Lokacin da aka ƙara jan ƙarfe sulfate a cikin slurry na sphalerite wanda cyanide ya hana, radicals na cyanide a saman sphalerite suna faɗuwa, kuma ions na jan ƙarfe masu 'yanci suna amsawa da sphalerite don samar da fim ɗin kunnawa na jan ƙarfe sulfide, ta haka suna sake kunna sphalerite don flotation.

Tsarin Slurry pH

Copper sulfate kuma yana aiki azaman mai tsarawa a cikin slurry sarrafa ma'adinai, musamman dangane da daidaita pH. Ƙimar pH na slurry wani abu ne mai mahimmanci wanda ke shafar kaddarorin saman ma'adanai da aikin reagents na flotation.

Lokacin da jan karfe sulfate aka kara zuwa slurry, shi zai iya sha hydrolysis a cikin ruwa. Sakamakon sulfuric acid zai iya ƙara yawan ƙwayar hydrogen ion a cikin slurry, don haka rage darajar pH. A ƙimar pH da ta dace, sulfate na jan karfe na iya amsawa tare da ions hydrogen akan saman ma'adinai don samar da abubuwan sinadarai waɗanda ke haɗuwa da saman ma'adinai. Wannan halayen na iya ƙara haɓakar hydrophilicity da buoyancy na ma'adinai, inganta tasirin flotation. Alal misali, a cikin wasu zinariya - ma'adanai masu ɗaukar nauyi, daidaitawa pH na slurry tare da jan karfe sulfate na iya haɓaka hulɗar da ke tsakanin zinariya - ma'adanai da masu tarawa, inganta farfadowa na flotation na zinariya.

Copper sulfate na iya aiki azaman mai gyara ma'adinai, yana canza 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 da ke shafar ingancin ruwa.

A cikin slurry ma'adinai, jan karfe sulfate zai iya samar da jan karfe - dauke da ions. Wadannan ions na iya mayar da martani da ions karfe a saman ma'adinan, suna canza halayen sinadarai na saman. Misali, a saman wasu zinare - ma'adanai masu ɗauke da wani nau'in oxide, jan ƙarfe - mai ɗauke da ions na iya amsawa tare da ions na ƙarfe a cikin Layer oxide, suna samar da sabbin sinadarai a saman. Wannan zai iya canza cajin saman da kuma amsawar sinadarai na ma'adinai.

Haka kuma, jan karfe sulfate kuma iya rinjayar da hydrophilicity na ma'adinai saman. Ta hanyar haɓaka wurin hulɗa tsakanin ma'adanai da ruwa, zai iya inganta yaduwar ma'adanai a cikin slurry. Wannan ingantaccen tarwatsawa zai iya zama da fa'ida ga aikin masu tarawa na gaba.
