Coal beneficiation is one of the most effective methods for removing minerals (such as gangues and pyrite) and pollutants (such as sulfur) before the burning of coal. In general, the beneficiation process of low rank coals is more difficult to achieve than that of bituminous and/or anthracite coals. However, about 50% of the world's total coal deposits are low rank coals

A process was developed for the beneficiation of a low-rank coal containing relatively high ash (25.97%) and sulphur (5.78%) content. The low-rank sub-bituminous coal of Makerwal Area, Surghar Range, Punjab Province, Pakistan was cleaned by froth flotation technology to get high quality clean coal for commercial applications

The utilization of laterite sulfuric acid leach residue has always been a challenge in the metallurgical industry. The current treatment involves deep-sea landfills, which leads to considerable environmental pollution and resource wastage. In this work, an effective method is proposed to recover iron and chromium from sulfuric acid leach residue. The effects of roasting temperature, reducing

Apr 11, 2019 The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of iron and steel industry. The depletion of high grade iron ore resources make it inevitable to utilize the existing low grade iron ores/fines/tailings with effective beneficiation to meet the present specification and demand. Enormous amounts of fines are produced both from the natural

Aug 25, 2018 In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than others. The combination of spiral and multi gravity methods
