Minerals from residues.


Minerals from residues are often not stable and due the essence of leaking metals, acid or alkaline not suitable for re-use.


This is common with;

-                steel slag

-                Fly ash

-                Red mud

-                Oil Shale residue



These residue contain often minerals like Mg and Ca silicates and oxides, which can react wit CO2. 

At atmospheric level, these minerals react with CO2, but because of the reaction layer, this iss only a minimum reaction.

The core of the grain is still unstable, so the leaching still goes on.


The GPV process is totally different and a much more stable residue shall be the result.

Using the GPV technique, it’s possible to bind CO2 and get stable residues.


The kind of process is used and the reaction parameters of the process, depends on the kind of residues.

For further information, we apply  at the kind off residue.


Innovation Concepts B.V. from the Netherlands has a different patent pending due the GPV technique, reacting CO2 or other acid with residues in order to bind CO2 and stable the residue.


During the year 2011,  several tests will be profiled.

Innovation Concepts B.V. designed a special autoclave, which simulate the GPV process on Lab scale.
