refractory grade size 1-3mm calcined bauxite
1. Calcined Bauxite 1-3mm brief introduction:
Calcined bauxite is a mixture of minerals that contain various concentrations of hydrated
aluminum oxides as well as impurities. The primary ore minerals are gibbsite (alumina tri-hydrate), boehmite and diaspore (alumina monohydrates).
