Ko te paru kani he ranunga o te paura kōhatu me te wai i puta i te wā e tapatapahia ana, e whakakanapahia ana te māpere me te karāneti. He maha ngā wāhi kei te raki o tō tātou whenua he pūtake tukatuka kōhatu nui, ā, he nui te paru kani e puta ana i ia tau, ā, he nui te whenua e kapi ana i te puranga. He pai te kakano o te paura kōhatu, ā, he uaua ki te maka atu. He ngāwari ki te rere i te rangi i te hau kaha, ā, ka rere ki te awa me te wai ua i ngā rā ua, ka puta he parahanga nui ki te taiao.
Ko ngā kohuke gangue matua i roto i te paru kani ko te feldspar, te quartz, te calcite, te dolomite, te amphibole, me ētahi atu. Ko ngā kohuke me ngā poke matua ko te silicate rino pērā i te rino miihini, te magnetite, te waikura rino, te pyrite, me te biotite. I tēnei wā, ko te tikanga whakamahi whānui o te paru kani ko te whakaputa pereki hau raima me te hanga rauemi mata uku i muri i te tango i ngā poke. He nui te kaha tukatuka o te tuatahi, ā, he nui ngā painga ōhanga o te tuarua.
Rangahau painga
I roto i tēnei tuhinga, ka whakahaerehia te rangahau whānui mō te whakamahinga me te whakamātautau painga mō te paru kani e tohu ana i te rohe o Jining. Ko ngā kohuke nui o te paru kani ko te feldspar, te rino miihini, te rino aukume, me ētahi atu, ā, ko ngā poke kino ko te limonite, te biotite, te muscovite, te calcite, te dolomite, te hornblende, me ētahi atu. Kāore i te ōrite te rahi o te rauemi, ko ngā matūriki matotoru kei waenga i te 1-4mm me te paru pai -0.037mm. I roto i ēnei, ko te rino miihini i hangaia i te wā tukatuka me te rino aukume i roto i te konganuku mata ka taea te wehe mā te aukume ki ngā hua rino kukū. I muri i te wehenga aukume kaha, ka taea te tango i ngā poke kei roto te rino pērā i te limonite, te biotite, me te amphibole. Ko ngā hua kukū kōhatu, ko ia wāhanga o ngā toenga aukume ka taea te whakamahi hei pereki hau, hei rauemi sima rānei, kia tutuki ai te kaupapa o te whakamahinga whānui.
1.Te whakatau i te rere o te tukanga
Te whakakotahi i ngā āhuatanga o te tauira wahie hei whakatau i te tukanga whakangawari: ka tātarihia te konganuku mata mā roto i te hurihanga 30 mata-+30 mata ki te -30 mata.
——-Wehenga rino tauira whakauru 30 mata mā te wehewehe aukume pahu + pereti papatahi + mowhiti poutū + mowhiti poutū tango rino aukume kaha -ka whakarōpūtia te kukū ki ngā hua kukū feldspar waenga-kikorangi +300 mata me te paru pai -300 mata——Kātahi ka whakamahia te paru angiangi hei tango i te rino kia rua ngā wā mā te paru hikohiko hei whakaputa i tētahi hua kukū paura angiangi.
2.Whakamātautau wehenga aukume o te konganuku mata
I tātarihia te konganuku mata ki ngā mata 30, ā, e whakaaturia ana ngā hua tātari i te Ripanga 1.
Ripanga 1. Hua o te Whakamātautau Painga me te Tātaritanga
Hurihia te konganuku matotoru me te hua o te 17.35% ki te -30 mata, whakaranua ki te hua i raro i te tatari, ka haere i roto i te tukanga wehenga aukume tikanga o te wehenga aukume pahu + pereti papatahi + mowhiti poutū + mowhiti poutū. Kei te whakaatuhia te rere o te tukanga i te Pikitia 1, ā, kei te whakaatuhia ngā hua whakamātautau i te Ripanga 2.
Pikitia 1. Te rere o te tukanga whakamātautau wehenga aukume tikanga o te konganuku mata.
Ripanga 2. Ngā hua o te whakamātautau wehenga aukume tikanga
Ka tirotirohia te konganuku mata + ka huri konganuku + ka whakamātautauhia kia toru ngā wā tango rino, ā, ka taea te whiwhi i ngā hua kukū waenga me te iti me te hua o te 92.57%, te ihirangi Fe2O3 o te 0.525% me te mā o te 36.15%. Me whakaaro ki te pure i te waikura rino pai me te silicate rino i roto i te paru pai me te mīhini paru hiko reo pai, mara-teitei i muri i te whakarōpūtanga.
3. Te tango rino mai i te paru paru pai
Ka tukuna te tuarua o ngā matū kukū o Lihuan mai i te paru pai i raro i te -300 mesh mā te waipuke, ā, ka whakamahia te tukanga tango rino e rua ngā wā mā te mīhini paru hikohiko hei tiki i te hua kukū paura pai. Kei te Whakaahua 2 te rere o te tukanga, ā, kei te Ripanga 3 ngā hua whakamātautau.
Pikitia 2. Te rere o te tukanga whakamātautau tango rino paru pai
Ripanga 3. Taupū tango rino o te paru paru pai
I muri i te whakarōpūtanga o te kukū Lihuan, ka piki ake te mā o te kukū feldspar kakano-waenga +300 mesh mai i te 36.15% ki te 56.49%, ā, ka heke te mā o te paru pai ki te 23.07%. Ka tangohia te paru pai -300 mesh mai i te rino e rua ngā wā mā te para hikohiko, ā, ka taea te whiwhi i tētahi paura pai karaehe uku me te hua o te 42.31% me te mā o te 41.80%.
3. Whakamātautau tukanga katoa
Ngā tikanga whakamātautau whānui me ngā tohu hei mahi i te whakamātautau tukanga katoa.
Pikitia 3. Te tukanga katoa o te whakamātautau paru kani
Ripanga 4. Ngā tohu whakamātautau mō te tukanga katoa
Āpitihanga: Te pāmahana pihikete 1200℃
Ka tātarihia te konganuku paru kani + ka hurihia + ka wehea te konganuku aukume ngoikore + ka pereti papatahi + karaka poutū + karaka poutū + ka whakarōpūhia te tukanga wehenga aukume paru aukume hikohiko hei whiwhi i te konganuku rino me te hua o te 0.32% me te tohu TFe o te 62.35%. Me te hua o te 38.56% me te mā o te 54.69% o ngā hua kukū feldspar uku-waenga me te hua o te 42.31% o te mā o ngā hua kukū uku paura pai o te 41.80%; ko te hua katoa o ngā paru aukume he 18.81%, ka taea te whakamahi hei rauemi mata mō ngā pereki hau.
Mā tēnei tukanga hangarau ka taea te whakamahi whānui i ngā paru paru kani, ā, ka taea hoki te whiwhi i ngā painga ōhanga me te hiranga ki te tiaki taiao pāpori.
