The closer' size range and higher strength of raw materials obtained during agglomeration improves the performance of arc furnace to a great extent. Further the ore feed is partly reduced outside the arc furnace, so that the power requirement in the arc furnace is much lower and overall economics of the operation is improved. 2.0 PELLETISING
percolation within the heap, low heap strength and low recovery rate. Agglomeration of laterite ores has the potential to overcome these difficulties. Agglomeration is basically the process of adjusting the size distribution of the material placed on a heap. In wet agglomeration, as used in heap leaching, the particles
Based on the extensive experience of heap leaching operations, crushed ore agglomeration can be successfully considered and utilized as a pretreatment step for the heap …
