Te Whakataurite i waenga i te Konutai Cyanide me ngā Kaihoko Whakarewa Taiao i te tau 2026

1. Te Papamuri o te Ahumahi i te tau 2026

Ko te hangarau tango koura i te tau 2026 kei te huarahi whakawhiti i waenga i te pakeketanga o te ahumahi a te whakawhiti taiao. konutai tina (NaCN) tonu te mea e whakamahia whānuitia ana Kaiwhakaora Horoi Koura puta noa i te ao nā te mea he tino pai te hangarau me ngā painga ōhanga. I taua wā anō, kei te aro tonu ngā kaihoko horoi wai e pai ana ki te taiao, e hokohokohia ana he "kāore he cyanide" he "kaituku wai matomato rānei," i raro i ngā ture taiao e piki haere ana me ngā anga haumi e whakahaerehia ana e te ESG.

Engari i te whanaungatanga whakakapinga noa iho, e whakaatu ana te ao o nāianei i te te noho tahi me te wehewehe i waenganui i konutai Cyanide me ngā pūnaha tātā rerekē, ia pūnaha e whakatutuki ana i ngā momo konganuku rerekē, ngā taiao ture, me ngā whāinga whakahaere rerekē.

2. Ngā Mātāpono Matū me te Hangarau

2.1 Te Tikanga Whakarewa o te Konutai Cyanide

Ka whakarewahia te koura e te konutai cyanide mā te tauhohenga Elsner kua roa e whakamahia ana:

4Au + 8NaCN + O₂ + 2H₂O → 4Na[Au(CN)₂] + 4NaOH

Ngā āhuatanga hangarau matua:

• He tino whiriwhiri mō te koura me te hiriwa

• Kua whakamātauhia te hototahitanga ki te CIP/CIL me ngā pūnaha tango puranga

• Ngā nekehanga ka taea te matapae me te whakahaere tukanga pumau

• He nui ngā raraunga ahumahi i kohia mō ngā tau neke atu i te 130

2.2 Ngā Tikanga Whakarewa Taiao

Ko ngā kaihoroi e pai ana ki te taiao ko ngā pūnaha e hangai ana ki te thiosulfate, ngā pūnaha e hangai ana ki te glycine, ngā pūnaha chloride, me ngā matū motuhake. He rerekē ā rātou tikanga, engari ko te nuinga o te wā ka whakawhirinaki ki:

• Te whakakotahitanga o te koura i raro i ngā āhuatanga kawakore ngawari, āhua koretake rānei

• He iti ake te paitini whakapeka ki te whakaritea ki te cyanide

• Te matū matū matū me te aro o ngā tukanga he uaua ake

Ahakoa he ātaahua te ariā, he maha tonu ngā pūnaha hoa-taiao kāore i te whai hua ngā tauira ahumahi paerewa puta noa i ngā tinana kōhatu rerekē.

3. Te Whai Hua o te Whakarewa me ngā Reiti Whakaora

I roto i te 2026, konutai cyanide kei te waiho tonu hei paearu mō ngā mahi whakaora-teitei, nui-tauine, inā koa mō ngā konganuku iti te kounga me ngā konganuku ātete i muri i te maimoatanga o mua. He pai te mahi a ngā kaihoko hoa taiao i roto i ngā konganuku waikura kounga teitei, ngā konganuku waikura ngāwari rānei, engari he rerekē rawa te auau o te whakaoranga.

4. Whakataurite Hanganga Utu

4.1 Konutai Cyanide

• He iti te utu mō ia tana o te konganuku

• Te mekameka tuku taonga o te ao kua pakari

• Ngā reiti kai e matapaetia ana

• Te iti o te CAPEX nā te mea he taputapu paerewa

4.2 Ngā Kaihoko Whakarewa Taiao

• Te utu teitei ake o ngā waeine matū

• He maha ngā wā ka nui ake ngā reiti kai

• Ngā pūnaha whakahaere tāpiri e hiahiatia ana

• Te pikinga ake o te OPEX nā te uaua o te matū

I roto i te maha o ngā mahi arumoni, kei te noho tonu te utu katoa mō te horoi i te wai mā te whakamahi i ngā kaihoko e pai ana ki te taiao. 20–50% teitei ake atu i konutai cyanide ina aromatawaitia i runga i te uara koura mō ia aune.

5. Nga Whakaaro Taiao me te Haumaru

konutai Cyanide

• Te paitini nui

• Ngā whakaritenga mō te whakahaere, te kawe, me te tango paitini tino pakari

• Ngā tukanga whakangaromanga kua whakapumautia (INCO, SO₂/Hau, H₂O₂)

• Ngā anga ture kua whakamātauhia i raro i te International Cyanide Management Code

Ngā Kaihoko Whakarewa Taiao

• Te iti o te paitini whakapeka

• Te whakaiti i te tirohanga mōrearea a te marea

• Me tango tonu te paitini mō ētahi hua taha

• Ka whakawhirinaki te pānga ki te taiao ki te momo matū me te whanonga pirau

Ko te mea nui, kounga whakahaere mōrearea, ehara i te kōwhiringa matū anake e whakatau ana i te mahi tūturu a te taiao.

6. Te Whakaaetanga Ture me ngā Auahatanga ESG

E 2026:

• Kei te whakaaetia tonutia te konutai cyanide i roto i te nuinga o ngā mana whakahaere keri i raro i ngā tikanga whakahaere.

• He iti noa ngā rohe e aukati ana i ētahi wā (hei tauira, ētahi whenua o te EU)

• Ka akiaki te pēhanga ESG i ngā whakamātautau o ngā matū rerekē, inā koa mō ngā kaupapa hou

Heoi anō, ko te nuinga o ngā maina nui kei te whakawhirinaki tonu ki te konutai cyanide nā te mea te māramatanga ture, te inihua, me te āheinga ki te peeke.

7. Ngā horopaki tono i te tau 2026

He pai ake te whakamahi i te konutai cyanide ina:

• Te tukatuka i ngā kohatu nui, ngā kohatu iti te kounga

• E hiahiatia ana te whakaoranga teitei me te putanga pumau

• Kei te wātea ngā hanganga CIP/CIL o nāianei

• He mea nui te whai huatanga o te utu

He pai ngā Kaihoroi Horoi Taiao ina:

• He ture te aukati i te whakamahinga o te cyanide

• Ka whakahaerehia ngā mahi iti, ngā mahi whakamātautau rānei

• He nui te pēhanga mō ngā raihana tūmatanui, ā-pāpori rānei

• Ko ngā āhuatanga o te konganuku e pai ake ana ki te matū rerekē

8. Tirohanga a meake nei

I te tau 2026, ka whakamahia ngā kaihoroi wai e pai ana ki te taiao ehara i te whakakapinga whānui mō te konutai cyanide engari hei mahi tāpiringa rautaki i roto i ngā āhuatanga motuhake. Ko te konutai cyanide tonu te paerewa ahumahi mō te tango koura, ko ngā matū matū matomato kei te whanake tonu mā te tono kua whakaritea, te whakapainga hangarau, me te whakaurunga tukanga ranu.

Ko te heke mai o te tango koura ehara i te mea kei te whiriwhiri i ngā taha, engari kei roto i te arotautanga tukanga, te whakahaere mōrearea, me te kōwhiringa matū motuhake ki te konganuku.

9. Whakamutunga

E rua ngā ara ōrite o te mahi whakarewa koura hou, arā, te konutai cyanide me ngā kaihoroi pai-taiao. He tino pai te whai huatanga, te kaha ki te whakawhanui, me te pumau ohaoha o te konutai cyanide, ā, ko ngā kaihoroi pai-taiao e aro ana ki ngā whakaaro ture, pāpori, me te taiao i roto i ngā tono motuhake.

I te tau 2026, kāore ngā kaiwhakahaere whai mōhio e pātai "Ko tēhea matū te mea pai ake?"
Ka patai ratou "Ko tēhea matū matū te mea tika mō tēnei konganuku, mō tēnei rohe, me tēnei kaupapa?"
