Application of glucolipid bola-amphiboles biosurfactant in mineral processing
Dhar, Priyanka; Chernyshova, Irina; Thornhill, Maria; Roelants, Sophie; Soetaert, Wim; Kota, Hanumantha Rao (Chapter, 2021)Yeast-derived amphiboles have attracted considerable attention for their applications in various industrial sectors. However, only a few studies on this class of surfactant have been reported to be relevant to mineral ... -
Green foam-based methods of mineral and ion separation
Jain, Garima; Havskjold, Håkon; Dhar, Priyanka; Ertesvåg, Helga; Chernyshova, Irina; Kota, Hanumantha Rao (Chapter, 2020)We discuss an important gap in the literature on progress toward the development of green (microbial-derived) reagents in conventional (froth flotation) and emerging (foam flotation)separation methods. For comparison, we ... -
Investigation of Copper Recovery from a New Copper Deposit (Nussir) in Northern-Norway: Thionocarbamates and Xanthate-Thionocarbamate Blend as Collectors
Dhar, Priyanka; Thornhill, Maria; Kota, Hanumantha Rao (Journal article; Peer reviewed, 2019)Norway has newly seen an upsurge of interest in exploiting its mineral deposits influenced by fresh Government focus and survey support for previously under-prospected areas. One of the major areas of interest is a huge ... -
Investigation of Copper Recovery from a New Copper Ore Deposit (Nussir) in Northern Norway: Dithiophosphates and Xanthate-Dithiophosphate Blend as Collectors
Dhar, Priyanka; Thornhill, Maria; Kota, Hanumantha Rao (Journal article; Peer reviewed, 2019)he Norwegian mining industry is currently showing increasing interest in the production of metals. Recent research has demonstrated promising results identifying the high potential of the Nussir deposit for the production ... -

An overview of calcite recovery by flotation
Dhar, Priyanka; Thornhill, Maria; Kota, Hanumantha Rao (Peer reviewed; Journal article, 2020)In general, precipitated calcium carbonate (PCC) is used as amineral filler in paper industries; while natural calcite (CaCO3) ore is also suitable for industrial use if it is a finely ground high-grade material. Naturally, ... -
Toward Green Flotation: Interaction of a Sophorolipid Biosurfactant with a Copper Sulfide
Dhar, Priyanka; Havskjold, Håkon; Thornhill, Maria; Roelants, Sophie; Soetaert, Wim; Kota, Hanumantha Rao; Chernyshova, Irina (Peer reviewed; Journal article, 2020)The United Nations’ Sustainable Development Goals have sparked growing interest in biosurfactants from many surfactant-loaded industries including those utilizing froth flotation for mineral separation. However, the ...
