The geological block model dimensions are 25 metres by 25 metres by 15 metres high. Due to the size of the equipment utilized for extraction, the smallest mining width practical is approximately 40 metres, however the smallest bucket
Inquire NowHematite is a heavy and relatively hard ferric oxide mineral which crystallizes in a rhombohedral system. The mineral has derived its name from the Greek word for blood as it often observed in red powdered form. Hematite has the same crystal structure as that of corundum and ilmenite.
