how to reduce silica in bauxite 2

How can you separate alumina from silica in bauxite ore .

How can you separate alumina from silica in bauxite ore .

To separate alumina from silica in bauxite ore associated with silica, first the powdered ore is digested with a concentrated NaOH solution at 473 - 523 K and 35 - 36 bar pressure. This results in the leaching out of alumina (Al 2 O 3) as sodium aluminate and silica (SiO 2.

Implementation of reverse flotation method to reduce .

Implementation of reverse flotation method to reduce .

This paper reports a study that implements reverse flotation method to separate silica from West Kalimantan bauxite ores. The study is aimed to find the good process condition to obtain low-silica bauxite as the feed for the Bayer process. The experiments were carried out in a 1 L of flotation cell tank. Dodecylamine was used as the collector, starch as the depressant, and MIBC as the frother.
