Gold Bearing Quartz. High Quality Mineral Specimens

Gold bearing quartz is one of the most rare types of natural gold that you can collect. The vast majority of gold mined today is produced by blasting and crushing ores to extract the gold. Very few large scale mining operations retain the larger collectable pieces that they produce.

Gold ores are classified "freemilling" and "refractory" based on their response to cyanide dissolution. Bioprocessing can be used to treat refractory goldbearing sulfide ores as well as carbonaceous gold ores. It is essential to characterize different types of gold ores to understand the extent and nature of goldentrapment in different associated mineral phases before an appropriate ...
