Uburyo bwo gukora sulfate ya aluminiyumu

Ibikoresho fatizo bya Aluminium trihydrate bisukurwa bivuye kuri bauxite. Ibice bya bauxite byo mu bucuruzi (30-75% Al2O3) biba muri Ositaraliya, Jamayika, Ubufaransa, Guyana, Guinée, Amerika na Brezili. Ubutare bwa Bauxite bushongeshwa muri soda ikomeye ya caustic kugira ngo habeho sodium aluminate. Hanyuma trihydrate ya aluminium iterwa no kugabanya (ubusanzwe hamwe na dioxyde de carbone) cyangwa na autoprecipitation (uburyo bwa Bayer). Ibindi bikoresho fatizo, aside sulfurike, bikorwa kugira ngo bikore superphosphate muri Farmers Fertiliser Ltd. Aside iza mu bwato butwara imizigo ikajugunywa mu bigega byo kubikamo.

Intambwe ya 1 - Guhindura ibintu by’ibanze. Ifu ya aluminiyumu itwarwa ikabikwa mu mufuka wa toni imwe. Buri mufuka utwarwa hakoreshejwe icyuma gikurura ujya mu gikoresho cyo kugaburira, aho ufungurwa ugashyirwa mu kigega cyo kugaburira. Amazi ya reaction, trihydrate na aside sulfurike bivangwa igihe runaka, umwuka w’amazi ukava mu gipfunyika.

Intambwe ya 2 - Gukora umusaruro wa nyuma Nyuma y'igihe cyo gukora, haba amazi cyangwa alum ikomeye. Iyo ari amazi, igice cyuzuyemo amazi cyuzuyemo amazi ayungurura aho akonja uko igihe kigenda. Hanyuma alum y'amazi irayungururwa ikanashyirwa mu bubiko. Hariho ibikoresho byo gusohora amazi hejuru i Morrinsville aho imiti myinshi y'amazi iboneka mu bigega byo kohereza amatanki yo mu muhanda. Iyo hakozwe ibintu bikomeye, alum ikomeye ishyirwa mu masafuriya aho ishyirwa, ifashijwe no gukonjesha umufana. Amasafuriya ashyirwa ku byuma byo kubikamo amazi, hanyuma akajyanwa mu ruganda rusya amazi hanyuma akajugunywa mu cyuma gifunga. Ibice binini cyane bishyirwa mu cyuma gifungamo amazi maze bikagurishwa nk'ibicuruzwa byaciwe. Alum yaciwemo amazi iracukurwa ikanasuzumwa kugira ngo igaruke mu cyuma gifungamo amazi cyangwa igashyirwa mu cyuma gifungamo amazi. Ivumbi rihora rikusanywa binyuze mu buryo bwo gukurura amazi kandi rigurishwa nk'ibicuruzwa. Uruganda rusya ibintu rurimo ubushobozi bworoshye kandi igipimo cya sulfate ya aluminiyumu ishaje n'icyatsi kirahinduka.
