Iyo Impact yeSustainability mukati meMigodhi Indasitiri

COP26, net-zero tarisiro, uye kukurumidza kusimuka kuenda kune kuchengetedzwa kwakanyanya zvine zvazvinoreva zvakanyanya kuindasitiri yezvicherwa. Munhevedzano yeQ&As, tinokurukura matambudziko akabatana nemikana. Tinotanga nekunyatsotarisisa mamiriro aripo eindasitiri iyi yakaoma pasi rose, naEllen Thomson, PGNAA & Minerals Senior Applications Nyanzvi kuThermo Fisher Sayenzi.

Isu hatiwanzoona zvinangwa zvine chekuita nekucherwa, kupfuura chinangwa chakagovaniswa chenet-zero. Pane here zvisungo kubva kuCOP26 zvinokanganisa vashandi vemumigodhi?

Ndinofunga kuti zvakanaka kutaura kuti, kazhinji, pane nzwisiso yekuti zvakakosha sei kucherwa kwezvicherwa kukuedza kwedu kwakabatana kune imwe nyika yakasimba, yakachena.

Tora zvisungo zveCOP26 zvakatenderedza zvifambiso - iyo 2040 yekucheka-kubviswa kwese kutengeswa kwemotokari kutsva kuve zero-emissions (2035 yemisika inotungamira)1. Kuzadzikisa zvinangwa izvi kunotsamira pakuwedzera zvakanyanya zvinhu zvecobalt, lithium, nickel, aluminium, uye, kunyanya, mhangura. Kudzokorodza hakuzadzise kudiwa uku ‒ kunyangwe kunyatsoshanda patsva kwakakosha ‒ saka tinoda kutora mamwe masimbi kubva pasi. Uye inyaya imwe chete ine simba rinodzokororwa, iro rakapetwa kashanu mhangura-yakawanda kupfuura yakajairika dzimwe nzira2.

Saka hongu, vashandi vemumigodhi vanotarisana nematambudziko akafanana nemamwe maindasitiri maererano nekurova mambure-zero zvinangwa, kuderedza kukanganisa kwezvakatipoteredza, nekuvandudza kusimba, asi maererano nemamiriro ezvinhu ezvigadzirwa zvavo zvakakosha pakuzadzikiswa kwezvimwe zvinangwa zvekuchengetedza.

Zvingave nyore sei kuunganidza zvigadzirwa zvesimbi kuti zvizadzise kudiwa kuri kukura?

Tiri kutaura pamusoro pekuwedzera kukuru uye kwakasimba, saka hazvizove nyore. Nemhangura, semuenzaniso, pane fungidziro yekushomeka kwematani miriyoni gumi nemashanu pagore panosvika 2034, zvichibva pazviri kubuda mugodhi3. Migodhi yekare inoda kushandiswa zvizere, uye madhipoziti matsva akawanikwa nekuunzwa.

Chero nzira, izvi zvinoreva kugadzirisa yakaderera-giredhi ore zvakanyanya. Mazuva ekucherwa kwesimbi ane 2 kana 3 % simbi yakasungwa zvakanyanya aenda, sezvo ore iwawo zvave kupera. Vacheri vemhangura pari zvino vari kugara vakatarisana ne0.5% chete. Izvi zvinoreva kugadzirisa dombo rakawanda kuti uwane chigadzirwa chinodiwa.

Vashandi vemumigodhi vakatarisanawo nekuongororwa kuri kukura maererano nerezinesi rekuita basa revanhu. Pane kushivirira kushoma kwekudzika kwemugodhi - kusvibiswa kana kupera kwemvura, kusatarisika uye kunogona kukuvadza kukanganisa kwemisara, uye kukanganisa kune magetsi. Sosaiti pasina mubvunzo iri kutarisa kune indasitiri yezvicherwa kuti ibudise simbi dzinodiwa asi mukati menzvimbo yakamanikidzwa kushanda. Nechinyakare, migodhi yave ine nzara yesimba, mvura-yakawanda uye ine tsvina indasitiri, ine yakakura tsoka yezvakatipoteredza. Makambani akanakisa ave kugadzira zvinhu padanho rekuvandudza pamativi ese.

Ndedzipi nzira dzaunofunga kuti dzichanyanya kukosha kuvacheri kana tasvika pakugadzirisa matambudziko avanosangana nawo?

Kunyange pasina kupokana kuti vashandi vemumigodhi vanosangana nematambudziko akakura, mamwe maonero ndeokuti mamiriro azvino anopa mikana yakasarudzika yekuchinja. Nekuda kwakachengeteka, pane kukurudzira kukuru kwekuvandudza, saka hazvina kumbobvira zvave nyore kupembedza kukwidziridzwa kune nzira dziri nani dzekushanda. Smarter tekinoroji pasina mubvunzo ndiyo nzira yekumberi, uye pane chido nazvo.

Yakakodzera, yakavimbikale ruzivo rwedhijitari ndiro ibwe repakona rekushanda kwakanaka uye kazhinji kunoshaikwa. Ini saka ndinosimbisa mari mukuongorora kunoshanda uye kuenderera senzira yakakosha yekubudirira. Ne data-chaiyo-nguva, vacheri vanogona a) kuvaka kunzwisisa kwakasimba kwemaitiro maitiro uye b) kumisikidza yepamusoro, otomatiki maitiro ekudzora, kutyaira kuenderera mberi nekuvandudza kuburikidza nemichina yekudzidza matekiniki. Iyi ndiyo imwe yenzira huru dzatichasandura kuita maoperation anoburitsa yakawanda ‒ kuburitsa simbi yakawanda kubva kune yega toni yedombo ‒ inoderedza simba, mvura, uye makemikari ekuisa.

Ndeapi mazano aungapa vashandi vemumigodhi pavanotanga hurongwa hwekutsvaga matekinoroji nemakambani anogona kuvabatsira?

Ndingati nditsvage makambani anoratidza kunzwisisa kwakadzama kwenyaya dzako uye kuti matekinoroji avo anogona kubatsira sei. Tsvaga zvigadzirwa zvine rekodhi yakasimbiswa, yakaputirwa nehunyanzvi. Zvakare, tsvaga vatambi vechikwata. Kuvandudza kushanda kwemugodhi kunotora ecosystem yevanopa tekinoroji. Vatengesi vanofanirwa kunzwisisa zvavanogona kupa, uye maitiro ekubatanidza zvinobudirira nevamwe. Zvakakoshawo kuti vagovane zvaunokoshesa. Iyo Sainzi Yakavakirwa Targets chirongwa (SBTi) inzvimbo yakanaka yekutanga kana iwe uchitsvaga makambani ari kuseta dzimba dzawo kuitira kuenderera mberi, nekushandisa zviyero zvinoyerwa uye zvinoda.

Zvigadzirwa zvedu zvemigodhi zvese nezve sampling uye kuyerwa. Isu tinopa samplers, muchinjika-bhandi uye slurry analyzer, uye bhandi zvikero zvinopa elemental kuyerwa uye traceability munguva chaiyo-nguva. Mhinduro idzi dzinoshanda pamwe chete, semuenzaniso, kupa ruzivo rwunodiwa pakuisa matombo kana kurongedza. Kuronga simbi kunobvumira vashandi vemigodhi kusanganisa ore iri kuuya zvinobudirira, kushandisa feed forward process control, uye nzira yakaderera kana magiredhi yegiredhi zvinhu kure neconcentrator nekukurumidza. Real-time elemental ongororo yakangokoshawo kuburikidza neconcentrator yemetallurgical accounting, process control kana kuteedzera tsvina yekunetseka.

Nezviyereso zvenguva chaiyo, zvinogoneka kugadzira mapatya edhijitari yekushanda kwemigodhi - pfungwa yatiri kuuya nayo nekuwedzera frequency. Mapatya edhijitari idhijitari yakakwana, yakaringana vhezheni yeconcentrator. Kana uchinge uine imwe, unogona kuyedza nekugadzirisa, uye pakupedzisira, kudzora kure chinhu kubva padesktop yako. Uye pamwe iyo ipfungwa yakanaka yekukusiya nayo sezvo otomatiki, migodhi isina vanhu ndiyo chiono cheramangwana. Kutsvaga vanhu kumigodhi kunodhura, uye nehunyanzvi, hwakavimbika tekinoroji inotsigirwa nekugadzirisa kure, hazvizongove zvakakosha mumakumi emakore ari kuuya.
