Makiyi Tekinoroji eKurasa Kusingakuvadzi kweGoridhe Concentrate Cyanide Residue

Maitiro ekugadzira goridhe ne cyanidation, ane nhoroondo yemakore anopfuura zana, achiripo mukugadzirwa kwegoridhe pari zvino. Kufarirwa kwayo kunobva mukureruka kwayo uye mwero wepamusoro wekudzoreredza goridhe. Kunyange zvakadaro, maitiro aya anogadzira huwandu hwakawanda hwegoridhe. Kubuda kwe cyanide residues kubva mugoridhe concentrates kuri kuwedzera gore rega rega. Nhamba dzinoratidza kuti indasitiri yegoridhe yenyika inogadzira matani angangoita mamiriyoni makumi masere kusvika zana emarita e cyanide residues gore rega rega.

Kuunganidzwa kwenguva refu kwezvisaririra zvecyanide izvi kunokonzera matambudziko akawanda. Chekutanga, zvinotora nzvimbo yakakura kwazvo. Chechipiri, macyanide ane chepfu yakawanda ari mumasaririra anogona kuburitsa magasi ane chepfu uye kugadzira mvura ine acidic. Pamusoro pezvo, maion akasiyana-siyana esimbi anogona kusvibisa nzvimbo dzemvura nevhu dzakapoteredza kuburikidza nemvura yepamusoro kana pasi pevhu, zvichiisa hutano hwevanhu panjodzi. Zvinoshamisa kuti, masara ecyanide kubva mugoridhe ane zviwanikwa zvakakosha zvakaita seCu, Pb, Zn, Fe, Au, S, uye Si izvo zvinoramba zvakawanikwa. Saka, kuparadzanisa zvine chepfu zvakachengeteka, kuparadzanisa uye kudzosa zviwanikwa zvinokosha zvinobudirira, uye kuwana kushandiswa kukuru kwetsvina isina cyanided kwave kuri kukoshesa kutsvagurudza kwepasi rose nematambudziko.

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 kwepurojekiti iyi mumaindasitiri, huwandu hwesimbi dzinokosha dzakawanikwa kubva muzvimedu zvecyanide zvegoridhe zvakapfuura 90%. Izvi zvakabatsira pakurasa zvisina njodzi uye kushandiswa kwezviwanikwa zvecyanide kubva muzvimedu zvegoridhe. Gore rega rega, chirongwa ichi chakagadzira matani angangoita 8.000 emhando yelead concentrates necopper concentrates, matani anopfuura 300.000 e high-sulphur concentrates, matani anopfuura 200.000 e sulfuric acid ne oxidized pellets, anenge 700 kg yegoridhe, uye mataira anopfuura mamiriyoni 90 eEuropean interlocking style. Zviri pachena kuti chirongwa ichi chakaunza mabhenefiti anoshamisa ehupfumi, zvakatipoteredza, uye magariro evanhu.
