Product Description

      Good Quality Refractory Materials Bauxite Ore With 60-80% Al2O3

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.

Classification Introduction:

1.Classified according to the type of bauxite raw materials:
   (1) raw bauxite, alumina original ore (natural sedimentary rock class).
   (2) the calcined bauxite, the raw bauxite after high temperature calcination (1200 ~ 1700 ºC)

2.Calssified according to the different calcining kiln where the bauxtie is divided into:
   (1)Shaft kiln bauxite
   (2)Rotary kiln bauxite
   (3)Round kiln bauxite

3.Calcined Bauxite according to different uses for division:
   (1) the refractory grade bauxite
   (2) the grinding grade alumina
   (3) the welding grade bauxite

Bauxite has a lot of different specifications like

 

Granular ( 0-1mm 1-3mm 3-5mm 5-8mm) 
Powder ( 200mesh 325mesh 280mesh, 240mesh, 180mesh, 150mesh, 120mesh, 100mesh )
and big lump , the Al2O3 from 65-90%
we can also produce according to customers special requirement
