Quartz veins often fluctuate widely in value with the richest gold ore occurring in pockets or “bonanzas” as they are sometimes called In some mining districts the bulk of the gold is found in these rich pockets and the rest of the vein may be nearly barren

We want pure gold but goldbearing rocks include lots of other materials such as quartz calcite and the sulfides of other metals We need to separate the gold from everything else in the rock so the rock needs to be treated in some way In New Zealand we chiselled some rocks from an outcrop near a small creek

A wet chemical process was developed for the separation of gold from goldbearing antimony sulphide ores The ore sample was taken from the mine Urquidi from Oruro in Bolivia It contained roughly 33 Sb in the form of antimonite 24 Si in the form of quartz small quantities of Pb Fe Cu and Ni as well as 63 gt gold 60 of it as visible gold
