Gold Ore an overview ScienceDirect Topics

Mining requires a large amount of water for floatation, heap leaching of copper and gold ores, dust suppression, equipment cooling, slurry transport, and human needs at the mining sites [46]. However, mining sites are often far from the water sources and it is not easy to secure the water supply. Therefore, the contamination of water that occurs during the processing requires treatment before

What is Gold Ore worth? High Grade Mining Ore

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 sample worth approximately 75 cents, and this is assuming that the ore is extremely rich

Fissure veins often fluctuate greatly in value, so that the ore richest in gold occurs in pockets, or "bonanzas" as the miner says. In some mining belts one may by systematic drifting along the direction of the main fissure vein encounter a gold ore "bonanza." Where the normal concentration or value through the vein might be less than a quarter ounce of gold per ton of ore, a pocket might be
