƙirƙirar fim ɗin kunnawa.Lokacin da sodium cyanide ya hana sphalerite, an kafa ions zinc cyanide barga a saman sphalerite, kuma ions cyanide na jan karfe sun fi kwanciyar hankali fiye da ions cyanide zinc.Idan an ƙara sulfate na jan karfe zuwa sphalerite slurry wanda cyanide ya hana, radicals cyanide a saman sphalerite za su fadi, kuma ions na jan ƙarfe na kyauta za su amsa tare da sphalerite don samar da fim ɗin kunnawa na jan karfe sulfide, don haka kunna aikin. sphalerite.

2. An yi amfani da shi azaman mai tsarawa

Ana iya daidaita ƙimar pH na slurry.A darajar pH mai dacewa, sulfate na jan karfe na iya amsawa tare da ions hydrogen akan saman ma'adinai don samar da abubuwa masu sinadarai waɗanda ke haɗuwa tare da saman ma'adinai, ƙara haɓakar hydrophilicity da buoyancy na ma'adinan, ta haka yana inganta tasirin flotation na ma'adinan zinariya.

3. An yi amfani da shi azaman mai hanawa

Ana iya samun anions a cikin slurry kuma a sanya su a saman sauran ma'adinan da ba sa buƙatar ruwa, yana rage yawan ruwa da buoyancy, don haka yana hana waɗannan ma'adanai daga shawagi tare da ma'adanai na zinariya.Ana ƙara masu hana sulfate na jan karfe zuwa slurry don kiyaye ma'adanai waɗanda ba sa buƙatar iyo a ƙasa.

4. An yi amfani da shi azaman mai gyara ma'adinai

Canja sinadarai da kaddarorin jiki na saman ma'adinai.A cikin hawan gwal na gwal, kaddarorin lantarki da hydrophilicity na ma'adinan ma'adinai sune mahimman abubuwan hawan ruwa.Copper sulfate zai iya samar da ions jan karfe oxide a cikin slurry na ma'adinai, amsa tare da ions karfe a saman ma'adinan, kuma ya canza halayen sinadarai na saman.Copper sulfate kuma na iya canza hydrophilicity na ma'adinai saman da kuma ƙara lamba yankin tsakanin ma'adanai da ruwa, don haka inganta flotation sakamako na zinariya ma'adinai.
