The Direct Reduction of Iron Thomas Battle James McClelland in Treatise on Process Metallurgy Industrial Processes 2014 Agglomeration of Iron Ore The three major forms of iron used in ironmaking are pellets lump and sinter The major change in the past 50 years has been the development of cost effective pelletization technology allowing pellets to be a
The eastern region itself accounts for the 55% of the total Iron ore of our country The share of lumps in total iron ore production has been about 40 % with the rest being accounted for fines and concentrates Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the feed
In the early developmental stages of iron ore beneficiation relatively coarse grinding was used and the Blaines of the concentrates usually ranged from 1300 to 1600 cm²/gram Although drum filters were briefly used for early dewatering in order to compete with direct shipping ores capital operating costs were reduced by employing the disc
The industrial test results of this magnetic separator reveal that the iron grade improved by percentage points and that the recovery rate reached % after primary sorting using <1 mm KBH dephosphorized ore from South Africa Then the iron grade was improved by percentage points and the recovery rate reached % after sorting
