Mekhoa le Mekhoa ea ho Tlosa Cyanide Bokaholimong ba Ores ea Sulfide

Cyanidation leaching ke mokhoa o sebelisoang haholo indastering ea merafo ea khauta. Leha ho le joalo, cyanidation leaching tailings hangata e baka mathata a bohlokoa. Mehatla ena hangata e na le maikutlo a tlase li-cyanides, khauta le silevera tse sa ntšoang, hammoho le liminerale tse tsamaisang thepa tse kang chalcopyrite le pyrite. Libaka tsa mafura a sulfide ka tailings tsena li thibeloa ke Sodium cyanide nakong ea ts'ebetso ea cyanidation. Le hoja boleng ba ore bo le tlase le ho cyanide mahloriso ha a phahame haholo, palo e kholo ea mehatla e etsa hore e tšoenyehe haholo.

Hajoale, ho na le mekhoa e meraro e tloaelehileng ea kalafo ea cyanidation leaching tailings: activation acid, activation ea oxidant, le koporo - kalafo ea letsoai.

Mokhoa oa ho kenya Asiti

Mokhoa oa ho kenya asiti o kenyelletsa ho eketsa sulfuric acid kapa oxalic acid ho kenya mehatla. Le hoja mokhoa ona o ka kenya li-tailings ka katleho, o na le litšitiso tse 'maloa. Taba ea pele, e tloaetse ho hlahisa khase e chefo le e kotsi ea hydrogen cyanide. Leha khase ea hydrogen cyanide e fumanoeng e ka sebelisoa hape, ts'ebetso ena e baka kotsi e kholo. Taba ea bobeli, tikoloho e nang le asiti e ka senya lisebelisoa le liphaephe habonolo, e hlokang mehato ea boemo bo holimo ea anti-corrosion.

Mokhoa oa ho kenya Oxidant

Ka mokhoa oa ho kenya oxidant, hydrogen peroxide kapa hypochlorite e eketsoa ho kenya mehatla. Leha ho le joalo, ho thata ho laola ka nepo litekanyetso tsa oxidant. Chelete e feteletseng hanyane e ka oxidize ores ea sulfide, ea fokotsa ho hlaphoheloa ha eona. Ho feta moo, li-oxidant tse ngata li senya 'mele oa motho, e leng se ka bang kotsi bophelong ba basebetsi.

Koporo - Mokhoa oa Phekolo ea Letsoai

Mokhoa oa ho phekola ka koporo - letsoai o sebelisa matsoai a sa sebetseng joalo ka koporo sulfate kapa matsoai a tšepe ho kenya mehatla. Leha ho le joalo, melao ea tikoloho e na le litlhoko tse tiileng tsa ho ntša li-ion tsa koporo metsing a litšila. Ho feta moo, li-ion tsa koporo ke li-activators tsa sphalerite le pyrite. Ka hona, mokhoa ona ha o tšoanelehe bakeng sa mehatla ea cyanidation e nang le sphalerite le pyrite, 'me ha e na tikoloho.

Qetellong, phekolo ea li-cyanidation leaching tailings e fana ka mathata a mangata. Leha ho na le litaba tse tlase tsa cyanide, litšenyehelo tse phahameng tsa matsete le litlhoko tse tiileng tsa polokeho le tikoloho li etsa hore ho hlokehe ho hlahloba mekhoa e mecha ea kalafo, e sebetsang haholoanyane le e tšoarellang. Sena se ka kenyelletsa motsoako oa mekhoa e teng kapa nts'etsopele ea mekhoa e mecha ea ho rarolla mathata a tikoloho le moruo a amanang le mehatla ena.
