Makiyi Tekinoroji eKurasa Kusingakuvadzi kweGoridhe Concentrate Cyanide Residue

Iyo cyanidation process yekuchera goridhe, ichizvikudza nhoroondo yemakore anopfuura zana, ichiri kuitika mukugadzirwa kwazvino kwegoridhe mumaindasitiri. Kuzivikanwa kwayo kunobva mukureruka kwayo uye yakakwira goridhe kudzoreredza mwero. Zvakadaro, nzira iyi inoburitsa huwandu hukuru hwemachira egoridhe. Kubuda kwe cyanide zvisaririra zvegoridhe zvakasara zviri kuwedzera gore negore. Huwandu hunoratidza kuti indasitiri yegoridhe yenyika inoburitsa matani anosvika mamirioni makumi masere kusvika kumamiriyoni zana ezvisaririra zvecyanide gore rega rega.

Kuchengetwa kwenguva refu kweaya masara ecyanide kunogadzira matambudziko akawanda. Chekutanga, inotora nzvimbo yakakura kwazvo. Chechipiri, iyo yakanyanya chepfu cyanides mune zvisaririra zvinogona kuburitsa magasi ane muchetura uye kugadzira acidic wastewater. Pamusoro pezvo, maion akasiyana esimbi anogona kusvibisa miviri yemvura yakatenderedza uye ivhu kuburikidza nemvura yepamusoro kana pasi pevhu, zvichiisa hutano hwevanhu pangozi. Zvinoshamisa kuti, masara ecyanide kubva kugoridhe ane zviwanikwa zvakakosha seCu, Pb, Zn, Fe, Au, S, uye Si izvo zvinosara zviri pasi - zvakadzoserwa. Nekudaro, kupatsanura zvakachengeteka zvinhu zvine chepfu, kuparadzanisa zvine mutsindo uye kudzoreredza zviwanikwa zvakakosha, uye kuwana hukuru-hukuru hwekushandisa de - cyanided tailings zvave zvekutanga kutsvagisa uye matambudziko.

United Chemical Co., Ltd.'s Solution: A Holistic Project

Mukupindura matambudziko aya, United Chemical Co., Ltd. yakatanga chirongwa che "Ongororo neKushandisa Makiyi Tekinoroji eKurasa Kusina Kukuvadza uye Kushandiswa Kwezviwanikwa zveCyanide Residues kubva kuGoridhe Concentrates".

Gradient - Inodzorwa De - cyanidation uye Flotation Recovery

Iyo "Tekinoroji Itsva yeGradient - Inodzorwa Kubvisa - cyanidation uye Flotation Kudzoreredza Kwezvinhu Zvinokosha" yakagamuchirwa kuti idzorere zvizere Cu, Pb, uye Zn kubva kugoridhe cyanidation tailings. Nekuda kweizvozvo, mutobvu wakanyanya uye mhangura dzakasimba dzakagadzirwa.

Pyrite Interface Activation uye Yakasanganiswa Kugadziriswa kweIron uye Goridhe Kudzoreredza

Zvadaro, "Tekinoroji Itsva yePyrite Interface Activation uye Yakasanganiswa Mineral Processing uye Metallurgy yeIron uye Goridhe Recovery" yakaitwa. Iyi tekinoroji yakapatsanura zvakanaka uye yakadzoreredza Fe neSi kubva kune de-cyanidated flotation tailings, ichiburitsa sulfur concentrates uye yakakwirira-silicon tailings.

Sulfuric Acid uye Iron Pellet Kugadzirwa

Sulfur concentrates yakashandiswa kugadzira concentrated sulfuric acid kuburikidza nekushaya simba - kugocha okisijeni. Iyo yakagochwa sarufa slag yakatemwa. Mushure mezvo, iyo "Yakakwira - Temperature Iron - Gold Separation Technology" yakashandiswa kugadzira simbi pellets uye dhaka regoridhe rakafumiswa neCu, Pb, uye Zn.

Yakakwirira - Silicon Tailings Recycling

Iyo "Tekinoroji Itsva yeChikamu - Shandura Regulation uye Yakazara - Chikamu Kudzokorodza Yepamusoro - Silicon Tailings" yakagonesa kushandurwa kweakakwira - silicon tailings kuita European - maitiro anovharira ceramic mataira.

Tekinoroji uye Tsvagiridzo Mabudiro

Iyi purojekiti yakagadzirisa "zvina zvakaoma" zvine chekuita necyanide zvisaririra kubva mugoridhe zvinonangana: kunyatsonzwisisa zvinhu zvine chepfu, kudzora uye nekuparadzanisa maitiro avo, kudzoreredza zvinhu zvakakosha, uye kudzoreredza miswe. Yakaunza nzira itsva yekudyidzana, kubatanidza mineral processing, metallurgy, uye sainzi yezvakatipoteredza. Tsvagiridzo iyi yakatambanudzira cheni yese yekuvandudza, kubva pakufumura zvikonzero zvesainzi kusvika pakuvandudza matekinoroji ekudzora uye kuita zviratidzo zveinjiniya.

Pamberi pesainzi uye tekinoroji, yakaratidza zvakarongeka maitiro ezvinoitika zvechepfu mucyanide - ine tsvina ine muchetura ine ngozi. Padanho rekushandisa, yakagadzira matekinoroji ekuparadzanisa kwakachengeteka uye kuraswa kwakadzikama kwezvinhu zvine chepfu, kudhirowa kwakarongeka kwezvinhu zvakakosha, uye kushandiswa kwepamusoro-ukoshi hwematailings zviwanikwa.

Inonakidza Indasitiri Yekushandisa Mhedzisiro

Mushure mekushandiswa kwemaindasitiri kwezvakabudirira zvepurojekiti, mwero wekudzoreredza kwesimbi dzakakosha kubva kune cyanide zvakasara zvegoridhe zvakapfuura 90%. Chiitiko ichi chakaitika Kurasa kusina ngozi uye zvizere - chikamu Shandiso yekushandisa ye cyanide zvakasara kubva mugoridhe concentrates. Pagore, chirongwa ichi chaigadzira anenge 8.000 matani ega ega emutobvu anonangana nemhangura, pamusoro pe300.000 matani epamusoro - sulfur concentrate, pamusoro pe200.000 matani eiyo concentrated sulfuric acid uye oxidized pellets, angangoita 700 kg yegoridhe, uye anopfuura 90 miriyoni ekubatanidza matiles eEuropean. Sezviri pachena, chirongwa chacho chakaunza zvikomborero zvinoshamisa mune zvoupfumi, zvakatipoteredza, uye munzanga.
