Innovative Development on Agglomeration of Iron Ore Fines ...
lump ore preparation (10–30 mm size) lots of mineral dressing (crushing, grinding, screening etc.) are required wherein a significant amount of fines (~ 60%) are gener-ated. These fines cannot be used directly in any furnaces. For utilization of these fines, agglomeration techniques, such as sintering, pelletizing, or briquetting, are required.

US6632258B1 - Coal beneficiation by gas agglomeration ...
Coal beneficiation is achieved by suspending coal fines in a colloidal suspension of microscopic gas bubbles in water under atmospheric conditions to form small agglomerates of the fines adhered by the gas bubbles. The agglomerates are separated, recovered and resuspended in water. Thereafter, the pressure on the suspension is increased above atmospheric to deagglomerate, since the gas bubbles ...

Iron Ore Agglomeration Technologies | IntechOpen
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...

Agglomeration Drums in the Heap Leaching Process
Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time.. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.
