I raro i te kaupapa o te whakahoutanga ahumahi o te ao, i reirate matotoru teitei, te pumau matū, te mā parakore me te whai hua o te utute tautuhi i te whakataetae rauemi,paura parite—i whakapaia mai i te konganuku barite tūturu (barium sulfate)—kua puta ake hei whakakī matua kore e taea te whakakapi. He nui atu i te tāpiri ahumahi noa, he whakaurunga tino pai ote parakore o ngā kohuke tūturu me te hangarau tukatuka hohonu, te tautuhi anō i ngā paerewa o ngā whakakī taumaha, ngā whakaroa mahi teitei me ngā rauemi mahi ahumahi. E mōhiotia ana ko "te pou tuara taumaha o te ahumahi hou", ka tukuna e te paura baryte ngā painga kāore i te rite i roto ite taumaha motuhake teitei, te ātete waikawa-kawakore, te kore-paitini, te mā teitei me te tino pai o te whakamararatanga, e whakamana ana i te whakapai ake i te kounga puta noa i ngā ahumahi me te whanaketanga tauwhiro.

Ko te uara matua o te paura baryte kei roto i tōnangā āhuatanga taiao ahurei me te whakahaere tukatuka tika. E whakahaerehia ana epāriuma whanariki (BaSO₄ ≥ 94%), he āhuatanga o te paura baryte kounga teiteite taumaha motuhake teitei o te 4.2–4.5 g/cm³, he nui atu i ngā whakakī kohuke noa. Ka whai i te kōwhiringa tino pakari o te kohuke, te kuru, te huri pai, te purenga me te whakarerekētanga mata, ka tutuki ai ngā rahi matūriki ka taea te whakarite mai i200 mata ki te 3000 matahe rite te tohatoha. He ngoikore te matū, kāore e wairewa i roto i te wai, i ngā waikawa me ngā kawakore, ātete ki te huarere, te koroheketanga me te waikura, me te mahi pumau i raro i ngā pāmahana tino kino me ngā taiao uaua. Ko tōna āhua tūturute mā nui (≥90)me te iti o te poke ka whakakore i te pokanoa o te tae, ko ngā āhuatanga kore-paitini me te kore-kino e tutuki ana i ngā paerewa REACH, RoHS me te haumaru pā-kai—he tauira tēnei o ngā rauemi kohuke haumaru, pumau, me te hoa-taiao.

Me ōna kaha ā-roto, e whakaatu ana te paura baryte i te whānuitanga o ngā mahi, e whakaoti ana i ngā raruraru matua puta noa i ngā rāngai ahumahi kanorau.ngā paninga me ngā peita, he mea whakaroa mahi-teitei me te whakakī ārai-taunga mō ngā pūnaha whakarewa-hanga, wai-hanga me te polyurethane 2K, e whakarei ake ana i te pakeke o te kiriata peita, te ātete ki te rakuraku, te ātete ki te totohu me te ātete ki te huarere, me te whakapai ake i te kanapa me te whakaiti i te whakamahinga kapia. I roto ikirihou me te rapa, he mea whakahaere kiato, he mea whakakī whakakaha hoki, e whakanui ana i te taumaha o te hua, te pakari, te pumau o ngā āhuatanga me te ārai haruru mō ngā paipa, ngā kōtaha, ngā wāhanga motuka me ngā wāhanga hiko. I roto ite keri hinu me te hau, koinei te taumaha matua mō te keri paru, te whakahaere i te pēhanga o te puna me te aukati i ngā pupuhi. I roto ingā ahumahi hanga me te matū, e whakamahia whānuitia ana i roto i ngā piripiri, ngā hiri, ngā paninga uku, te hanga pepa me ngā rauemi ātete-irahiko, e whakawhānui ana i tōna uara mai i te hanga ahumahi ki ngā mara mahi teitei.

Nā te auahatanga hangarau me te tono a te mākete, kua uru te umanga paura baryte ki tētahi wāhanga o te whanaketanga kounga teitei. Ngā putanga hou i roto ite huri tino pai, te whakarerekētanga nano me te whakarōpū mohiokua hurihia te paura baryte mai i tētahi rauemi papatipu iti te utu heiwhakakī mahi whakarite utu nui, e tutuki ana i ngā whakaritenga pakari mō te tika o te rahi o te matūriki, te ōritetanga o te puranga me te mahi mata. Ka whakamahia e te whakaputanga hou te tukatuka ara-kati, te tirotiro kounga aunoa me ngā pūnaha huri iti-pūngao, e tutuki aite ōritetanga o te rahi matūriki o te 99.4%, te rerekētanga puranga ≤1.0% me te kore parahanga konganuku taumahaHei kaiārahi o te ao i ngā rauemi barite, e whakamanamana ana a Haina ki ngā rahui nui me te mekameka ahumahi katoa e kapi ana i te keri, te tukatuka hohonu me te tuku taputapu. Ka kaweakehia ana hua paura barite kounga teitei ki te neke atu i te 60 whenua me ngā rohe, ka tere ake te whakakapinga o ngā whakakī kounga teitei kawemai.

I tēnei wā o te arotautanga ahumahi o te ao me te hanga matomato, kei te piki haere tonu te hiranga rautaki o te paura baryte. He tino ōrite ki ngā whāinga whanaketanga ongā rauemi mahi teitei, te whakaiti utu me te ōhanga porowhita, e whakarato ana i tētahi huarahi tūturu, pumau, ā, pumau hoki hei whakakapi i ngā whakakī hangai. Kua hipa te rahi o te mākete o te ao mō te paura baryte3.2 piriona tāra tāra i te tau 2025, ā, i hipa ake te mākete HainaRMB 4.6 pirionaE matapaetia ana ka eke te rahi o te mākete o te paura baryte kua whakarerekētia he parakore teitei kiRMB 42 piriona i te tau 2030, i te mea e whai ana ngā ahumahi i te kiato teitei, te pumau me te haumaru. Mai i te kohuke taumaha tuku iho ki tewhakakī mahi matua mō te hanga hou, e whakaatu ana te paura baryte ka taea e ngā kohuke taiao te tautoko i te ahunga whakamua o te ahumahi me te kounga parakore me te mahi pono. Ehara i te mea he rauemi ahumahi taketake, engari he pou matua mō te hanga i tētahipūnaha ahumahi hou, mahi teitei, pumau, me te pumau, e ārahi ana i ngā ahumahi o te ao ki tētahi heke mai e whai hua ake ana, e pono ake ana hoki.
