Autogenous Grinding Mining Fundamentals

Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or porcelain balls are used as media.

Processing Citic Pacific Mining

Every 24 hours, around 180,000 tonnes of ore are fed into the six milling lines’ autogenous grinding mills (AG mills), these are the largest grinding mills in the world. Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart.

AUTOGENOUS MILL FEED PREPARATION TO REDUCE UNIT

Compared with SAG mill grinding, autogenous grinding using feed prepared to include coarse, competent rock and crushed finer rock resulted in a 14% reduction in grinding energy expressed as kWh/t and no steel balls were required as additional grinding media. The coarse rock amounted to about 20% of the mill feed.

Small-Scale Continuous SAG Testing Using the Macpherson

for the analysis of both fully-autogenous (FAG) and semi-autogenous (SAG) circuits (the fine feed size to the mill would not generate sufficient impact energy in FAG mode). In this paper, for simplicity sake, the term autogenous grinding refers to both FAG and SAG grinding. In the last 10 years, smaller-scale tests have been developed to further

Autogenous and Semi-Autogenous Mills ScienceDirect

Jan 01, 2016· 9.1. Introduction. Disintegration and size reduction of some ores is possible in tumbling mills without the aid of grinding media. Grinding mills in which comminution takes place without grinding aids are known as autogenous grinding (AG) mills or fully autogenous grinding (FAG) mills. These mills use large lumps of rock as the grinding media.
