Diagnostic leaching and Gold deportment
Gold may occur in one to three forms in an ore or mill product: microscopic gold, submicroscopic gold and surface-bound gold, and we need to use different techniques to characterize/quantify different forms of gold. Compared to any other single technique, the advantage of using such a comprehensive approach is that a large sample will be ...

What is Gold Ore worth? High Grade Mining Ore
For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let's assume that gold is valued at $1500 per ...

Roasting and Refractory Gold Ore
During roasting, refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize, separate from the ore, and become sulfur dioxide. Once all of the sulfides are oxidized, the remaining gold ore can be processed normally. The roasting method has been around for hundreds of years.
