Iko Kushandiswa Kwezvose - Slime Cyanidation Oxygen - Rich Leaching Process

ziviso

Muindasitiri yekuchera nekubvisa goridhe, nzira yekubvisa goridhe kubva mumatombo yagara iri nzira inoshandiswa zvakanyanya pakubvisa goridhe kubva mumatombo. Maitiro aya anotanga nekukuya dombo rese kuita zvidimbu zvidiki, kazhinji nechikamu chakakura chezvidimbu zvidiki pane 74 micrometers (-200 mesh). Slurry inobuda inobva yabatwa necyanide . Maion eCyanide anoita negoridhe mumatombo, achigadzira makemikari egoridhe anonyungudika. Mamakemikari aya anogona kugadziriswa zvakare kuti awane goridhe.

Chinhu chakakosha pakuvandudza nzira yekubvisa tsvina kubva muslime cyanidation ndechekuisa leaching ine oxygen yakawanda. Kuvandudzwa uku kwakaratidza mukana mukuru mukuvandudza kushanda zvakanaka uye kushanda kweGold extraction.

Nheyo yeOkisijeni - Yakapfuma Yakawedzera Cyanide Leaching

Iyo oxygen - yakawanda yakawedzera goridhe leaching process, inozivikanwawo seCIG oxygenation process, inotsiva tsika yechinyakare yekushandisa mweya wakadzvanywa mutangi rekuleaching neokisijeni yakachena. Kana okisijeni yakachena ikaunzwa mutangi inoregedza ichibva pasi pemujenya, inonyungudika muore slurry. Nheyo yakakosha ndeyekuti kunyungudika kwegoridhe mucyanide mhinduro kunoitika kuburikidza ne electrochemical reaction. Okisijeni inoshanda seanoxidizing agent, iyo inobatsira kunyungudutsa goridhe zvakanyanya.

Zvizhinji zvinomera zvecyanide zvinoshanda pasi pemamiriro ezvinhu apo chiyero che cyanide ions kune oxygen yakakura kudarika 6. Mumamiriro ezvinhu akadaro, kukurumidza kwekunyunguduka kwegoridhe kunobva pakuti okisijeni inogona kupararira nokukurumidza sei mukuita. Nekushandisa okisijeni yakachena, huwandu hweokisijeni yakanyungudika mune slurry inowedzera, iyo inomhanyisa kuita kwese. Tsvagiridzo inoratidza kuti goridhe rinodonha neokisijeni rinomhanya zvakapetwa kashanu pane nemhepo.

Zvakanakira zveOkisijeni - Yakapfuma Leaching mune Zvese - Slime Cyanidation

1. Kuwedzera Leaching Speed ​​uye Recovery Rate

Iyo yakakwira okisijeni yemukati mune slurry inotungamira kune inokurumidza leaching kumhanya. Nekukurumidza kupera kwegoridhe, iyo yakazara leaching nguva inogona kuderedzwa zvakanyanya. Izvi hazvingokwidzi simba remazuva ese ekugadzira chirimwa asi zvakare zvinoita kuti kutorwa kwegoridhe kubva mumatombo kwakanyatsoshanda. Nekuda kweizvozvo, mwero wekudzoreredza goridhe unogona kuvandudzwa, zvichitungamira kune goho repamusoro resimbi yakakosha iyi.

2. Yakaderedzwa Cyanide Kushandiswa

Kushandisa okisijeni yakachena mukubviswa kwechinhu ichi kunogona kuderedza kushandiswa kweCyanide ne5% kusvika 85%. Pane zvikonzero zvakawanda zveizvi. Chekutanga, kana okisijeni yakachena ikashandiswa panzvimbo pemhepo, huwandu hweCarbon dioxide muslurry hunoderera. Carbon dioxide inogona kuita necyanide, zvichiita kuti ishandiswe mukushandiswa kwechinhu ichi. Kana carbon dioxide shoma, kushandiswa kwechinhu ichi kunoderedzwa. Chechipiri, kukurumidza kubudiswa kwechinhu ichi kunoderedza simba rekushandiswa kwechinhu ichi chinodyiwa necyanide. Chechitatu, okisijeni yakachena inogona kuoxida zvinhu zviri muore izvo zvaizodyiwa necyanide, zvichideredza huwandu hwecyanide hunodiwa pakubviswa kwechinhu ichi.

3. Diki Equipment Zvinodiwa

Kana iyo leaching simba ikaramba isina kuchinjika, oxygen - rich leaching inogona kuderedza zvakanyanya saizi yeleaching tank. Nekuti kukurumidza kudonha kwechiyero kunobvumira yakaenzana goridhe kuti igadziriswe munguva pfupi, diki rekuita vhoriyamu rinokwana. Kudzikisira saizi yemidziyo yekuregedza kunogona kutungamira mukuchengetwa kwemutengo maererano nekutenga michina, kuisirwa, uye nzvimbo yese inodiwa neinogadzirisa chirimwa.

Nyaya Dzokushandisa

Mhosva 1: 

yakamboshandiswa yechinyakare zvese - slime cyanidation process ine air aeration. Nekuda kwekuoma kwakaoma kweore, kuwana yakakwirira goridhe kudzoreredza mitengo yaive dambudziko. Mushure mekuita zvese - slime cyanidation oxygen - yakapfuma leaching process, kuvandudzwa kunoshamisa kwakaonekwa. Nguva yekucheka yakave nepakati, uye chiyero chekudzosa goridhe chakawedzera kubva pa80% kusvika pa90%. Pamusoro pezvo, kunwiwa kwecyanide kwakadzikira ne30%, zvichikonzera kuchengerwa kwemitengo yemugodhi.

Mhosva 2: 

mugodhi muhombe wegoridhe une hunyanzvi hwekugadzirisa vhoriyamu. Nekutora iyo okisijeni - yakapfuma leaching process mune yavo yese - slime cyanidation system, vakakwanisa kuwedzera kugadzirwa kwavo kwegoridhe kwemazuva ese ne20%. Mugodhi uyu wakataurawo kudzikiswa kwemitengo yese yekushandisa, zvakanyanya nekuda kwekudzikira kwekushandisa cyanide uye nekushandisa zvakanaka michina. Kuitwa kwakabudirira pa[Mine Name 2] kunoshanda semuenzaniso wemimwe migodhi mudunhu iri kuti ifunge kuvandudza nzira dzekuchera.

Matambudziko uye Mhinduro muKushandisa Oxygen - Yakapfuma Leaching

1. Zvekuchengetedza Zvinetso

Kubata yakachena okisijeni kunoda yakasimba kuchengetedza mapuroteni. Oxygen inonyanya kushandiswa, uye kubata kusina kunaka kunogona kukonzera moto kana kuputika. Kuti zvigadzirise izvi, migodhi inofanirwa kuisa mari mukuchengetera mweya weokisijeni uye masisitimu ekutumira anoenderana nemitemo yekuchengetedza. Kugara uchidzidziswa kuchengetedza vashandi vanobatanidzwa muokisijeni - yakapfuma leaching process yakakoshawo kuona kuti vanonzwisisa njodzi dzinogona kuitika uye mashandisiro akachengeteka michina ine hukama neokisijeni.

2. Equipment Compatibility

Kukwidziridza kune okisijeni - yakapfuma leaching system ingangoda kugadziridzwa kune iripo leaching michina. Zvishandiso zvinoshandiswa mukuvaka matangi ekuleaching, agitators, uye mapaipi zvinoda kuenderana neokisijeni kudzivirira kukora uye kuve nechokwadi chekushanda kwenguva refu. Mune zvimwe zviitiko, zvingave zvakakosha kutsiva zvimwe zvikamu neokisijeni - inodzivirira zvinhu sesimbi isina tsvina kana mapolymer akasarudzika.

3. Mutengo weOxygen Supply

Mutengo wekuwana nekupa oxygen yakachena unogona kunetsa kune mimwe migodhi. Nekudaro, iyo inochengetwa kubva mukuderedzwa cyanide kushandiswa uye kuwedzera goridhe kudzoreredza mitengo inowanzopfuura mutengo weokisijeni munguva refu. Migodhi inogona kuongorora nzira dzakasiyana dzekupa mweya weokisijeni, senge pa-saiti yekugadzira okisijeni zvidyarwa kana zvibvumirano zvenguva refu nevashambadziri vanovimbika, kuita kuti iyo oxygen - yakapfuma leaching process iwedzere kudhura - inoshanda.

mhedziso

Iyo yese - slime cyanidation okisijeni - yakapfuma leaching maitiro inopa mabhenefiti akakosha muindasitiri yekuchera goridhe. Nekuwedzera kukurumidza leaching, kuvandudza goridhe kudzoreredza mitengo, kuderedza kushandiswa kwecyanide, uye nekugona kuderedza saizi yemidziyo, maitiro aya ane mukana wekusimudzira pundutso uye kusimba kwemigodhi yegoridhe. Kunyangwe paine zvimhingamupinyi mukuitwa kwayo, nematanho akakodzera ekuchengetedza, kukwidziridzwa kwemidziyo, uye nzira dzekugadzirisa mutengo, migodhi yakawanda ingangozotora tekinoroji iyi yemhando yepamusoro mune ramangwana. Sezvo kudiwa kwegoridhe kuri kuramba kuchikura, nzira dzakasimba dzekuchera dzakaita seokisijeni - hupfumi hwekucheka huchaita basa rakakosha mukuzadzisa ichi chinodikanwa uku ichideredza kukanganisa kwezvakatipoteredza nehupfumi.
