Pūrongo Rangahau Ahumahi 2026 mō te Waro Whakahohe Anga Kokonati mō te Whakaora Koura

1. Tirohanga Whānui mō te Ahumahi i te tau 2026

Tae noa ki te tau 2026, ko te waro whakahohe anga kokonati tonu te rauemi mimiti e whakamahia whānuitia ana i roto i ngā tukanga whakaora koura o te ao, inā koa i roto i ngā pūnaha CIP, CIL, CIC, me te puranga . Ahakoa te putanga mai o ngā puna waro rerekē me ngā mea mimiti hangai, kei te kaha tonu ngā waro whakahohe anga hua ki ngā tono keri koura nā te pumau o te hanganga, te pai o te mimiti, me te mahi ahumahi kua whakamātauhia.

I roto i ngā waro anga hua, ko te waro whakahohe o te anga kokonati te paerewa ahumahi, ko te anga aperikota, te anga pītiti, me ētahi atu waro anga hua ka whakamahia i roto i ngā horopaki iti, motuhake rānei, i runga i ngā āhuatanga o te konganuku me ngā tikanga whakahaere.

2. Te Tūranga o te Waro Whakahohe i roto i ngā Tukanga Whakaora Koura

I roto i ngā pūnaha tātā cyanide , ka whakamahia te waro whakahohe hei mimiti i te koura rewa i te āhua o te matatini dicyanoaurate Au(CN)₂⁻ mai i ngā wai tātā, i te penupenu rānei.

Ka pā tika te mahi a te waro whakahohe ki:

• Te tere mimiti koura

• Te kukū koura toenga i roto i ngā paru

• Te kaha uta waro

• Te whai huatanga o te elution me ngā huringa whakaora waro

Mā te waro whakahohe kounga teitei ka tere ake te mimiti, ka iti ake ngā ngaronga koura, ka roa ake te ora o te whakamahinga , ka waiho hei mea tino nui hei whakapaunga, kaua hei rauemi āwhina noa iho.

3. Ngā Momo Matua o te Waro Whakahohe Anga Hua e Whakamahia ana i te Keri Koura

3.1 Waro Whakahohe Anga Kokonati

I hangaia mai i ngā anga kokonati mā te whakawaro me te whakahohe i te pāmahana teitei, ko ngā āhuatanga o te waro o te anga kokonati:

• He hanganga moroiti tino whanake

• Te kaha miihini

• He ātete pai ki te pakaru

• Te whanonga mimiti pumau mō ngā huringa maha

Koinei te kōwhiringa pai mō ngā mahi kohikohi koura nui, tonu.

3.2 Waro Whakahohe Anga Āperekoti

Ko ngā āhuatanga o te anga aperikota e whakaatu ana i te nuinga o te wā:

• Te whanaketanga o ngā pore ngawari

• He iti ake te pakeke ki te whakaritea ki te waro anga kokonati

• Te mahi mimiti e whakaaetia ana i roto i ngā pūnaha iti-te-pakurakura

Ka whakamahia i ētahi wā i roto i ngā mahi iti, i ngā mahi tairongo rānei , engari me āta whakahaere i ngā āhuatanga whakahaere.

3.3 Waro Whakahohe Anga Pītiti

Ko ngā āhuatanga o te waro anga pītiti ko:

• Te tohatoha rahi o ngā pore kāore i te ōrite

• He iti ake te kaha miihini

• Te nui ake o te hiahia ki te whakaputa i ngā whiu waro

He iti noa iho tōna whakamahinga i roto i te whakaora koura, ā, he iti noa iho te matotoru o te penupenu e whakamahia ana.

3.4 Ētahi atu Waro Whakahohe Anga Hua

Kei roto i tēnei kāwai ngā waro whakahohe i ahu mai i:

• Anga waanati

• Ngā anga nikau

• Ngā hua taha ahuwhenua whakaranu

Ka rerekē rawa te mahi a ēnei rauemi i runga i te kounga o ngā rauemi mata me te tukanga whakahohenga, ā, kāore i te tino paerewa mō ngā mahi keri koura.

4. Whakataurite Paerewa Hua mō te Waro Whakahohe Whakaora Koura

4.1 Ngā Tohu Mahi Matua (Ngā Awhe Ahumahi Noa)

👉 I te tau 2026, ka whakatairangahia e ngā mahi whakaora koura tino whai hua te taurite mahi whānui, kaua ki tētahi tawhā kotahi pēnei i te tau iodine.

5. Te Whakamārama i te Whai Huatanga o te Whakaora Koura

5.1 Te Mahi Whakamomona

E whakaatu tonu ana te waro whakahohe anga kokonati i:

• Te utaina taurite teitei ake

• He pai ake te whiriwhiri mō ngā matatini koura

Ahakoa te pai o te mahi a ngā waro anga hua rerekē i raro i ngā āhuatanga whakahaeretia, he maha ngā wā ka nui ake te aro ki te matū o te penupenu me te ahotea ā-pūkaha.

5.2 Pānga ki te Mahi Whānui o te Whare

Ka pā te whiriwhiringa o te waro whakahohe ki:

• Te hurihanga o ngā rawa waro

• Auautanga o te whakakapinga waro

• Ngā ngaronga koura i roto i ngā paru

• Te pumau o ngā ara iahiko elution me te electrowinning

I roto i ngā konganuku koura iti te kounga, ahakoa he iti noa te whakaiti i te pai o te mimiti ka pā nui ki te ōhanga o te kaupapa.

6. Waro Anga Kokonati me ētahi atu Waro Whakahohe Anga Hua (Whakarāpopototanga)

7. Ngā Auahatanga Ahumahi me ngā Whakaaro Hoko i te Tau 2026

Nga Ahumahi Ahumahi

• Te whakanui ake i te aro ki ngā utu whakahaere mō te wā roa, kaua ki te utu mō ia wae
