The comminution of ores consumes a high portion of energy. Therefore, different pretreatment methods of ores prior to their comminution are considered to reduce this energy. However, the results of pretreatment methods and their technological development are scattered in literature. Hence, this paper aims at collating the different ore pretreatment methods with their applications and results ...

Reduce, reuse, and recycle are important techniques for waste management. These become significant for improving environmental and economic condition of industries. Integrated steel industries are generating huge amounts of steel slag as waste through the blast furnace and LinzDonawitz (LD) process. Presently, these wastes are disposed by dumping in an unplanned manner, which causes many ...

Abstract References Citations Supplementary Data Improving the activity of Iron Ore Tailings (IOTs) to utilize them as a mineral admixture in cementbased minerals is still challenging. In this paper, the wet grinding technology was employed to stimulate the activity of IOTs, and the traditional dry grinding method was used as a reference.

of these four materials in dry and wet grinding conditions. It shows that coal and dolomite are easy to grind materials by dry grinding method whereas iron and manganese ores are suitable for wet grinding. It was seen that wet grinding improve the material fineness than dry grinding and maximum 15% improvement in D 80 was seen for iron ore samples.

Iron ores obtained from different sources differ in their chemical and physical properties. These variations make the process of grinding a difficult task. The work carried out in this context focuses on three different samples of iron ore, viz., high silica high alumina, low silica high alumina, and low silica low alumina. The grinding process for all the three iron ores is carried out ...
