In practical appliions, there is a very important problem of the gangue grading, so need to study how particle size of gangue to effect mechanical properties of gangue. First, rock samples were graded according to ...
DIRECT FROM
Ore chemistry and oxide mechanical properties both influence yield through to liquid steel. An ore with the optimum chemis try may not have the optimum mechanical properties for producing DRI. The ore that leads to maximum yield likely will be a compromise of oxide pellet chemical and mechanical properties. Lump ore also can be reduced in gasbased direct reduction shaft furnaces, but the ...
