- Prerequisite In Ore Dressing Process
The blast furnace and direct reduction processes have been the major iron production routes for various iron ores (i.e. goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous. The challenges, such as cumbersome production …

For low-grade iron ore dressing, the SS in process waters are highly dispersed during separation processes and difficult to completely remove—and this issue becomes serious with SS accumulation through process water reuse (Wang et al., 2019; Yenial and Bulut, 2017). SS removal from this process water form therefore needs more …

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.
