Bayan amfani da ma'adinan sarrafa ma'adinai: A cikin tsarin flotation, ana kiran tasirin haɓaka flotability na ma'adanai ana kiransa kunnawa.Wakilin da aka yi amfani da shi don canza abun da ke cikin ma'adinan ma'adinai da inganta hulɗar tsakanin mai tarawa da ma'adinan ma'adinai ana kiransa activator.
Kunnawa za a iya raba kusan zuwa: 1. Kunnawa ta atomatik;2. Preactive;3. Tashin Kiyama;4. Vulcanization.
1. Kunna kai tsaye
Lokacin sarrafa ma'adinan polymetallic maras ƙarfe, saman ma'adinan zai amsa da sauri tare da wasu ions gishiri masu narkewa yayin aikin niƙa.Alal misali, lokacin da ma'adinan sulfide na sphalerite da jan karfe sulfide suka kasance tare, ƙananan adadin ma'adinan sulfide na jan karfe za su kasance oxidized a cikin jan karfe sulfate bayan an haƙa ma'adinan.Cu2+ ions a cikin slurry suna amsawa tare da saman sphalerite don kunna shi, yana sa ya zama da wahala a raba jan karfe da zinc.Wajibi ne a ƙara wasu ma'aikatan daidaitawa kamar lemun tsami ko sodium carbonate don hazo, da kuma wasu "ions marasa makawa" waɗanda zasu iya haifar da kunnawa.
Na biyu, preactivation
Don zaɓar ma'adinai, ƙara mai kunnawa don kunna shi.Lokacin da pyrite ya yi zafi sosai, ana ƙara sulfuric acid don narkar da fim ɗin oxide a saman pyrite kafin yin iyo, yana fallasa sabon yanayin, wanda ke da amfani ga hawan ruwa.
uku.murmurewa
Yana nufin ma'adanai waɗanda aka hana a baya, irin su sphalerite wanda cyanide ya hana, kuma ana iya tayar da shi ta hanyar ƙara sulfate na jan karfe.
Hudu.vulcanization
Yana nufin farko da magani da karfe oxide tama tare da sodium sulfide don samar da wani Layer na karfe sulfur ma'adinai film a saman oxide tama, sa'an nan yawo da xanthate.
Reagents masu sarrafa ma'adinai da ake amfani da su azaman masu kunnawa sune:
Sulfuric acid, sulfurous acid, sodium sulfide, jan karfe sulfate, oxalic acid, lemun tsami, sulfur dioxide, gubar nitrate, sodium carbonate, sodium hydroxide, gubar gishiri, barium gishiri, da dai sauransu.
