Nā Mea Maka Hoʻomaʻemaʻe ʻia ka Aluminium trihydrate mai ka bauxite. Loaʻa nā waihona bauxite kalepa (30-75% Al2O3) ma Australia, Jamaica, Farani, Guyana, Guinea, USA a me Brazil. Hoʻoheheʻe ʻia ka ʻaila bauxite i loko o ka soda caustic ikaika e hana i ka sodium aluminate. A laila hoʻoheheʻe ʻia ka aluminium trihydrate e ka neutralization (maʻamau me ke kalapona dioxide) a i ʻole ma ka autoprecipitation (ke kaʻina hana Bayer). ʻO ka mea maka ʻē aʻe, ka waikawa sulfuric, hana ʻia no ka hana superphosphate ma Farmers Fertiliser Ltd. Hōʻea ka waikawa ma ka moku tanker alanui a hoʻopili ʻia i loko o nā pahu mālama.
KaʻAnuʻu Hana 1 - Ke hana hou ʻana i nā mea hoʻohui maka. Lawe ʻia a mālama ʻia ka alumini trihydrate i loko o hoʻokahi tona ʻeke. Lawe ʻia kēlā me kēia ʻeke ma ka hāpai i ka hopper hānai, kahi e wehe ʻia ai a lawe ʻia i ka pahu hana. Hoʻoulu ʻia ka wai hana, ka trihydrate a me ka sulfuric acid batch no kekahi manawa me ka mahu wai e puka ana ma o ka puʻu.
KaʻAnuʻu Hana 2 - Ke Hana ʻana i ka huahana hope loa Ma hope o ka manawa hana, hana ʻia ka alum wai a paʻa paha. Inā wai, holo ka ʻāpana i hoʻopaʻa ʻia i loko o ka pahu dilution i piha i ka wai dilution kahi e hoʻomaʻalili ai i ka hala ʻana o ka manawa. A laila kānana ʻia ka alum wai a hoʻopuehu ʻia i ka mālama ʻana. Aia nā hale hoʻouka ma luna ma Morrinsville kahi i loaʻa ai ka nui o nā kemika wai i loko o nā pahu hoʻouna no nā tankers alanui. Inā hana ʻia ka paʻa, holo ka alum i hoʻopaʻa ʻia i loko o nā pā hoʻolei kahi e hoʻopaʻa ai, me ke kōkua o ka hoʻoluʻu ʻana o ka peʻahi. Hoʻouka ʻia nā pā i nā ʻūlū mālama a mai laila aku e lawe ʻia ai lākou i ka Crushing Plant a hoʻokuʻu ʻia i loko o kahi hopper. Ua wāwahi hou ʻia nā ʻāpana e kahi kibbler nui a ukali ʻia e kahi kibbler liʻiliʻi a laila kānana ʻia. Hele nā ʻāpana nui i kahi hopper bagging a kūʻai ʻia aku ma ke ʻano he huahana kibbled. Kuʻi ʻia ka alum i kānana ʻia ma ka rotary a kānana hou ʻia e hoʻi i ka rotary crusher a i ʻole e ʻeke ʻia ma ke ʻano he huahana lepo. Hōʻiliʻili mau ʻia ka lepo ma o kahi ʻōnaehana unuhi a kūʻai ʻia aku ma ke ʻano he huahana. He maʻalahi ka Crushing Plant a he loli ka lakio o ka kibbled i ka alumini sulfate lepo.
