Nzira shanu dzeKunatsurudza Mhedzisiro yeGoridhe Ore Murwi Wekudzidzisa

Kubvisa goridhe kubva mumatombo emuhombe kunosanganisira maitiro maviri: kubvisa goridhe kubva mumafuta emuhombe uye kubvisa goridhe kubva mumafuta emuhombe. Hunhu hwekubvisa goridhe kubva muhombe hunokanganisa zvakananga kubudirira kwekubvisa goridhe kubva muhombe. Izvi zvinonyanya kuunza zvinhu zvishanu pamusoro pekuti ungawedzera sei simba rekubvisa goridhe kuburikidza nekubvisa goridhe kubva muhombe.

1. Kushandiswa kweGranulation Technology

Munguva yekunyudzwa kwegoridhe ore, ores ane ivhu rakawanda kana kuti akatsetseka - zviyo hazvina kukodzera kudonhedza murwi wakananga uye zvinoda granulation pretreatment kuvandudza kupenya kwemhepo yemurwi weore. Granulation pretreatment inogona kuwedzera iyo leaching rate yegoridhe uye, kazhinji, zvakanyanya kuwedzera goridhe leaching rate. Zvichienderana nemamiriro ezvinhu, ore inogona kuve yakazara granulated, kana chete yakanaka - gorosi kana chikamu granulation inogona kuitwa.

Semuyenzaniso, muna 1991. mumwe mugodhi wegoridhe mu Xinjiang, China, akaita yakakura - chiyero (24.000 matani) granulation murwi leaching kekutanga. Nguva yeLeaching yakapfupikiswa nemazuva makumi matatu nemashanu kana zvichienzaniswa neakananga murwi leaching, uye chiyero cheleaching chakawedzera kubva pa35% kusvika 49.69%.

2. Kuvandudza Permeability yeOre Murwi uye Solution

Piling chikamu chakakosha chegoridhe ore murwi leaching process. Murwi wese weore unofanirwa kuve nekupenya kwakafanana kudzivirira nzira kana kuvharika kwenzvimbo. Naizvozvo, zvinokurudzirwa kushandisa advanced arc - yakaumbwa nyowani ore murwi wekuvaka midziyo uye kutora nzira yekuyerera kwe "segmented stacking, cross-spraying, uye multi-stage counter - current leaching". Zvadaro, jekiserai mweya mumurwi wesimbi uye woisa pombi dzekuunganidza mvura kuti uvandudze kupinza kwemhepo yemurwi wesimbi uye kudonha.

Kazhinji, zvishandiso zvinopinda mukati meokisijeni zvinofanirwa kuiswa panguva yekuputira kuti ivandudze kupinza kwemhepo uye chiyero chekudonha chemurwi.

Semuenzaniso, mumirwi leaching, matanda egakanje, bamboo tubes, nezvimwewo zvinovigwa. Mushure mekudonha kwechinguva, zvinhu zvakavigwa izvi zvinodhonzwa kuti zvivandudze kupera kwegoridhe leaching. Kana, mushure mekudonha kwemurwi kwenguva yakati rebei, kuputika kwakasununguka kwenzvimbo kunoitwa pamvura - zvikamu zvakaunganidzwa, izvo zvinogona zvakare kusunungura murwi weore uye kunatsiridza kupera.

Mhedzisiro yetsvakiridzo kubva kuHazen Research Institute iri muUnited States inoratidza kuti kuwedzera mweya weokisijeni mumurwi weore hakungopfupikidze kutenderera kwechinenge chikamu chimwe chete muzvitatu asiwo kuwedzera mwero wegoridhe.

3. Kuchengeta Tembiricha Yakakodzera yeLeaching

Nzira yecyanidation ine zvinodiwa zvakanyanya zvekushisa. Naizvozvo, mumamiriro ekunze anotonhora, chipingamupinyi chikuru mukututira leaching itembiricha yeleaching. Kana tembiricha yekudonha yakadzikira kupfuura 10 ° C, kunyungudika kwegoridhe kunodonha zvakanyanya. Kuti udambure tembiricha uye kuwedzera mwaka wekudonha kwemurwi, mushonga unofanirwa kupiswa usati wadonha wozotumirwa kumurwi wematombo.

Mimwe migodhi muCanada inoshandisa kupisa kwemarara kupisa mhinduro, zvichiwedzera nguva yekushanda murwi. Mugodhi weGoridhe weRichmond Hill muSouth Dakota, USA, unoshandisa kudiridza kwekudonha uye kupisa - midziyo yekunyudza pamuviri wemurwi kuti iwane kuenderera mberi kwekugadzirwa munguva yechando.

4. Kushandiswa kweDrip Irrigation

Kupfapfaidza kudiridza nekudiridza inzira mbiri dzakasiyana dzekuparadzira mvura mudutu rekuleaching, ese ari maviri anogona kuburitsa yunifomu yekugovera mvura.

Zvisinei, kuwanda kwekunyungudutsa kwemvura mupfapfaidzo hakusi nyore kudzora, chiyero cheleaching hachisi nyore kuwedzera, uye panguva imwe chete, iyo cyanide diki - ine madonhwe emvura akapfapfaidzwa mumhepo zviri nyore kuparadzira uye kusvibisa nharaunda. Kuderedza kushandiswa kwesimba uye kuwedzera chiyero cheleaching, nzira yekudiridza yedrip inogona kutorwa.

Zvakanakira Drip Irrigation

• Drip irrigation inogona kuwedzera mhepo yemukati mumhinduro, kureva, iyo okisijeni yemukati inotora chikamu mukuita kwemakemikari inowedzera, nekudaro ichiwedzera chiitiko chekunaya kwegoridhe.

• Kudiridza nemadonhwe kunogona kudzora kuzara kwecyanide solution uye kuderedza kurasikirwa kweSodium cyanide mumhepo.

• Drip irrigation iri nyore kuwedzera tembiricha yekudzora tembiricha kuti uwane chinangwa chekuwedzera tembiricha yemurwi leaching chemical reaction.

• Drip irrigation ine dhigirii repamusoro re automation, kugadzirwa kwakanyanya, uye mutengo wakaderera wekugadzira.

5. Kushandisa Sefa Aids

Sekuwedzera, iyo leaching aid inowedzerwa kune cyanide - leached pulp. Kune rumwe rutivi, inogona kuwedzera kusangana pakati pecyanide negoridhe; nerumwe rutivi, inogona kubvisa kana kunetesa pesvedzero yezvinhu zvinokuvadza zvetsvina pane cyanide leaching yegoridhe, nekudaro ichiwedzera kuparara uye leaching maitiro eiyo leaching rubatsiro pagoridhe, pakupedzisira ichidzikisa mutengo wekugadzira nekuvandudza mabhenefiti ehupfumi emabhizinesi.

Inowanzo wedzera leaching aids panguva yemurwi leaching process inosanganisira oxidants, inowedzeredzwa leaching agents, wetting agents, nezvimwe.

• Kuwedzera okisijeni - ine oxidants (H₂O₂, CaO₂, Na₂O₂, nezvimwewo) panguva yecyanide leaching process inogona kuwedzera iyo "inoshanda inoshanda okisijeni" mupulp, nekudaro ichivandudza leaching mhedzisiro yegoridhe ore.

• Kuwedzera huwandu hwakakodzera hwekunyorovesa ajenti kana yakakwidziridzwa leaching agent kune cyanide mhinduro inobatsira kupinda kweiyo cyanide mhinduro uye inosimudzira kuita pakati peiyo cyanide mhinduro negoridhe rakavharwa.

6. Mhedziso

Chinyorwa ichi chinonyanya kutaura nezve mirwi yekubvisa migodhi yegoridhe. Iyo murwi leaching process ine hunhu hwezvivakwa zviri nyore, kushanda kuri nyore, uye hupfumi hwenzvimbo yekugara, iyo inogamuchirwa nevazhinji varidzi vemigodhi yegoridhe. Nekudaro, iyo goridhe yekubvisa mhedzisiro yemurwi wekucheka maitiro inokanganiswa nezvakawanda zvinhu. Zvinokurudzirwa kuti varidzi vemigodhi vagadzire hurongwa hune musoro hwekuita murwi kuburikidza nekugadzira chirongwa chesainzi. Edzai uye sarudza yakakodzera murwi leaching midziyo, uye gadziriso dzinogona kuitwa zvinoenderana nemamiriro chaiwo efekitori zvichireva nezvezvishanu zvinotevera:

• Kushandisa tekinoroji yegranulation mune ores ine magiredhi akachekwa-chekwa kana yakakwira ivhu yemukati uye kusapinda kwemhepo.

• Kuvandudza kupinza kwemurwi weore uye mhinduro.

• Kuchengeta tembiricha yakakodzera yekudonha.

• Kushandiswa kwedrip irrigation.

• Kushandiswa kwemafirita aids.

Kana iwe uchifarira murwi leaching maitiro, ndapota siya meseji kuti utaure nesu kana kubvunza yedu yepamhepo vatengi sevhisi, uye isu tichakubata iwe nekukurumidza sezvinobvira.
