WebAlteration via near surface oxidation of the valuable base metal sulfides and platinum group minerals resulted in lower flotation recoveries of Cu, Ni, Pt, Pd. Evidence of incipient oxidation was more readily observed in the base metal sulfide assemblage than the platinum group mineral assemblage, even though the loss in recovery because of oxidation was … WebSilica (SiO2) content also controls the minerals that crystallise and is used to further classify igneous rocks as follows: Acid: rocks with above 63% silica (mostly feldspar minerals and quartz), e.g. granite. Basic: rocks that are about 45 to 55% silica (mostly mafic minerals plus plagioclase feldspar and/or feldspathoid minerals), e.g. basalt. WebOrthopyroxene is the most characteristic and important ferromagnesian mineral of the rocks of the charnockite series and is a typical mineral of the granulite facies of regional metamorphism.
