Ko te toka phosphate e pā ana ki te kupu whānui mō ngā kohuke phosphate ka taea te whakamahi ōhanga, ko te kohatu apatite me te toka phosphate te nuinga. Ko te phosphorus kōwhai, te waikawa phosphoric, te phosphide me ētahi atu phosphate e whakamahia ana i roto i te rongoā, te kai, ngā mati, ngā tae, te huka, te uku, te tiaki whenua me ētahi atu mara ahumahi.
Ngā Āhuatanga o te Kohuke me te Hanganga o te Kohuke
E 120 pea ngā momo kohuke kei roto te whākawa e mōhiotia ana i te taiao, engari ko ngā kohuke ahumahi kei roto te whākawa he kohuke phosphate i roto i te apatite me te toka phosphate. Ko te Apatite [Ca5(PO4)3(OH,F)] he kohuke ko tōna wāhanga matua ko te konupūmā phosphate. He rerekē ōna ingoa nā runga i ngā momo huānga kei roto, pērā i te fluorine me te chlorine. Ko ngā kohuke kei roto te whākawa ko: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, me ētahi atu. Ko te ihirangi ariā o te P2O5 kei waenga i te 40.91 me te 42.41%. Ka taea e ngā anion F, OH, CO3, me te O tāpiri i roto i te toka phosphate te whakakapi tetahi i tetahi, ā, he maha ngā wāhanga isomorphic, nō reira ka tino rerekē te hanganga matū o te kohuke.
Te hanganga matū noa o te apatite
- Ngā wāhanga matū 2. Ngā ihirangiNgā rohe tono me ngā whakaritenga taupūKo te toka phosphate te nuinga o te wā e whakamahia ana hei rauemi mata mō te tongi waikawa phosphoric me ngā momo matū phosphoric, ā, e whakamahia whānuitia ana i roto i ngā mara o te ahumahi matū, te rongoā, ngā patu pepeke, te ahumahi māmā me te ahumahi hōia.Hangarau TukatukaTe painga me te purenga
Ka taea te wehewehe i te toka phosphate ki te momo siliceous, te momo calcareous, me te momo silicon (conazole)-calcium (silicon). Ko ngā kohuke e pā ana ko te nuinga o te quartz, te flint, te opal, te calcite, te feldspar, te mika, te limestone, te dolomite, te onewood onge. , magnetite, ilmenite, limonite, me ētahi atu, ko te tikanga whakapūmau te tikanga whakangao nui rawa atu mō te apatite.
Ko te tukanga hangarau matua ko: te tukanga whakakotahi i te whakapūngao + te wehenga aukume, te huri + te whakarōpū + te whakapūngao, te huri ā-wāhanga + te wehenga ā-wāhanga, te tunu + te nakunaku + te whakarōpū.
Te whakawehe aukume whakamātao hinu-wai whakapūmau porowhita teitei
Te Tukatuka i ngā Matū Phosphate o ngā Tongi Phosphate
Ko te hanga tongi phosphate he huri i ngā kohuke phosphate ki ngā phosphate ka ngawari te mimiti e ngā tipu mā te tukanga whakangawari, te pāmahana teitei, me te hanga. Ko te ammonium phosphate he tongi matū whai hua nui i hangaia mai i te waikawa phosphoric i roto i te wai haukini. Ka whiwhihia te phosphorus kōwhai mā te whakamahana i te toka phosphate i konatunatua ki te onepu quartz me te coke i te 1500°C i roto i te oumu hiko. E rua ngā tikanga hanga o te waikawa phosphoric: te tikanga tango waikawa whanariki me te tikanga mimiti tahunga peroxy.
Tauira painga
Ko te matotoru o ngā paru rino i Hebei he -200 mata, ko te 63.29% te nui, ko te tapeke o te ihirangi rino TFe he 6.95%, ā, ko te ihirangi P2O5 he 6.89%. Ko te rino te nuinga he waikura rino pērā i te limonite, te silicate rino me te magnetite i roto i te āhua o ngā whakaurunga tonu; ko ngā kohuke kei roto te phosphorus ko te nuinga he apatite, ko ngā kohuke gangue ko te quartz, te feldspar, te calcite, me ētahi atu. He tata ake te hono atu ki ngā kohuke phosphorus. Ko te kaupapa o te whakamātautau he tīpako i ngā kohuke whai rino mā te wehenga aukume, ā, ka whakanuia te apatite i roto i ngā paru wehenga aukume.
E ai ki ngā āhuatanga o ngā tauira, ka whakatauhia te tukanga whakangawari penei: ko te konganuku mata kua tīpakohia – 200 mata me te matotoru o te 63.29%, ka hangaia hei paru me te kukū o te 30%, ā, ka tīpakohia te rino aukume tonu e te papa aukume ngoikore CTB4000GS, ā, ka tīpakohia ngā toenga e te mowhiti poutū 0.5T waikura rino aukume ngoikore me ngā kohuke silicate rino.
Te rere o te tukanga whakamātautau tango rino wehenga aukume o ngā toenga rino kei roto he ūkuikui
Kua oti ngā toenga rino kei roto he whākawa rino te tango i te rino, arā, kotahi te tārai me te kotahi te horoinga e rua ngā wā, ā, kāore i taea te whiriwhiri i ngā hua rino kukū kua tohua mai i te rauemi aukume. I piki ake te ihirangi whākawa i roto i te kukū matotoru whākawa mai i te 6.89% ki te 10.12%, ā, ko te tere whakaora whākawa he 79.54%. %, ko te tere tango rino he 75.83%. I roto i te whakamātautau whakatairite i ngā kaha mara rerekē o Lihuan 0.4T, 0.6T me te 0.8T, i kitea ko te kaha mara iti o Lihuan 0.4T i hua ake ai he nui rawa te rino i roto i te whākawa matotoru me te kua whakapaia, ā, ko te kaha mara teitei o te 0.8T i puta ai te ngaronga o te whākawa i roto i ngā rauemi aukume. Nui. He pai te whiriwhiri i ngā tikanga wehenga aukume e tika ana hei whakapai ake i te taupū painga o te mahi whakatārewatanga o te toka phosphate o raro.
