Clean Mining announces breakthrough gold ore processing

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. ounces of gold. Now let's assume that gold is valued at $ per ...TCB International is an ore processing facility that extracts the following precious metals: gold, silver, and platinum group metals. Unlike many of our competitors, our chemical process allows us to process black sands, sulfide ores, and the platinum group metals in addition to gold and silver. · Clean Mining Ltd, an Australian technology company, announced the world's first breakthrough technology to eliminate the use of cyanide from gold ore processing at the 3rd Asia Pacific Precious Conference held in Singapore on June 10, .
