Globally the major iron ore producers are Vale, Rio Tinto, BHP Billiton and Fortescue Metals. The prevailing low commodity prices ensure that only the largest and lowest cost producers survive and thus mines in China, Canada and South Africa are buckling under the pressure. From a product demand perspective, Fe ore fines make up approximately 60% of
