As a bulk solid waste with high alkalinity, red mud (RM) not only occupies a large amount of
land and requires high maintenance costs, but also unavoidably generates serious hazards …

The beneficiation of low-grade iron ores to meet the growing demand for iron and steel is an
important research topic. However, certain ores do not qualify to be treated in physical …

Considering the decreasing reserves of high-grade iron ores, the utilization of low-grade
iron ores is of great significance to the steel industry; however, improving iron recovery from …

In order to reduce cost of biodiesel production there is need to use non-edible oil. Kusum
feed oil is non-edible oil, low cost and substantial available for biodiesel production. To …

Abstract The Bayan Obo low-grade polymetallic ore (BOLPO) is a complex polymetallic
resource that has accumulated over decades. Conventional mineral processing struggles to …

As higher-grade ores become depleted, there will be a greater focus on developing suitable
beneficiation strategies to treat low-grade hematite-goethite ores containing higher levels of …

In this paper, a process of pre-oxidation and magnetization roasting followed by low-
intensity magnetic separation and acid leaching (OMLA) was developed to separate and …

Microwave-assisted reduction roasting of a goethite-rich, reject iron ore waste stream (− 2
mm) was used to produce a high-grade concentrate. Reduction roast experiments were …

Currently, the sulfate method used for roasting lepidolite to extract lithium presents several
issues, including high energy consumption and low recovery efficiency. To address these …

In this paper, factors affecting the microwave drying characteristics of rutile TiO 2 were
discussed, and the data were fitted with nine common thin layers drying kinetic models. The …
