Nkọwa dị mkpirikpi

A na-emepụta Brown Fused Alumina site na mgbaze nke Calcined Bauxite n'ime ọkụ arc eletrik na okpomọkụ karịrị 2000 Celsius. Usoro siri ike ngwa ngwa na-esochi ngwakọta, iji nye kristal blocky. Enyemaka mgbaze na iwepu sọlfọ na carbon, njikwa siri ike na ọkwa Titania n'oge usoro ngwakọta na-eme ka ike sie ike nke ọka.

Mgbe ahụ, a na-echipịa crude ahụ jụrụ oyi, kpochaa ya site na adịghị ike magnetik na nnukwu ike magnetik separators na nkewa n'ime warara size irighiri ka dabara ọgwụgwụ ojiji. Ahịrị raara onwe ya nye na-emepụta ngwaahịa maka ngwa dị iche iche.
