Te Whakaterengai roto i te Whakawhiwhinga
Mā te whakapūmau i te uara o ngā konganuku ka whakanuia te uara o ngā konganuku mā te wehewehe i ngā kohuke whai hua mai i ngā kohuke gangue i roto i te tukatuka kohuke mā roto i ngā rerekētanga ā-tinana me te matū. Ahakoa e mahi ana ki ngā konganuku kore-whakarewa, ki ngā konganuku rino, ki ngā kohuke kore-whakarewa rānei, he mea nui te whakapūmau i te kounga teitei o ngā rauemi mata.
1. Ngā Tikanga Whakatere
(1) Te Whakaterenga Tika
Ko te whakapūmau tika e pā ana ki te tātari i ngā kohuke whai hua mai i te paru mā te tuku i a rātou kia piri ki ngā mirumiru hau ka mānu ki te mata, ko ngā kohuke gangue ka noho tonu ki roto i te paru. He mea nui tēnei tikanga i roto i te painga o ngā konganuku kore-ferrous. Hei tauira, ka tae te tukatuka konganuku ki te wāhanga whakapūmau i muri i te kuru me te huri i roto i te tukatuka konganuku parahi, e whakaurua ai ngā kaikohi anionic motuhake hei whakarerekē i te hydrophobicity me te waiho i a rātou kia piri ki te mata o ngā kohuke parahi. Kātahi ka piri ngā matūriki parahi hydrophobic ki ngā mirumiru hau ka ara ake, ka hanga he paparanga o te pahuka e whakaatu ana i te parahi whai kiko. Ka kohia tēnei pahuka ki te kukū tuatahi o ngā kohuke parahi, hei rauemi mata kounga teitei mō te whakapai ake.
(2) Te Whakatere Whakamuri
Ko te whakamānutanga whakamuri ko te whakamānu i ngā kohuke gangue i te wā e noho tonu ana ngā kohuke utu nui ki roto i te paru. Hei tauira, i roto i te tukatuka rino me ngā poke quartz, ka whakamahia ngā kaikohi anionic, cationic rānei hei whakarerekē i te taiao matū o te paru. Ka huri tēnei i te āhua hydrophilic o te quartz ki te hydrophobic, ka taea ai e ia te piri ki ngā mirumiru hau me te mānu.
(3) Te Whakaterenga Manakohanga
Ina kei roto i ngā konganuku e rua, neke atu rānei ngā wāhanga utu nui, ka wehea ngātahitia ēnei e te mana whakatārewatanga pai i runga i ngā āhuatanga pēnei i te mahi kohuke me te uara ōhanga. Mā tēnei tukanga whakatārewatanga taahiraa-i-te-taahiraa ka whakarite kia whakahokia mai ia kohuke utu nui me te parakore teitei me ngā tere whakaora, kia nui ake ai te whakamahinga rauemi.
(4) Te Whakarewatanga Papatipu
Mā te whakapūmau papatipu ka rongoatia ngā kohuke whai hua maha, ka whakapūmau ngātahitia kia puta he ranunga kukū, ā, muri iho ka wehea. Hei tauira, i roto i te whakapūmautanga o te konganuku parahi-nikara, te wāhi e hono tata ana ngā kohuke parahi me te nikara, mā te whakapūmau papatipu mā te whakamahi i ngā matū pēnei i te xanthates, i te thiols rānei ka taea te whakapūmau i ngā kohuke parahi me te nikara i te wā kotahi, ka puta he ranunga kukū. Mā ngā tukanga wehenga matatini e whai ake nei, pēnei i te whakamahi i ngā matū raima me te cyanide, ka wehea ngā kukū parahi me te nikara tino parakore. Mā tēnei huarahi "kohikohi-tuatahi, wehe-muri" ka whakaitihia te ngaronga o ngā kohuke whai hua i ngā wāhanga tuatahi, ā, ka whakapai ake i ngā tere whakaora whānui mō ngā konganuku uaua.
2. Ngā Tukanga Whakarewa: He Tikanga Tikanga-i-te-Taumata
(1) Tukanga Whakaterenga Wāhanga: Whakamahinga Āpiti
I roto i te whakapūmau, ka ārahi te whakapūmau atamira i te tukatuka o ngā konganuku uaua mā te wehewehe i te tukanga whakapūmau kia maha ngā atamira.
Hei tauira, i roto i tētahi tukanga whakapūmau e rua ngā wāhanga, ka huri te konganuku, ka tukuna he wāhanga o ngā kohuke whai hua. Ka whakahokia mai ēnei kohuke whai hua i te wāhanga whakapūmau tuatahi. Ka haere ngā matūriki kāore anō kia tukuna ki tētahi wāhanga huri tuarua mō te whakaiti i te rahi, ā, ka whai ake ko tētahi wāhanga whakapūmau tuarua. Mā tēnei ka tino wehea ngā kohuke whai hua e toe ana, ā, ka honoa ki ngā kohuke whai hua o te wāhanga tuatahi. Mā tēnei tikanga ka ārai i te huri nui rawa i te wāhanga tuatahi, ka whakaiti i te moumou rauemi, ā, ka whakapai ake i te tika o te whakapūmau.
Mō ngā konganuku uaua ake, pērā i ngā mea kei roto he maha ngā konganuku onge me ngā hanganga tioata e herea pūmau ana, ka taea te whakamahi i tētahi tukanga whakapūmau e toru ngā wāhanga. Mā ngā mahi huri me te whakapūmau tauutuutu ka taea te tirotiro āta, ā, ka whakarite kia tangohia ia kohuke utu nui me te parakore teitei me te tere whakaora, ka whakatakoto i tētahi turanga pakari mō ngā tukatuka atu.
3. Ngā Take Matua i roto i te Whakaterenga
(1) Uara pH: Te Taurite Maeneene o te Waikawa o te Parai
He mea nui te uara pH o te paru ki te whakapūmau, e pā nui ana ki ngā āhuatanga o te mata o te kohuke me te mahi a te matū. Ina teitei ake te pH i te pūwāhi isoelectric o te kohuke, ka kino te mata; i raro iho, ka pai te mata. Mā ēnei huringa o te utu mata ka whakatau i ngā taunekeneke mimiti i waenga i ngā kohuke me ngā matū, he rite tonu ki te kukume, te pana rānei o ngā aukume.
Hei tauira, i raro i ngā āhuatanga waikawa, ka whai hua ngā kohuke whanariki mai i te kaha ake o te mahi kohikohi, kia māmā ake ai te hopu i ngā kohuke whanariki ūnga. I tetahi atu taha, ka āwhina ngā āhuatanga kawakore i te rere o ngā kohuke waikura mā te whakarerekē i ō rātou āhuatanga mata hei whakarei ake i te hononga matū.
He rerekē ngā kohuke e hiahia ana ki ngā taumata pH motuhake mō te whakamānutanga, me te whakahaere tika. Hei tauira, i roto i te whakamānutanga o ngā ranunga quartz me te calcite, ka taea te whakamānutanga i te quartz mā te whakarerekē i te pH paru ki te 2-3 me te whakamahi i ngā kaikohi i ahu mai i te amine. I tetahi atu taha, he pai ake te whakamānutanga o te calcite i roto i ngā āhuatanga kawakore me ngā kaikohi i ahu mai i te waikawa ngako. Ko tēnei whakarerekētanga pH tika te mea nui ki te whakatutuki i te wehenga kohuke whai hua.
(2) Te Pūnaha Whakaoho
Ko te pūnaha matū matū te kaiwhakahaere o te tukanga whakamānu, tae atu ki te kōwhiringa, te horopeta, te whakarite, me te tāpiri i ngā matū ...
Ka whakau ngā pahuka i ngā mirumiru i roto i te paru, ā, ka āwhina i te rere o ngā matūriki wai-kore. Ko ngā pahuka noa ko te hinu paina me te hinu cresol, e hanga ana i ngā mirumiru pumau, rahi pai hei whakapiri i ngā matūriki.
Ka whakahohe, ka aukati rānei ngā whakarerekētanga i ngā āhuatanga o te mata o ngā kohuke, ā, ka whakarerekē i ngā āhuatanga matū, hiko rānei o te paru.
Me tino tika te horopeta o te matū tauhohenga—ki te kore e ranea ngā rahinga ka whakaiti i te wai-whakaaro, ka whakaiti i ngā tere whakaora, engari ko te nui rawa ka moumou i ngā matū tauhohenga, ka piki ake ngā utu, ā, ka whakararu i te kounga o te kukū. Ngā taputapu atamai pēnei i temita kukū ipurangika taea te whakahaere tika i te horopeta o te matū matū.
He mea nui anō hoki te wā me te tikanga o te tāpiri i te matū. He maha ngā wā ka tāpirihia ngā kaiwhakatikatika, ngā mea whakaiti i te kaha, me ētahi kaikōhikohi i te wā e huri ana hei whakarite i te taiao matū o te paru i te wā tuatahi. Ko ngā kaikōhikohi me ngā mea whakapūpū ka tāpirihia ki te tāke whakapūpū tuatahi hei whakanui ake i tōna whai huatanga i ngā wā tino nui.
(3) Te Tere Whakapūngao
Mā te tere o te hau ka hangaia he āhuatanga tino pai mō te piri o te kohuke-mirumiru, ka waiho hei mea nui mō te whakamānu. Ki te kore e ranea te hau ka iti rawa ngā mirumiru, ka whakaiti i ngā whai wāhitanga tukinga me te piri, ā, ka whakararu i te mahi whakamānu. Nā te nui rawa o te hau ka nui rawa te aueue, ka pakaru ngā mirumiru, ka wetekina ngā matūriki e piri ana, ka whakaiti i te whai huatanga.
Ka whakamahia e ngā miihini ngā tikanga pēnei i te kohikohi hau, te ine rānei i te rere o te hau e ahu mai ana i te anemometer hei whakatikatika i ngā tere o te hau. Mō ngā matūriki taratara, mā te whakanui ake i te hau hei whakaputa mirumiru nui ake ka pai ake te rere o te hau. Mō ngā matūriki taratara, ngā matūriki ngāwari rānei te rere, mā ngā whakatikatika āta whakarite kia pumau, kia whai hua hoki te rere o te hau.
(4) Te Wā Whakamānu
He taurite te wā mānu i waenga i te taumata kukū me te tere whakaora, me whakarite kia tika. I ngā wāhanga tōmua, ka piri tere ngā kohuke whai hua ki ngā mirumiru, ka hua ake he tere whakaora teitei me ngā taumata kukū.
I roto i te wā, i te mea ka mānuhia ngā kohuke nui ake, ka piki ake pea ngā kohuke gangue, ka memeha te parakore o te kukū. Mō ngā konganuku māmā he matotoru ake te kiri, ā, he ngāwari te mānu, he poto ake ngā wā mānu, kia tere ai te whakaora me te kore e whakaiti i te kounga kukū. Mō ngā konganuku uaua, ā, he ātete rānei, me roa ake ngā wā mānu kia nui ai te wā taunekeneke a ngā konganuku pai ki ngā matū me ngā mirumiru. Ko te whakarerekētanga hihiri o te wā mānu he tohu nui o te hangarau mānu tika me te whai hua.
