Impact of Stibnite on gold recovery . Hedley and Tabachnick, in an excellent monograph published by American Cyanamid in 1968, made up a synthetic gold ore using a mixture of very finely divided gold in pure silica (sand) and then added various deleterious minerals at 2500ppm to check their effect on gold dissolution.
