Our iron ore wet processing plants are proven to successfully deal with silica and alumina contamination in the iron ore, resulting in an increase in the Fe value of the iron ore thereby increasing the efficiency of the steel production process.
Silica requires very high temperatures in the kiln, therefore, increasing energy costs when it is present in the feed to the kilns. Both alumina and silica build up in the kilns as a coating, reducing the efficiency of the kilns over time.
This requires that the kilns be shut down in order to facilitate the removal of this material build up. Our iron ore processing plants target these contaminants and ensure their effective removal from the feed to the kilns. This has the effect of increasing the Fe value of the iron ore allowing for a more efficient steel production process.
