Goridhe Pool Leaching Method: Inoshanda Scope uye process Flow

The goridhe dziva leaching nzira inozivikanwa nekureruka kwayo mukushanda, yakaderera midziyo yekudyara, uye mutengo - kushanda zvakanaka, zvichiita kuti kukurumidza kugadzirwa kwekutanga. Zvisinei, nzira iyi inoda nzvimbo yakakura zvikuru sezvo madziva akawanda ari kudiwa kuti apedze basa reLeaching. Uyezve, haina kukodzera kumarudzi ose egoridhe ores. Ichi chinyorwa chichasuma chiyero chinoshanda, process flow yedziva regoridhe leaching nzira, pamwe chete nekesi inoshanda yekushandisa.

Inoshanda Chikamu cheGoridhe Pool Leaching Method

Ores yegoridhe inokodzera dziva leaching nzira inofanirwa kusangana nematatu maitiro panguva imwe chete. Kutanga, zvimedu zvegoridhe zvinofanirwa kunge zvine saizi yakanaka yekuparadzira. Chechipiri, ore inofanira kunge iri yepasi-giredhi kana yekupedzisira-yakaderera-giredhi. Chechitatu, ore pachayo inofanira kunge isina kupinza zvakanaka. Semuyenzaniso, iron oxide cap - type ores ine yakanaka - grained gold uye oxidized quartz vein ores ine yakatsetseka - yegoridhe yakanyatsokodzera nzira yekudziva leaching.

The Beneficiation kupora mwero yedziva leaching nzira inogona kusvika 70 - 90%. Zvichienzaniswa neCIL neCIP nzira dzekuchera goridhe, nzira yekudziva yekubvisa goridhe ine mutengo wakaderera, zvichiita kuti ive mhinduro inoshanda yekuvandudza kugona kwehupfumi hwegiredhi regoridhe ores. Uyezve, kushanda kwayo kwakapfava kunotungamirira kukuderedzwa kwemari yebasa. Zvakangodaro, nzira yekudziva yekuvharisa inounza mutengo wepamusoro wekuvaka uye inoda nguva yakareba yekudonha. Izvi zvinodaro nekuti zvinodikanwa kuvaka madziva ekuregedza uye madziva emvura asingabereki, kuve nechokwadi kuti ari kuvuza - humbowo uye hwakaoma. Mushure mezvo, ore inoiswa mudziva reLeaching, uye mhinduro yekudonha inogadzirirwa mudziva remvura isina mvura isati yapushwa mudziva rekuleaching. Mushure meimwe nguva, mushonga wepamuviri unoburitswa kuti uendeswe.

Maitiro Kuyerera kweGoridhe Pool Leaching Method

Goridhe dziva leaching rinowanzoitika mumatangi ekutsvaira. Matangi aya anogona kugadzirwa nematanda, zvimwiro zvesimbi, kana simende. Iyo tangi yepasi inogona kunge yakati sandara kana kuti yakarerekera zvishoma, uye inogona kuita denderedzwa, rectangular, kana sikweya muchimiro. Mukati metangi, pasi renhema rakagadzirwa ne perforated acid - mahwendefa anopikisa anoiswa. Mucheka wefirita wakaiswa pazasi penhema, uye girasi rakagadzirwa nematanda kana corrosion - risingachinji simbi mitsetse inoiswa pamusoro pemucheka wesefa. Munguva yekuchenesa, ore inotakurwa mutangi, uye iyo leaching agent inowedzerwa kubva kumusoro. Iyo leaching solution inoyerera kubva pasi pepasi penhema. Pasi penhema rinoshandisa kusefa uye kutsigira ore.

Iyo dziva leaching process inoyerera seinotevera: Iyo goridhe-inotakura ore yakapwanyika kune chaiyo particle saizi inoiswa mutangi rekuleaching. Alkaline cyanide Mushonga unowedzerwa kuti unyikwe, panguva iyo goridhe rinonyungudutswa mumushonga. Mushure mekunyikwa kwenguva yakati, kana huwandu hwemvura hwasangana nezvinodiwa sezvakaonekwa, mushonga une goridhe (mushonga une pamuviri) unoburitswa pasi petangi. Goridhe rinotorwa kuburikidza nekubviswa ne zinc flakes (hupfu) (inoshanda). kabhoni Kunyungudutsa kunogona kushandiswawo). Zvisara zvekubvisa tsvina zvinobviswa mushonga wekubvisa tsvina zvisati zvaraswa. Kuti kubviswe cyanide kubva muzvisara zvekubvisa tsvina, zvinhu zvakaita sesodium bisulfite necopper sulfate zvinogona kuwedzerwa.

Izvo zvinofanirwa kucherechedzwa kuti nguva inodiwa ye percolation tank leaching inotsamira kwete chete pakunyungudika kweyero yekunyungudutsa pamaminerari asiwo pachiyero chekupinda kweiyo solvent kuburikidza neyakagadzirwa layer. Mwero wekupinda unonyanya kuenderana nezvinhu zvakaita sehurefu hwechinhu chakaremerwa, porosity yechinhu, dhigirii resilt yemukati, viscosity yeleaching agent, uye hunhu hwechigadzirwa chacho.
