Processing of Magnetite Iron Ores Comparing Grinding

The Coalition for Energy Efficient Comminution the lowest operating cost was achieved by multistage fully autogenous grinding with integrated magnetic separation steps between the stages. The major benefit of fully autogenous grinding is the elimination of steel grinding media costs and the need to discriminate between steel and magnetite

Reducing Grinding Energy and Cost Magnetite Iron Ore

Efficiency of the comminution operations is traditionally assessed based on operating cost and energy consumption. Traditionally, the lowest operating cost was achieved by multi-stage fully autogenous grinding due to elimination of steel grinding media costs which may represent up to 50% of the grinding

TowerMill circuit performance in the magnetite grinding

Mar 15, 2019 The grinding efficiency at the finer end (35 µm) for Survey 2 was almost similar to Survey 1, but at 80% passing size the operating work index was 16% lesser indicating more efficient grinding due to coarser feed. The circulating load increases from 129 to 134% with coarser feed.

How energy efficient is HPGR?

Sustainability drivers such as energy efficiency are soon to play a very important role in a mine’s triple bottom line, and as such innovative ways of improving overall energy efficiency such as the application of High Pressure Grinding Rolls (HPGR) is now being pursued.’ The world is rapidly becoming more ‘green’ i.e. energy conscious.
