    There has been considerable recent interest in the possibility that the plasma membrane contains lipid rafts, microdomains enriched in cholesterol and sphingolipids. It has been suggested that such rafts could play an important role in many cellular processes including signal transduction, membrane trafficking, cytoskeletal organization, and pathogen entry.

Although chalcopyrite recovery and grade are generally high in the flotation of most copper and molybdenum ores, this is not the case for molybdenite, whose flotation is much lower and sensitive to changes in hydrodynamic and pulp conditions in the flotation cell [9,10,11,12].

    Cupellation is a refining process in metallurgy where ores or alloyed metals are treated under very high temperatures and have controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore. The process is based on the principle that precious metals do not oxidise or react chemically, unlike the
