Comminution circuits for compact itabirites - CORE

This work makes a comparison between comminution circuits for compact Itabirites from the Iron Quadrangle. The circuits developed are: a crushing and ball mill circuit (CB), a SAG mill and ball mill circuit (SAB) and a single stage SAG mill circuit (SSSAG). For the SAB circuit, the use of pebble crushing is analyzed (SABC). An industrial circuit for 25 million tons of run of mine was developed ...

Comminution - an overview ScienceDirect Topics

G.W. Heyes, in Iron Ore, 2015. 11.2.2 Liberation. Comminution is needed for the liberation of low-grade ores so that the iron content can be upgraded by gangue removal. This necessitates grinding to such a size that the iron minerals and gangue are present as separate grains. But comminution is an expensive process and economics dictates that a compromise must be made between the cost of ...

Comminution Circuits for Gold Ore Processing - ScienceDirect

01/01/2016  Such a circuit can counteract the effects of harder ore, coarser ore, decrease the size of SAG mill required, or rectify poor throughput due to an undersized SAG circuit. Notably, harder ore often presents itself to the SAG circuit as coarser than softer ore—less comminution is produced in blasting and primary crushing, and therefore the impact on SAG throughput is compounded.

How to use comminution processes for reducing the ore size ...

There are two types of comminution circuits; open and close circuit. In most cases, we use a combination of them to control the ore size at every stage, then to get a final product with narrow size distribution and less fine particles. Moreover, it is a question of energy consumption, engineering, and circuit optimization. For example, suppose we have an iron ore of 0.5
