The main reason for the brown colour is due to impurities from Iron and Manganese. As to how much impurity without testing it you can't tell by looking and it's disappointing that we are not given specifics by this amateur Management! It is frustrating to get what could amount to a great announcement, mediocre and little detail in their presentations. The good thing is that to be able to name it MgO the majority of the compound is MgO! How much of it is MgO?
HEY MANAGEMENT how about putting us all in the know? Or are you ashamed of your results? Disgusting behaviour I have to say. What grade MgO did you produce? is it really MgO or is it Fe2O3 with MgO impurity? Sick and tired of you guys acting like Disallowed Salesmen! If you want people to fund your projects into the future, you need to develop some trust with all stakeholders.
