Ngā Rauemi Mata Ka purea te konumohe trihydrate mai i te bauxite. Kei Ahitereiria, Jamaica, France, Guyana, Guinea, USA me Brazil ngā putunga bauxite arumoni (30-75% Al2O3). Ka whakarewaina te konganuku bauxite ki roto i te houra caustic kaha hei hanga i te konutai aluminate. Kātahi ka whakapūpūtia te konumohe trihydrate mā te whakakorenga (te nuinga o te wā me te hauhā waro) mā te autoprecipitation rānei (te tukanga Bayer). Ko tētahi atu rauemi mata, te waikawa whanariki, ka hangaia mō te hanga superphosphate i Farmers Fertiliser Ltd. Ka tae mai te waikawa mā te waka tāke rori ka papua ki roto i ngā tāke rokiroki.
Hipanga 1 – Te tauhohenga o ngā kai mata. Ka haria te konumohe trihydrate, ka rongoatia ki roto i ngā putea kotahi tana. Ka haria ia putea mā te hiki ki te ipu whāngai, ka whakatuwheratia, ka haria ki te tāke tauhohenga. Ka whakaohokia te wai tauhohenga, te trihydrate me te puranga waikawa whanariki mō tētahi wā, ka puta te mamaoa wai mā roto i te puranga.
Hipanga 2 – Te Hanga i te Hua Whakamutunga I muri i te wā tauhohenga, ka hangaia he konumohe wai, he konumohe totoka rānei. Mena he wai, ka rere te puranga kukū ki roto i te tāke waimeha kua whakakiia ki te wai waimeha, ka whakamatao i roto i te wā. Kātahi ka tātarihia te konumohe wai, ka papuhia ki te rokiroki. He wāhi utaina i runga ake i Morrinsville kei reira he maha ngā matū wai e wātea ana i roto i ngā tāke tuku mō ngā waka tāke rori. Mena ka hangaia he totoka, ka rerehia te konumohe kukū ki roto i ngā peihana whakarewa, ka totoka, me te āwhina a te hau whakamatao. Ka haria ngā peihana ki ngā whata rokiroki, ā, mai i reira ka haria ki te Wāhi Pakaru ka tukuna ki roto i te hopper. Ka pakaruhia anō ngā wahi e te kibbler nui, ā, muri iho ka whai te kibbler iti, kātahi ka tirotirohia. Ka haere ngā matūriki nunui ki te hopper putea, ka hokona hei hua kibbled. Ka kuruhia te konumohe kua tirotirohia ki te hurihuri, ka tirotirohia anō kia hoki ki te kibbler hurihuri, kia kapi rānei hei hua whenua. Ka kohia tonutia te puehu mā te pūnaha tango, ā, ka hokona hei hua. He ngāwari te Wāhi Pakaru, ā, he rerekē te ōwehenga o te konumohe whanariki kua kibbled ki te whenua.
