In recent years, extraction of zinc from low-grade mining tailings of oxidized zinc has been a matter of discussion. This is a material which can be processed by flotation and acid-leaching methods. Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process.
Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.
bioleaching or bio beneficiation Jain and Sharma, 2004, is another variant of the above mentioned chemical processing. In such a process, the micro organisms produce, as a consequence of their metabolism, a chemical by-product mineral acids, organic acids, polymers, enzymes. The

Description of Study Site and Experimental Cells. To evaluate the feasibility and effectiveness of using alkaline phosphate mine wastes as a store-and-release layer to limit infiltration of water in acidogenic tailing mine, field investigations were conducted at Kettara mine 31 5215N8 1031W.
Froth flotation collectors comprising dithiocarbamates of the Formula I as described herein are useful for the beneficiation and recovery of metals from mineral ores. Novel dithiocarbamate collectors and their use in the benefication of mineral ore bodies
Notably, he was also recognized for implementing Six Sigma projects in a beneficiation plant. Srinivas has obtained a fellowship at the Indian Institute of Mineral Engineers. He is an active member of the Indian Institute of Metals, Kolkata and the Indian Society for Training and Development.
Jul 02, 2012 The bioflotation and bioflocculation processes of relevance to mineral beneficiation have been critically reviewed , . These studies have led to the understanding that the interaction between specific microbial cells and mineral particles brings about significant changes in the chemistry of mineral surfaces, as well as the bacterial surfaces.
by the various mineral industries. Recent progress on these microbial processes in both hydrometallurgy and mineral pro-cessing is reviewed in this paper. In addition, the role of the mechanisms of interactions found in different biological processes is discussed. Biomineral beneficiation can be defined as a beneficiation process brought about by

Recent developments in biotechnology have opened up possibilities for the utilization of microorganisms in mineral beneficiation as flotation collectors, depressants and activators. ... a protein hydrolyzing enzyme and the characteristics of the treated cells were studied.
The use of the terms extraction, beneficiation, and mineral processing in this document is not intended to classify any waste stream for the purposes of regulatory interpretation or application. Rather, these terms are used in the context of common industry terminology.
Bioreactor technology using thermophilic bacteria holds the key for the successful and efficient bioleaching of chalcopyrite, sphalerite and pentlandite concentrates. Microorganisms find use in environmental control and mineral beneficiation as well. Microbially-induced mineral flotation and flocculation have been proved to
The divergent role of microbes in the field of mineral processing starting from mining and beneficiation to efficient waste disposal has been well recognized now. The roles of various microorganisms and bioreagents in the beneficiation of minerals are illustrated in this paper.
Processing of mineral beneficiation is composed of a series of unit operations as illustrated in Figure 1 by a simple example. Raw ore, or run-of-mine ore, is received by the storage 1 of the crushing plant for temporary storage, and then discharged through the
