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 kabhoniMaitiro ekugadzira cyanidation ye-in-pulp (CIP) akaiswa pamatavi emhangura kuti goridhe ridzorerwe.

Flotation Proces

Miswe yemhangura yakayangarara yakatanga kugadziriswa. Kuburikidza nehurongwa hwekuyangarara, flotation concentrate ine gold content ye48.50 g/t uye copper ye8.45% yakawanikwa. Mushure mekutenderera, machira aive nemhangura ye0.21%, pakati peiyo cyanide-inobatika mhangura yemukati yaive 0.12%.

CIP Cyanidation Maitiro

Iyo mitsara yakatsetseka yakabva yaiswa kune yakananga kabhoni-mu-pulp cyanidation. Mukuita uku, Sodium cyanide kushandiswa kwaiva 3.1 kg/t. The goridhe leaching rate yakasvika 74.71%. Huwandu hwekudzoreredza kwegoridhe kuburikidza nemusanganiswa wekuyangarara nekubvaruka hwaive 88.26%, uye mwero wekudzoreredza mhangura waive 62.16%.

Mhinduro uye Benefits

Iko kushandiswa kweCIP cyanidation process ku miswe yemhangura munyaya iyi yakawana migumisiro inoshamisa. Chekutanga, yakaburitsa goridhe zvine mutsindo kubva kumasara, zvichiwedzera kugadzirwa kwegoridhe rose pamugodhi. Chechipiri, hurongwa uhu hwakavandudzawo mwero wekushandiswa kwemhangura zviwanikwa, kudzikisa kuparara kwesimbi dzakakosha. Pamusoro pezvo, kana zvichienzaniswa nedzimwe nzira dzekurapa dzemachira echinyakare, maitiro aya ane simba shoma rekushandisa uye kushanda kuri nyore, izvo zvinobatsira kudzora mutengo uye kuchengetedza 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.
