The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements. This …
Besides bioleaching using Acidithiobacillus bacteria and bioremediation using SRB, many mining organisms which inhabit ore deposits find applications in mineral beneficiation such as microbially induced flotation and flocculation.Acidithiobacillus spp can be used also to bring about microbially induced flotation and flocculation of minerals. . Heterotrophic …

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and …
This chapter provides an overview of various innovation and technology developments in mineral processing that have shaped the current gold and silver industry. A glimpse of the present and future challenges in mining is also presented. A holistic approach to problem...
The efficiency of physical separation techniques of heavy minerals usually encounters some set-backs. The reason is often not far from the inability to develop suitable mineral characterization strategies in order to comprehend/evaluate certain physicochemical features such as surface chemistry, specific gravity difference, …
Mineral beneficiation at present takes place largely in countries that have no mineral endowment (Baxter, 2005, p. 25). Mineral beneficiation is defined as the process in which mineral products are transformed through different processes and by adding other inputs (Baissac, et al., 2015, p. 10). Thus, mineral beneficiation, refers to the
