Yese madhaka cyanide leaching inzira yekare uye yakavimbika yekubvisa goridhe, iyo inoshandiswa zvakanyanya mukugadzira nhasi.Mumakore achangopfuura, kuti uwedzere kugadzirwa kwegoridhe, kuona kugadzirwa kwegoridhe panzvimbo, uye kuwedzera kugadzirwa kwemabhizinesi, migodhi yegoridhe yakasiyana-siyana yakawedzera chiyero chekushandisa kwese-madhaka cyanide leaching process.
Zvimedu zvakamisikidzwa zvegoridhe mune akasiyana ores kazhinji ari epakati uye akakwenenzverwa goridhe, uye kuitika kwegoridhe kunonyanya kuve intergranular goridhe uye fissure goridhe.Iyi yakamisikidzwa nyika inoita kuti izere madhaka cyanide leaching, asi kuchine hunyoro hunyoro hwematumbu akaputirwa negoridhe mune akasiyana ores, ayo anove nekumwe kukanganisa pakudonha kwegoridhe.Mhedzisiro yetsvakiridzo yemaminerari inoratidza kuti mhando yega yega isimbi yakaoma yegoridhe kudonha, uye yakawanda cyanide inopedzwa panguva yecyanide leaching, iyo inokanganisa kuwanda kwegoridhe.
Iyo yakajairwa ese-madhaka cyanide leaching maitiro haangopedza yakawanda cyanide, asi zvakare ine yakaderera leaching mwero wepakati- uye yakakwira-sulfide ores yegoridhe ine yakawanda tsvina inokuvadza semhangura, arsenic, uye sulfur.Kuwedzera lead nitrate yepretreatment isati yadonha inogona kuderedza kurasikirwa kwecyanide uye kuwedzera chiyero cheleaching.
Kuwedzera lead nitrate kusati kwadonha kunogona kuderedza zviri mukati mesimbi inonyungudika zvidimbu mu slurry, nokudaro kuderedza sodium cyanide kushandiswa.Mumigodhi yegoridhe, tora ore-mhando yepamusoro-flavor pyrrhotite-mhando yegoridhe-2-copper ore semuenzaniso.Zvinyorwa zve pyrrhotite zvinosvika 23130%.Mumamolecular chimiro chepyrrhotite, pane atomu isina kusimba yakasungwa nesarufa iyo inonatswa nyore oxidized kuita soluble sulfide, iyo inoshandisa yakawanda cyanide panguva yecyanide leaching process uye inorebesa nguva yepreatment.Uye kuwedzerwa kwe lead nitrate kunogona kuderedza kuvapo kwe sulfide ions mu slurry uye yakagadzika soluble sulfide, nokudaro kuderedza kushandiswa kwe sodium cyanide uye kuvandudza chiyero cheleaching.
