Challenge MMI 01
Reduction of Iron in the Production Process of Nepheline Syenite Concentrate

The nepheline syenite mineral is processed in a concentrate factory and its iron is reduced.
Iron is considered as a pollutant and reducing its amount leads to an increase in the added value of the final product.

In this way, we have reached operational technologies to reduce the grade of iron and other pollutants.
Our challenge is to achieve the executive method in the factory in reducing the grade to 0.05 percentage is technically and economically justified.

The Challenge:

New operational technology, reduction of iron grade to 0.05%, constant oxide content.
