Zinthu zopangira Aluminium trihydrate zimayeretsedwa kuchokera ku bauxite. Ma depositi a bauxite ogulitsa (30-75% Al2O3) amapezeka ku Australia, Jamaica, France, Guyana, Guinea, USA ndi Brazil. Mafuta a Bauxite amasungunuka mu soda yamphamvu kuti apange sodium aluminate. Kenako ma trihydrate a aluminiyamu amasungunuka ndi kuchepetsedwa mphamvu (nthawi zambiri ndi carbon dioxide) kapena ndi autoprecipitation (njira ya Bayer). Zinthu zina zopangira, sulfuric acid, zimapangidwa kuti zipange superphosphate ku Farmers Fertiliser Ltd. Asidi amafika ndi sitima yonyamula katundu ndipo amapopedwa m'matanki osungiramo zinthu.
Gawo 1 - Kugwirana ndi zosakaniza zosaphika. Aluminiyamu trihydrate imanyamulidwa ndikusungidwa m'matumba a tani imodzi. Thumba lililonse limanyamulidwa ndi chokwezera kupita ku feed hopper, komwe limatsegulidwa ndikutumizidwa ku thanki yochitirana. Madzi a reaction, trihydrate ndi sulfuric acid batch amasunthidwa kwa nthawi ndithu ndi nthunzi yamadzi kutuluka kudzera mu mulu.
Gawo 2 - Kupanga chinthu chomaliza Pambuyo pa nthawi yochitapo kanthu, alum yamadzimadzi kapena yolimba imapangidwa. Ngati ndi yamadzimadzi, gulu lokhuthala limayikidwa mu thanki yosungunuka yodzazidwa ndi madzi osungunuka komwe imazizira pakapita nthawi. Alum yamadzimadzi imasefedwa ndikupopedwa kuti isungidwe. Pali malo otulutsira mafuta pamwamba pa Morrinsville komwe mankhwala ambiri amadzimadzi amapezeka m'matanki otumizira matanki amisewu. Ngati yolimba imapangidwa, alum yokhuthala imayikidwa mu mapani oponyeramo mafuta komwe imakhazikika, mothandizidwa ndi kuzizira kwa fan. Mapaniwo amanyamulidwa ku foloko kupita ku malo osungiramo zinthu ndipo kuchokera pamenepo amatengedwa kupita ku Crushing Plant ndikuponyedwa mu hopper. Zidutswazo zimasweka kwambiri ndi kibbler yayikulu kutsatiridwa ndi kibbler yaying'ono kenako nkutsukidwa. Tinthu tating'onoting'ono timapita ku hopper yosungiramo katundu ndipo timagulitsidwa ngati chinthu chosungunuka. Alum yotsekedwa imaphwanyidwa mozungulira ndikutsukidwanso kuti ibwerere ku rotary crusher kapena kusungidwa mu thumba ngati chinthu chophwanyidwa. Fumbi limasonkhanitsidwa nthawi zonse kudzera mu njira yotulutsira ndipo limagulitsidwa ngati chinthu. Chomera Chophwanyira chimasinthasintha ndipo chiŵerengero cha sulfate ya aluminiyamu yophwanyidwa ndi nthaka chimasinthasintha.
