High-grade MgO benefits

As more and more mines are converting to magnesium oxide (MgO) for cobalt precipitation, MOX HQ45 from Protea Mining Chemicals is a naturally pure magnesium oxide from source.


MgO is a preferred option because it provides steady and better controlled pH movement. A pure product means less impurities, therefore purer cobalt hydroxide precipitate. Protea’s MOX HQ45 is extremely reactive, which in turn improves productivity levels and provides an opportunity to reduce retention times.

One of the advantages of MOX HQ45 is that it is able to provide site specific quantifiable benefits, such as savings in drying energy costs. It is widely used in the copperbelt and is gradually replacing conventional bases such as soda ash and lime.
