What is Smelter Grade Alumina (SGA)?

Smelter grade alumina (SGA) is the main raw material for smelting aluminum ingot, which has the features of light dusting, light weight, high fluidity, high dissolvability, fine solubility, and strong absorption of fluoride. Smelter grade sandy alumina is used for smelting aluminum by molten salt electrolysis.

Main Features of Our Smelter Grade Alumina (SGA)

The smelter grade alumina provided by TechSolutions adopts the advanced Bayer process. The smelter grade sandy alumina refining process integrates the most advanced technology and equipment of bauxite refining alumina in China and international market. The core technology of smelter grade sandy alumina refinery process are pipeline digestion process technology, gas suspension calciners technology, etc.

The refined smelter grade sandy alumina product is in accordance with the requirements of alumina standards, with low content of Fe, Na, zinc, lithium and other impurity elements, with the characteristics of high fluidity, strong adsorption capacity, high strength, high activity, environment friendly, energy saving, light weight, easy to transport and so on.

smelter grade sandy alumina is mainly used for smelting aluminum through aluminum smelters pot technology

Packing: in bulk and in bags (including 1.5 tons and 1.7 tons).

Technical Data

China national nonferrous industry standard YS/T 803-2012 for Smelter grade alumina is shown as follows:

Alumina Standard

YS/T 803-2012 China Nonferrous Metals Industry Standard, Smelter grade alumina
YS/T 274-1998 China Nonferrous Metals Industry Standard, Alumina
GB/T 24487-2009 China National Standard, Alumina
GB/T 6609.1-2018 China National Standard, Chemical analysis methods and determination of physical performance of alumina
Note:
1) The national standard of alumina is only the national standard of the former Soviet Union in 1974 (ΓOCT 6912-74), and there is no alumina product standard formulated by ISO, EN, ASTM and other organizations at present.
2) Other alumina standards are mainly alumina production enterprise standards, such as QAL, ADG, FRIGIA, Worsley, ALCOA, PECHINEY, KAISER, etc.
