Likopo le Bohlokoa ba Sodium Cyanide Ts'ebetsong ea Liminerale

Sodium cyanide, motsoako oa inorganic, o bapala karolo ea bohlokoa ts'ebetsong ea cyanidation ka har'a indasteri ea merafo ea khauta. Tšebeliso ea eona e fapane ebile e bohlokoa ho ntšoa ha litšepe tsa bohlokoa ho tsoa ho ores.

Khauta Ore Leaching

E 'ngoe ea lisebelisoa tsa mantlha tsa Sodium cyanide e ka har'a leaching ea tšepe ea khauta. Ts'ebetsong ena, ore ea khauta, ka mor'a hore e siloe ebe e siloa hore e be likaroloana tse ntle, e kopana le motsoako o nang le metsi a nang le metsi. Sodium cyanide. Karabelo ea lik'hemik'hale e etsahala pakeng tsa sodium cyanide le khauta ka har'a tšepe, e leng se fellang ka ho thehoa ha li-ion tsa khauta tsa cyanide, tse ntan'o qhibiliha ka tharollo. Ts'ebetso ena, e tsejoang e le Leaching ea cyanide, ke mohato oa bohlokoa le oa bohlokoa molemong oa ho rua molemo oa khauta. Equation ea lik'hemik'hale bakeng sa karabelo lipakeng tsa khauta, oksijene, le sodium cyanide ka tharollo ea metsi e ka nolofalloa joalo ka: 4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH. Karabelo ena e lumella khauta, eo hangata e leng teng maemong a tlase a ore, ho qhibiliha le ho arohanngoa le liminerale tse ling.

Khauta ea Khauta

Ka mor'a ts'ebetso ea cyanide leaching, tharollo e nang le khauta e qhibilihisitsoeng e bokelloa 'me e behoa tlas'a phekolo e eketsehileng ho fokotsa khauta. Sodium cyanide e sebetsa e le precipitant sethaleng sena. E kopana le li-ion tsa khauta tsa chloride tharollong ea ho etsa li-complex tsa khauta tsa cyanide. Ka mor'a moo, ho sebelisoa mekhoa e sa tšoaneng ho ntša khauta mehahong ena. Mokhoa o mong o tloaelehileng ke tšebeliso ea lerōle la zinki kapa lisebelisoa tse ling tse fokotsang. Zinc e tlosa khauta sebakeng sa khauta ea cyanide, e bakang pula ea khauta ea tšepe. Maikutlo a ka hlahisoa joalo ka: 2Na[Au(CN)₂] + Zn → 2Au + Na₂[Zn(CN)₄]. Ts'ebetso ena e thusa ho khutlisa khauta e hloekileng ho tsoa tharollong ea leach.

Leaching of Other Metal Ores

Ka holim'a khauta, sodium cyanide e boetse e fumana ts'ebetso ho leaching ea ores e meng ea tšepe. Ka mohlala, tabeng ea ores ea silevera, ka mor'a hore cyanide leaching, sodium cyanide e sebelisoe e le moemeli oa ho ntša silevera ho tsoa tharollo. E ts'oanang le Khauta e ntšoangn ts'ebetso, silevera e etsa li-cyanide complexes ka pel'a sodium cyanide. Boitšoaro pakeng tsa silevera, sodium cyanide, le oksijene ka tharollo ea metsi e tšoana le ea khauta: 4Ag + 8NaCN + O₂ + 2H₂O → 4Na[Ag(CN)₂] + 4NaOH. Lisebelisoa tsena tsa silevera tsa cyanide li ka sebetsoa hape ho fumana silevera ea tšepe.

Qetellong, sodium cyanide ke k'hemik'hale ea bohlokoa haholo Ts'ebetso ea liminerale indasteri, haholo-holo ha ho ntšoa litšepe tsa bohlokoa tse kang khauta le silevera. Leha ho le joalo, ke habohlokoa ho hlokomela hore ka lebaka la tlhaho ea eona e chefo haholo, mehato e tiileng ea tšireletso le tšireletso ea tikoloho e tlameha ho kenngoa ts'ebetsong nakong ea tšebeliso ea eona mesebetsing ea merafo ho thibela kotsi leha e le efe bophelong ba batho le tikolohong.
