the present chapter focuses on aspects that differentiate processing schemes for gold ores and concentrates with high-silver grades. silver leaching chemistry is reviewed considering specific characteristics of silver mineralogy and its effects on gold extraction.
this step goes faster if you only do small amounts of concentrate at a time. pour the gold recovered in this step into the gold sample bottle. step 6: take the fine concentrates which passed through the final screening and spread them out over a clean sheet of paper. use a magnet to separate the magnetic black sands from these final concentrates.

concentrate is produced from ground-up ore to which mercury is added. only about one gram of mercury is required to extract one gram of gold. however, tailings from this process are often repeatedly run through the ball mills. each time more auriferous, or gold-laden, mercury flour is produced. though less mercury escapes by this method,
such ores are referred to as refractory, and they frequently contain the sulfide minerals pyrite, pyrrhotite, or arsenopyrite. gold can be freed from these ores or concentrates by treating them with various oxidizing processes. the most common method is to roast gold-bearing minerals at temperatures of 450 to 750 c 840 to 1,380 f to destroy the interfering sulfides.
