10.1.4 Recovery of Phosphate from Phosphatic Wastes. In the beneficiation of phosphate ores the tailings generated still carry significant phosphate content. The recovery has been difficult as the tailings carry a large proportion of clay minerals, magnesium oxide and iron carbonate mineral known as ankerite, an iron carbonate.
Total iron recovery can be increased without additional grinding and large financial costs. Opportunities in this area are defined by the process equipment. As already noted, the first stage will be fine grain separation from a large quantity of tailings. Ore processing employs screening as the main classification method [1,2,3,4,5,6]. It ...

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.
Abstract. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of organic carbon can also increase the value of the bauxite product.
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
