In the course of extracting carbon from quartz we have, on multiple occasions, observed concentrations of in situ 14 C that were anomalously high and in excess of geologically plausible maximum concentrations. We hypothesise that the elevated in situ 14 C concentrations are sourced from part of the widely used mineral separation procedure known as froth flotation, a process that relies on ...
