Improving the activity of Iron Ore Tailings (IOTs) to utilize them as a mineral admixture in cement-based 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. The effect of wet grinding on the activation of IOTs was evaluated through ion leaching from an
Comparison of dry and wet grinding process in an electromagnetic mill is presented in this paper. The research was conducted in a batch copper ore grinding. Batch mode allows for precise parametrization and constant repetitive conditions of the experiments. The following key aspects were tested: processing time, feed size, size of the grinding media, mass of the material and graining media
2017-5-25 The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry
2015-1-1 Iron ore grinding and classification. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits are much finer-grained and therefore require significant grinding to liberate the magnetite from its silicate matrix. Various magnetite ore grinding flowsheets have been implemented in the past, including
