Developments in iron ore comminution and

2015-1-1 · Future trends in iron ore comminution and classification The in situ grade of magnetite ores is much lower (~ 20–50% Fe) compared with hematite/goethite ores. Therefore, magnetite ores will always require crushing and grinding followed by magnetic separation and, in some cases, reverse flotation to produce high-grade concentrates suitable for pelletizing.

- Test methods for characterizing ore comminution

2016-10-19 · Comminution is usually the first stage in mineral processing plants. Normally the comminution circuit includes several stages starting with crushing and followed by grinding (Figure 1). Primary crushing is often done close to the mining area, e.g. underground or in the pit. Depending on the ore and process types there can be several

Development of a Novel Grinding Process to Iron Ore ...

The earliest industrial application of high pressure grinding rolls (HPGR) at comminution was in 1984 in the cement industry. Since then, the equipment has been widely applied in mining activities. Despite the rapid spread across the industry, several challenges are still present in the equipment’s application, especially considering the complex ore breakage behaviour reported for this process.
