metalliferous ore an overview sciencedirect topics,crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 1020 cm in heavy-duty machines. in most operations, the primary crushing schedule is the same as the mining schedule..mining quarrying mineral and ore processing coal iron,mining, quarrying, mineral and ore processing, coal, iron ore, limestone, chromite and granite mining projects india is home to a myriad of metals and minerals. globally, the country is the largest producer of sheet mica, the third largest producer of coal, the fourth largest producer of iron ore and the fifth largest producer of bauxite..
of the processed ore shipped to the iron and steel industry is in the form of pellets. other forms of processed ore include sinter and briquettes. the average iron content of pellets is 63 percent. 11.23.2 process description2-5,41 processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles,
coal is very friable (breaks easily) so you do not need the force a cone crusher can supply. also a cone will create more fines than a roll crusher. another factor being that both roll crushers and impactors take up less height than a cone so the overall height can be less.
