Carbon Slurry Cyanidation: Nzira Yekudzoreredza Goridhe kubva kuCopper Tailing

ziviso

Muindasitiri yemigodhi, kudzoreredzwa kwesimbi dzinokosha kubva mumarara kwakakosha zvikuru pakushandiswa kwezviwanikwa uye kuchengetedzwa kwezvakatipoteredza. Chidzidzo ichi chinotarisa pamugodhi wemhangura muCentral Asia, uko maitiro eCarbon -in-pulp (CIP) cyanidation akashandiswa pamarara emhangura kuti goridhe ridzorerwe.

Flotation Proces

Matope emhangura akaumbwa nesimbi akatanga kugadzirwa. Kuburikidza nemaitiro ekuumbwa nesimbi, simbi yakaumbwa nesimbi ine goridhe ye48.50 g/t uye simbi yemhangura ye8.45% yakawanikwa. Mushure mekuumbwa, simbi dzakaumbwa dzaive nesimbi yemhangura ye0.21%, pakati padzo dzaive nesimbi yecyanide inodonhedzwa nesimbi yemhangura ye0.12%.

CIP Cyanidation Maitiro

Matanda emvura akadonhera pasi akabva aiswa carbon-in-pulp cyanidation yakananga. Mukuita uku, kushandiswa kweSodium cyanide kwaive 3.1 kg/t. Mwero wekudonhera kwegoridhe wakasvika 74.71%. Mwero wekudonhera kwegoridhe kuburikidza nekusanganiswa kwekudonhera pasi nekudonhera pasi waive 88.26%, uye mwero wekudonhera kwemhangura waive 62.16%.

Mhinduro uye Benefits

Kushandiswa kweCIP cyanidation process pamhangura dzakachekwa mumhangura munyaya iyi kwakawana mhedzisiro inoshamisa. Chekutanga, yakabudirira kuwana goridhe kubva mumhangura dzakachekwa mumhangura, zvichiwedzera kugadzirwa kwegoridhe mumugodhi. Chechipiri, maitiro aya akavandudzawo mwero wekushandiswa kwezviwanikwa zvemhangura, zvichideredza kutambisa simbi dzinokosha. Pamusoro pezvo, zvichienzaniswa nedzimwe nzira dzechinyakare dzekurapa mhangura, maitiro aya ane simba shoma uye kushanda kuri nyore, izvo zvinobatsira kudzora mari uye kuchengetedzwa kwezvakatipoteredza.

mhedziso

Ichi chidzidzo chenyaya chinoratidza kuti iyo kabhoni-in-pulp cyanidation maitiro inzira inogoneka uye inoshanda yekudzoreredza goridhe kubva kumaswe emhangura. Nekugadzirisa kuyerera kwemaitiro uye paramita, chiyero chekudzoreredza chesimbi dzakakosha chinogona kuvandudzwa, zvichipa chirevo chemigodhi yakafanana mukudzoreredza zviwanikwa uye budiriro inoenderera.
