ABSTRACT. Nickel is a strategic element whose production and consumption in over a decade has increased to over 39% and 71%, respectively. Generally, due to their complex mineralogy, laterites, the current attractive source of Ni, are subjected to hydrometallurgy and pyrometallurgy techniques without enrichment in order to extract Ni.
Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques …

It is recommended that to ensure future mineral processing, tailings and mine wastes of 3 T minerals should be properly managed. The current extraction methods do not allow the extraction of the total amount of minerals from the ore concentrate. Therefore, the tailings and wastes are still a potential resource and should be managed …
This study investigates the potential application of microwave imaging (MWI) in ore sorting systems for mineral processing. Modern sensor-based ore sorting employs various sensing methods, such as ...
Ore sorting has long been used to raise the efficiency and thus lower the environmental impact of mineral processing operations. It was first instituted as hand sorting, according to a humanly perceived difference in the ore, but is now automated using large mechanical sorters in order to meet the high tonnage throughput required in most minerals …
Although Australia's vast endowment of minerals is unlikely to be exhausted in the foreseeable future, the extraction of many of these minerals has become more challenging over time (Giurco et al., 2009).Declining ore grades are indicative of a shift from the extraction and processing of "easier and cheaper" ore bodies to more "complex and …
