Ko te tukanga cyanidation he tūāpapa mō te tango koura mai i ōna konganuku. He mea nui te mārama ki te whakamahinga o te konutai cyanide i roto i tēnei tukanga hei whakapai ake i te whai huatanga o te mahi me te whakaiti i te pānga ki te taiao. Ka rukuhia e tēnei tuhinga ngā momo tikanga e whai wāhi ana ki te whakamahinga o te Konutai Cyanide i roto i te tukanga cyanidation koura.
1. Whakawhanake-aunoa
Ka pirau-ā-roto te konutai cyanide i te tukanga cyanidation. Ka hua ake tēnei i te hanganga o te waikawa waro, te waikawa formic, me te haukini. Ka uaua pea ngā tauhohenga pirau-ā-roto, ā, ka pāngia e ngā āhuatanga pēnei i te pāmahana, te kukū, me te aroaro o ētahi whakakorikori.
2. Waiwai
Ko te waikura o te konutai cyanide tētahi atu ara nui o te kai. Ko te tauhohenga i waenga i te wai me te konutai cyanide e whai ake nei:
( H2O + NaCN HCN + NaOH )
Ka puta te hauwai cyanide (HCN), he matū tino pūngāwerewere, he paitini hoki, i roto i tēnei waikura. He hononga tata te nui o te HCN e puta ana ki te kawakore o te wairewa. Ina mau tonu te uara pH ki te 12, neke atu rānei, ka noho pumau tonu te waikura cyanide. Heoi anō, ko ngā matū ka taea te whakaheke i te uara pH, pērā i te hauhā waro mai i te hau, ngā waikawa i roto i te wai hanga, ngā katote konupora takirua ( Mg2+ ) me ngā katote konumohe takirua ( A13+ ), me ngā kohuke rerekē i roto i te konganuku, ngā hua waikura rānei o ngā kohuke whanariki , ka taea te whakatere i te tauhohenga waikura.
3. Te hanga Tiocyanate
Ka tauhohe te konutai cyanide ki ngā kohuke sulfide pērā i te rino, te parahi, me te arsenic hei hanga i ngā matatini thiocyanate. Ka hurihia e ēnei tauhohenga ngā katote cyanide hei momo iti ake te tauhohe, ka whakaitihia te nui o te cyanide kore utu e wātea ana mō te tango koura . Ko te hanganga o ēnei matatini thiocyanate ehara i te mea ka whakanui ake i te whakamahinga cyanide anake engari ka pā hoki ki te whai huatanga whānui o te tukanga cyanidation koura.
Ma te maarama ki enei tikanga kohi ka nui nga maaramatanga mo nga kaiwhakahaere o te umanga keri koura. Ma te aro turuki me te whakahaere i nga tikanga o te mahi cyanidation, ka taea te whakaiti i te kohi cyanide, te whakapai ake i nga reiti whakaora koura, me te whakaiti i te tapuwae taiao o nga mahi keri koura.
