The following remarks on the use of the fire assay fluxes and litharge may serve as an aid in arriving to a correct composition of charges for most cases:.

It can be depending on, like stated, the concentrations of it in the host rock, quartz. Gpx's are not the greatest for fine gold species though the later 5000 then 6000 do a much better job than the previous ones, especially the 5000 with a small evolution coil or the 6000.

It's universally considered the richest of the gold ores out there.
