Bauxite (bauxite ore) na-ezo aka n'okwu mkpokọta maka mineral ndị enwere ike iji na ụlọ ọrụ, nke kachasị nke gibbsite, boehmite, ma ọ bụ diaspore. Ọ bụ akụrụngwa enweghị ike imeghari. Bauxite dị ọcha na-acha ọcha na agba ma nwee ike ịpụta ìhè isi awọ, akwụkwọ ndụ akwụkwọ ndụ dị ọkụ, ma ọ bụ na-acha uhie uhie n'ihi adịghị ọcha dị iche iche. Bauxite nwere ọtụtụ ngwa ụlọ ọrụ mmepụta ihe. N'otu aka ahụ, ọ bụ isi akụrụngwa maka ịmepụta alumina, nke na-emepụta aluminum. N'aka nke ọzọ, a na-eji ya eme ihe n'ọtụtụ ebe dị ka ihe eji eme ihe na ụlọ ọrụ ndị dị ka ihe mgbagha, corundum fused, ihe egweri, ngwaahịa seramiiki, ngwaahịa kemịkalụ, na nnukwu alumina slurry.

 

Calcined bauxite nwere alumina hydrated na aluminom hydroxide, enwetara site na ịgbakọ bauxite dị elu na okpomọkụ dị elu (85°C ruo 1600°C) n'ime igwe rotary. Ọ bụ otu n'ime ihe ndị bụ isi maka imepụta aluminom. E jiri ya tụnyere nke mbụ bauxite, mgbe iwepu mmiri site na calcination, enwere ike ịbawanye ọdịnaya alumina nke calcined bauxite site na ihe dịka 57% ruo 58% nke mbụ bauxite ruo 84% ruo 88%.
