Kushandiswa kweSodium Cyanide Replacement Technologies muMigodhi midiki

ziviso

Muindasitiri yezvicherwa, kunyanya ye Small Mines, kucherwa kwesimbi dzinokosha segoridhe nesirivha kwagara kuchitsamira pazviri Sodium Cyanide. Zvisinei, kushandiswa kwe sodium cyanide inouya nezvakakosha zvezvakatipoteredza uye kuchengeteka. Iyo ine muchetura zvakanyanya uye inogona kukonzera kusvibiswa kwakanyanya kumatsime emvura uye kukuvadza kuhupenyu hwemumvura. Nekuwedzera kukoshesa kuchengetedza kwezvakatipoteredza uye mitemo yakasimba pasi rose, zvimbambaira zvidiki zviri pasi pekumanikidzwa kukuru kutsvaga dzimwe nzira dzekuchera simbi. Ichi chinyorwa chinoongorora mashandisirwo e Sodium cyanideReplacement Technologiess mumigodhi midiki, nechinangwa chekupa kunzwisisa kwakadzama kwemhinduro dzakasimba idzi.

Zvakaipa zveSodium Cyanide muMigodhi midiki

Njodzi dzezvakatipoteredza

Migodhi midiki inowanzoshaya nzira dzepamusoro dzekugadzirisa marara. Apo sodium cyanide inoshandiswa, kune njodzi yakakura yekudonha kwecyanide mumiviri yemvura iri pedyo panguva yekubvisa. Kunyangwe huwandu hushoma hwecyanide hunogona kukuvadza zvakanyanya kune ecosystem. Semuenzaniso, zvinogona kukonzera kufa kwehove nezvimwe zvipenyu zvemumvura, zvichikanganisa chikafu chose chemumvura. Mukuwedzera, cyanide inogona kuramba iri munharaunda kwenguva yakareba, ichikonzera kukuvadzwa kwenguva refu kwevhu uye mvura.

Njodzi Dziviriro

Kubata sodium cyanide kunoda matanho akasimba ekuchengetedza. Migodhi midiki inogona kusagara iine zviwanikwa zvekuisa mari mumidziyo yakakodzera yekuchengetedza uye kudzidziswa kwevashandi vavo. Kusangana netsaona kune sodium cyanide kunogona kukonzera matambudziko akakomba ehutano kuvacheri, kusanganisira kutadza kufema uye kunyange kufa. Uyezve, kana pakaitika njodzi dzinongoitika dzoga kana tsaona, kuchengetwa uye kutakura kwe sodium cyanide mumigodhi midiki kunogona kuunza njodzi huru kunharaunda dzakapoteredza.

Alternative Technologies kune Sodium Cyanide

Thiosulfate Leaching

Thiosulfate leaching isiri-chepfu imwe nzira kune cyanide - based extraction. Inoshandisa thiosulfate ions kunyungudutsa goridhe kubva mu ores. Iyi nzira ine hushamwari hwezvakatipoteredza sezvo isingabudisi zvinhu zvine chepfu zvakanyanya. Mumigodhi midiki, thiosulfate leaching inogona kuve sarudzo yakakodzera sezvo inogona kuiswa kune akasiyana marudzi e ore. Zvisinei, ine mamwe matambudziko. Zvinogona kuda yekuwedzera maitiro optimization, sekudzora pH uye tembiricha yemhinduro yeleaching zvakanyanya. Zvakare, mari yekushanda yakakwira zvakanyanya kana ichienzaniswa necyanide leaching, zvakanyanya nekuda kwemutengo wetiosulfate reagents uye kudiwa kwemidziyo yakaoma mune dzimwe nguva.

Chloride Leaching

Chloride leaching inosanganisira kushandisa chloride ion kunyungudutsa goridhe nemamwe masimbi kubva mu ores. Inopa njodzi dzakaderera dzezvakatipoteredza zvichienzaniswa necyanide. Migodhi midiki inogona kubatsirwa nenzira iyi sezvo ichikwanisa kuenderana nemamiriro enzvimbo. Semuenzaniso, munzvimbo dzinowanikwa chloride-ine zvinhu zviri nyore, mutengo wemaagents unogona kudzikiswa. Nekudaro, kubata ne-zvigadzirwa uye marara kubva kune chloride leaching inogona kuve yakaoma. Chloride - marara akapfuma angada kurapwa kwakakosha kudzivirira kuora kwemidziyo uye kusvibiswa kwezvakatipoteredza.

Bioleaching

Bioleaching inoshandisa microbial chiitiko kubvisa simbi kubva ores. Iyi ndiyo yakagadzikana uye eco-hushamwari imwe nzira. Zvipembenene, zvakadai sehumwe utachiona, zvinogona kupaza simbi yacho ndokubudisa simbi dzacho. Kune migodhi midiki, bioleaching ine mukana wekuve nyore kumisikidza mune zvimwe zviitiko. Hazvidi midziyo yakanyanyisa. Nekudaro, kugona kwebioleaching kunogona kudzikiswa nezvinhu zvakaita serudzi rweore uye basa rema microorganisms. Mamwe maore anogona kusaora nyore nyore neanowanikwa tupukanana, uye kukura uye kuita kwema microorganisms kunogona kukanganiswa nemamiriro ekunze senge tembiricha uye pH.

Kushandiswa Kwenzvimbo - hushamwari Gold Dressing Agents

There are several environment - friendly gold dressing agents available in the market that can replace sodium cyanide. For example, the "Jinchán" environmental - friendly gold dressing agent developed by Guangxi Senhe High - tech Co., Ltd. has the advantages of low toxicity, high recovery rate, and easy operation. These agents can be used in the same processes as sodium cyanide, such as heap leaching, pool leaching, and kabhoni - in - pulp processes. They can effectively extract gold from various types of ores, including those with complex compositions. Another example is the CNFREE sodium cyanide substitute, which can be directly used for gold ore dressing and refining without changing the original equipment and cyaniding process, truly achieving the goal of green environmental protection.

Matambudziko uye Mhinduro muKushandisa Alternative Technologies muMigodhi Midiki

Mutengo - kubudirira

Rimwe rematambudziko makuru emigodhi midiki pakutora mamwe matekinoroji mutengo - kushanda zvakanaka. Dzakawanda dzimwe nzira, senge thiosulfate leaching, inogona kunge iine yakakwira yekutanga mari yekudyara yemidziyo uye reagents. Kugadzirisa izvi, zvimbambaira zvidiki zvinogona kufunga kushandirapamwe nemasangano ekutsvagisa kana makambani makuru emigodhi kuti vagovane mutengo wekutsvaga nekugadzira nzira dzinodhura - dzinoshanda. Pamusoro pezvo, rubatsiro rwehurumende kana kurudziro zvinogona kupihwa kukurudzira zvimbambaira kuti zvishandise matekinoroji aya.

Unyanzvi hwehunyanzvi

Migodhi midiki inogona kushaya hunyanzvi hwehunyanzvi hunodiwa kuti ushande nekugadzirisa mamwe matekinoroji aya. Zvirongwa zvekudzidzisa zvinogona kurongwa nemasangano emaindasitiri kana masangano ehurumende kuti vadzidzise vashandi vemumigodhi mashandisirwo akanaka enzira itsva dzekuchera. Semuenzaniso, kudzidziswa nezve maitiro ekudzora ma paramita mu thiosulfate leaching kana maitiro ekugadzirisa hutachiona nharaunda mu bioleaching. Uyezve, vanopa tekinoroji vanogona kupa - saiti tekinoroji rutsigiro kumigodhi midiki panguva dzekutanga nhanho dzekutora matekinoroji matsva.

Regulatory Adaptation

Mamiriro ekugadzirisa zvicherwa ari kuramba achichinja. Migodhi midiki inofanirwa kuona kuti mamwe matekinoroji avanotambira anoenderana nemitemo yemuno neyekunze. Izvi zvinoda kurukurirano yepedyo nevane masimba. Masangano anodzora anogonawo kuita basa nekupa nhungamiro dzakajeka pamusoro pematanho anogamuchirika ekukanganisa kwezvakatipoteredza uye mwero wekuchengetedza kune mamwe matekinoroji, zvichiita kuti zvive nyore kumigodhi midiki kugadzirisana.

mhedziso

Kushandiswa kwesodium cyanide kutsiva tekinoroji mumigodhi midiki kwakakosha mubudiriro inoenderera muindasitiri yezvicherwa. Kunyangwe paine zvimhingamipinyi zvakaita semutengo - kushanda zvakanaka, hunyanzvi hwehunyanzvi, uye kuchinjika kwemitemo, mabhenefiti eaya mamwe matekinoroji maererano nekuchengetedza kwezvakatipoteredza nekuchengetedza akakosha. Nekugadzirisa zvimhingamipinyi izvi kuburikidza nekushandira pamwe, kudzidziswa, uye kutaurirana zviri nani nevane masimba, zvimbambaira zvidiki zvinokwanisa kuchinjika kuenda kukushandisa nzira dzakasimba dzekuchera, kuve nechokwadi chekushanda kwenguva refu kwekushanda kwavo uku ichideredza kukanganisa kwayo kune zvakatipoteredza uye nzanga.
