Sep 02, 2011 · This can be an indior of gold. Iron Staining Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indiors.
Quartz: is the main mineral of this association. The grain size ranges from to millimetres with the millimetre grain size being the most prevalent.

Gravity concentration tends to recover the pyrite with the gold, and only removes the lighter minerals, such as quartz, from the ore. The most difficult particles to gravity concentrate are the fines, and 75 microns to 2 microns are definitely very fine. So, even if the ore were ground to 2 microns, it may not be recoverable using current ...
Answer (1 of 12): No they do not. Quartz is common, gold is rare. Quartz veins typically form when very hot water rising from depth flows into a shallow crack in the rock. The dissolved silica precipitates as quartz. If there is gold present in the water, it will also precipitate. The result is ...
