Ko te phosphate rewa e pā ana ki te phosphate rewa kua konatunatua ki te waikawa phosphoric, ki te phosphate rānei, ā, e pā ana tōna tikanga whakapakeke ki te momo here i whakamahia me te tikanga whakapakeke.
Ko te mea e herea ai te phosphate rewa ka taea te whakamahi i te waikawa phosphoric, i te ranunga rānei o te konumohe dihydrogen phosphate i hangaia mā te tauhohenga o te waikawa phosphoric me te konumohe hydroxide. I te nuinga o te wā, kāore te mea e herea ai me te konumohe silicate e tauhohe i te pāmahana rūma (haunga te rino). Me whakamahana kia maroke, kia whakakōpiripiritia te mea e herea ai, kia honoa ai te paura kopa kia whiwhi ai i te kaha i te pāmahana rūma.
Ina whakamahia te matū whakapūkara, kāore e hiahiatia he whakamahana, ā, ka taea te tāpiri i te paura konupūmā pai, te sima alumina nui rānei hei whakatere i te whakapūkara. Ina tāpirihia te paura konupūmā waikura pai, ka tere te tauhohe ki te waikawa phosphoric, ka puta he rauemi ātete ki te whakapūkara, ā, ka whakapakeke. Ina tāpirihia te sima aluminate, ka puta he phosphates he pai ngā āhuatanga whakapūkara, arā, he phosphates kei roto he wai pērā i te konupūmā monohydrogen phosphate, te diphosphate rānei. Mā te hauwai konupūmā, me ētahi atu, ka whakapūkara, ka whakapakeke te rauemi.
Mai i te tikanga whakapakeke o ngā mea whakarewa waikawa phosphoric me te phosphate, e mōhiotia ana ko te tere tauhohenga i waenga i te sima me ngā konganuku me ngā paura awhiowhio anake ka taea te hanga i tētahi mea whakarewa awhiowhio pai rawa atu. Heoi, ka ngāwari te whakauru i ngā rauemi mata awhiowhio ki te tukanga kuru, te mira pōro me te whakaranu. Ka tauhohe rātou ki te kaihoko sima ka tukuna te hauwai i te wā whakaranu, ka pupuhi te mea whakarewa awhiowhio, ka pakaru te hanganga me te whakaiti i te kaha pēhi. He mea kino tēnei mō te hanga i ngā mea whakarewa waikawa phosphoric me te phosphate noa.
