[00062136]鈦渣加工方法
技術詳細介紹
項目簡介：
ABSTRACT
FIELD: metallurgy.
SUBSTANCE: proposed method comprises mixing of initial titanium-bearing slag with soda ash, mix sintering and leaching of produced cake, first, in water for production of iron-titanium-bearing precipitate and, then, in muriate for production of titanium-bearing precipitate. Then, pulp is filtered to separate the precipitate to get titanium dioxide concentrate. note here that initial slag sintering with soda ash occurs at 900 °C and Na2CO3:slag ratio equal to (0,98…1,15):1. Cake sintering in water is conducted to transfer sodium silicate to solution while titanium dioxide concentrate is made by calcination of precipitate resulted from hydrochlorideacid treatment. Note here that said initial titanium slag represents that of reducing fusion of ilmenite.
EFFECT: simplified process, higher pulp filtration rate.
