With the rapid development of iron metallurgical industry, it
has caused a huge amount of iron ore slag. Dumping or
disposal of such great quantities of tailing occupies a large
amount of land and causes damage to the ecological environment, which has determined that iron ore slag should look for
technologica ldevelopment to ensure their viability in the short
and long term.The iron ore slag contains iron, silica, alumina,
calcium oxide etc., indicating that it is a valuable resource for
recycling and utilizing.
