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 ounce. That would make the gold in a one pound ore

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.

From ore to doré. Cyanidation. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids.
