Manganese fines. With their high manganese content, our fines have been developed for the production of silicomanganese (SiMn). This ore is used to improve process performance (less waste, reduced energy consumption), particularly in the production of agglomerates. Its low iron content makes it highly complementary to iron rich ores.
