Ore characterisation for––and simulation

01-01-2003  In this work, the purpose was to study the impact of variations in feed ore properties on the performance of a primary autogenous grinding circuit by ore characterisation and simulation. Samples were selected to represent various points in the production system; ore faces with different drillability, grinding circuit feed, mill charges and waste rock.

Optimisation of autogenous grinding - ScienceDirect

01-11-2000  Batch tests in a 0.6m diameter mill were used to simulate fully autogenous primary and secondary grinding. Substantial improvements in primary mill capacity were obtained by modifying the mill contents to simulate crushing of small pebbles and recycle of the crushed material. Secondary grinding efficiency (as measured by kWh per ton finer than 75 microns or Work Index), was improved

Primary Secondary AG Autogenous Grinding

Primary autogenous mill feed is either primary crusher discharge or run of mine ore, containing material on each size of the screen analysis below the largest piece in the feed. It is subject to the large variations in size analysis normally found in primary crusher products or run of mine ore. There can also be variations due to segregation in stock pile or bin storage. In feeding primary ...
