چکیده

Abstract The main indicators of the iron ore quality are content iron, silica, phosphorus and other components. It is ascertained that depends on its grain-size composition. article proves when crushing 16-0 mm fraction to 5-0 mm, Fe reclassified by sizes due liberation both martite hematite at this grain size. To reduce energy consumption during grinding, it recommended install high pressure grinding rolls for 16-1 consider operation as first stage grinding. Martite in -1.0+0.0 material shows significant predominance (87.0 vs. 13.0%) free grains over aggregates observed -0.071+0.05 material. Free make 57.12% -0.16+0.071 Complete (100%) -0.05 Sieve analysis A56 sinter sample crushed industrial roll crusher enables ascertaining greatest increase recovery (Fe tot = 60.05%) occurs

The Application of Artificial Neural Networks to Ore Reserve Estimation at Choghart Iron Ore Deposit

Geo-statistical methods for reserve estimation are difficult to use when stationary conditions are not satisfied. Artificial Neural Networks (ANNs) provide an alternative to geo-statistical techniques while considerably reducing the processing time required for development and application. In this paper the ANNs was applied to the Choghart iron ore deposit in Yazd province of Iran. Initially, a...
