Enwere ike kewaa ihe nzacha Diatomite n'ime ngwaahịa algae kpọrọ nkụ, ngwaahịa calcined na ngwaahịa calcined flux dịka usoro mmepụta dị iche iche si dị.

① Ngwaahịa akpọnwụrụ akpọnwụ
Mgbe e sachara ya, kpọchaa ya tupu e kpoo ya ma kpụchaa ya, a na-akpọ nkụ ihe ndị e ji esi nri na okpomọkụ 600-800 Celsius, wee kpụchaa ya. Ụdị ngwaahịa a nwere obere nha ma dịkwa mma maka nzacha nke ọma. A na-ejikarị ya na ihe ndị ọzọ e ji esi nri eme ihe. Ngwaahịa ndị a kpọrọ nkụ na-abụkarị odo odo dị nro, kamakwa ha na-acha ọcha na isi awọ dị nro.

② Ngwaahịa ndị e ji calcined mee
A na-etinye diatomite a sachara, kpọrọ nkụ ma gwerie egweri n'ime ọkụ na-agbanwe agbanwe, nke a na-etinye na 800-1200 Celsius, wee gwerie ya ma tinye ya n'ọkwa iji nweta ngwaahịa a gbanyere agwere agwere. Ma e jiri ya tụnyere ngwaahịa kpọrọ nkụ, ikike nke ngwaahịa a gbanyere agwere agwere karịrị okpukpu atọ. Ngwaahịa a gbanyere agwere agwere na-acha ọbara ọbara.

③ Ngwaahịa ndị a na-etinye na calcined
Mgbe e sachara ya, kpọọ ya nkụ ma gwerie ya, a na-agbakwunye obere sodium carbonate, sodium chloride na AIDS ndị ọzọ na-agbaze agbaze nke diatomite, a na-etinyekwa ya na 900 ~ 1200 Celsius. Mgbe e gwerie ya ma hazie nha ihe ndị ahụ, a na-enweta ngwaahịa flux calcined. O doro anya na ọ na-amụba ikike nke ngwaahịa flux calcined, nke karịrị ugboro 20 nke ngwaahịa akọrọ. Ngwaahịa flux calcined na-abụkarị ọcha, na-achakwa pink dị nro mgbe ọdịnaya Fe2O3 dị elu ma ọ bụ obere ego flux.
