Biotite tests
WebMar 1, 2024 · Biotite (sensu lato) is a widespread silicate hydrous mineral in various geological conditions with potential petrological and geochemical implications. However, due to the chemical and structural complexities of biotite, calculating biotite formula from routine EPMA data has been a challenging task for decades. WebAdsorption tests by measuring the residual surface tension of mineral suspensions indicated that phlogopite and biotite could adsorb EDA on their surfaces, much higher than quartz. Zeta potential measurements confirmed a higher affinity of micaceous minerals to EDA at higher concentrations, matching with micro–flotation and adsorption test ...
