If documentation states cargo is iron ore fines the Master may interpret cargo as fines from iron ore, a Group "C"cargo. Knowledge of section 7.2.1 of the Code is required. This states that cargoes with a certain amount of moisture and small particles may liquefy.
Beneficiation of low-grade iron ore fines by multi-gravity separator (MGS) using optimization studies. ... There is an urgent need for development of environmental friendly processes through which iron ore fines can be beneficiated and utilized effectively. For processing of low-grade iron ores, ground to finer size necessitates the use of ...
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke).
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 …
