The only other experience I had was refining a gold complex that assayed only 1/10 of your ore. The ore was primarily quartz, with streaks of iron pyrite, silver, gold and galena. The ore was crushed fine in a ball mill, then run with cyanide and bromine. Extraction was well over 99%, even without eliminating the sulfides.
My process used to be pan down the crushed ore (-20 mesh + -), roast it to powder, then separate the iron with a magnet...
