I note reference to MgO in today's announcement. Words like "smelters sensitive to MgO" and references to sulphuric acid washes to reduce its concentration, lead me to think that this might be a negative.
Can someone please explain this for a non-techo like me. What is MgO, does its presence present short or long term difficulties to MBN and will it impact on the value of the ore?
Thanks
