grinding energy efficiency using three stages of magnetic separation, traditional autogenous. offer significant financial advantage for competent magnetite ores requiring fine grinding. Figure 3.
Many banded iron formation deposits are very fine grained, often requiring a final concentrate grind size P80 of 25-35 μm (see liberation curve of magnetite in Figure 2). The amount of energy required to produce a magnetite product suitable for sale as pellet plant feed from these deposits is an order of magnitude higher than an equivalent direct shipping lump (< 32 mm > 6 mm) and fines (< 6 mm)

magnetite ores requiring fine grinding. grinding energy consumption is affected by both comminution and in this drive for improved energy efficiency the role of classification has
Abstract. Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes.This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget.
fine grinding energy efficiency magnetite. Conversely, fine-grained magnetite ores require fine grinding, often to below 30 μm, to liberate the magnetite from the silica matrix, incurring greater costs and energy consumption. The comminution energy consumption could be over 30 kWh/t, an order of magnitude higher than for hematite ores.

ultra fine grinding mill in the pharmaceutical and pigment industries, application is the potential for IsaMills™ to be part of magnetite flow sheets, which are being considered in Australia to meet the growing iron demand of Comparing energy efficiency in grinding mills, in
2012. 7. 1.· 2.2. Fine grinding and magnetic separation. Two kinds of mills, a vertical stirred mill and a ball mill, were used to compare the liberation effect of the fine ground magnetite. The vertical stirred mill was a laboratory pin stirred mill. A six-pin stirrer was attached to the gearbox and had a variable speed.
As fine grinding is typically used on regrind applications, the feed tonnages to fine grinding circuits are small compared to head tonnages, typically 10 to 30 tph. However, the specific energies are often much larger than those encountered in intermediate milling and can be as high as 60 kWh/t.
2015. 1. 1.· Conversely, fine-grained magnetite ores require fine grinding, often to below 30 μm, to liberate the magnetite from the silica matrix, incurring greater costs and energy consumption. The comminution energy consumption could be over 30 kWh/t, an
2017. 12. 21.· The Levin test for fine ball mill product predicts a net specific energy requirement of 52.5 kWh/t to grind from an F 80 of ~400 µm (AG mill/magnetic separator product) to a
