Nzira Itsva Yekudzikisa Kushandiswa kweSodium Cyanide muGoridhe Concentrate Leaching

Muindasitiri yekuchera nekubvisa goridhe, kugadzirisa maitiro ekubvisa goridhe kwakakosha zvikuru nekuda kwezvikonzero zvehupfumi nezvakatipoteredza. Chimwe chinhu chakakosha kuderedza kushandiswa kweSodium cyanide mukubvisa goridhe kubva muCyanidation . Chinyorwa ichi cheblog chichaongorora maitiro matsva akaratidza mhedzisiro inoshamisa mukuzadzisa chinangwa ichi.

Kuongororwa kweSodium Cyanide Kushandiswa muCyanidation Leaching

Usati watanga nzira itsva iyi, zvakakosha kunzwisisa mamiriro aripo ekushandiswa kweSodium Cyanide mukushandiswa kwechinyakare kwecyanidation leaching. Ongororo yakadzama yekushandiswa kwecyanide panguva yekubviswa kwegoridhe yakaitwa. Sodium cyanide chinhu chakakosha mukushandiswa kwecyanidation pakuburitsa goridhe. Zvisinei, kushandiswa kwayo zvakanyanya hakungowedzeri mari yekugadzira chete asiwo kunokonzera njodzi dzezvakatipoteredza nekuda kwechepfu yayo.

Mu - zvakadzama Chidzidzo cheCyanidation Leaching Mechanism yeGoridhe Inosimbisa

Zvichienderana nekuongorora kwekushandisa, kumwe kutsvagisa kwakaitwa pamusoro peiyo cyanidation leaching meshini yegoridhe inonangana. Kunzwisisa kuti goridhe rinoita sei necyanide munzvimbo yeLeaching kwakakosha pakuvandudza maitiro anoshanda uye anodhura. Tsvakurudzo iyi yakapa ruzivo rwakakosha mukuita kwemakemikari uye maitiro emuviri anoitika panguva yeleaching, izvo zvakazoisa hwaro hwekuvandudzwa kwemaitiro matsva.

Nhanganyaya kuNzira Itsva: Kushandisa Musanganiswa weAmmonium Carbonate neAmmonium Hydroxide.

Mukupindura matambudziko ekushandiswa zvakanyanya kwe sodium cyanide , nzira itsva yakakurudzirwa. Maitiro aya anosanganisira kushandisa musanganiswa we ammonium Carbon ate ne ammonium hydroxide kuderedza huwandu hwe sodium cyanide hunodiwa. Kusanganiswa kwe reagents idzi mbiri kunogona kugadzirisa zvinobudirira mamiriro emakemikari e leaching solution, zvichikurudzira kunyungudika kwegoridhe ukuwo zvichideredza kudiwa kwe sodium cyanide.

Indasitiri Kushandisa Kudzidzira uye Migumisiro

Iko kushandiswa kwemaindasitiri kweiyi nzira itsva kwakaratidza kuita kwayo kwakatanhamara. Mukushanda kwekuita, maitiro matsva awana kudzikiswa kwekushandiswa kwe sodium cyanide neinopfuura 50%. Uku kudzikiswa kwakakosha kwakonzera zvakananga kune imwe - yetatu kuderera kwemitengo yekugadzira. Uyezve, maitiro matsva akavewo nemhedzisiro yakanaka pakudzoreredzwa kwezvinhu zvakabatana. Semuenzaniso, giredhi resirivheri mune yakasara yeleaching yakaderedzwa kusvika 15 g/t, uye sirivheri leaching rate yakawedzera ne11%. Iyi mhedzisiro haingoratidzi hupfumi hwehurongwa hutsva asiwo kugona kwayo kwekuwedzera kwekushandisa zviwanikwa.

Mukupedzisa, maitiro matsva ekushandisa musanganiswa weammonium carbonate neammonium hydroxide kuderedza kushandiswa kwe sodium cyanide muGold concentrate leaching ibudiriro huru muindasitiri yekubvisa goridhe. Inopa mhinduro inodhura uye isingakuvadzi nharaunda, iyo inotarisirwa kushandiswa zvakanyanya mune ramangwana.
