Anti-mining advocates should jump with joy at the success of a Finnish firm called Talvivaara Mining Co. Plc. that experimented in 2005 on the use of air, water, and bacteria to recover metals imbedded in low-grade ores with nickel and zinc, copper, and cobalt from its mine in Sotkamo, Finland. | |||
This process holds promise for such operations as the Tampakan Copper-Gold Project of Sagittarius Mines Inc. (SMI) in South Cotabato and other mining ventures nationwide since it eliminates the use of substances perceived to be harmful to the environment. | |||
Since the soil-based bacteria gobble up the ore, what remains are the metals that can be recovered quickly, the developers of the technology said. | |||
Under the Talvivaara system, the ore is extracted, crushed, and stacked inside of a heap pad, bacteria are sprinkled onto the ore, and low-pressure fans are used to supply the bacteria with air from outside. Water is then sprinkled to ensure the bacteria would wash into the ore. | |||
As bacteria gobbles up the ore, the chemical wastes they release liquefy the remaining metal, and the solution is then collected in a pond outside the heap and sent to a plant where the metals are recovered. | |||
The solution is recycled and applied to the heap to allow the bacteria to consume the ore anew. | |||
“The Talvivaara polymetallic deposits, Kuusilampi and Kolmisoppi, comprise one of the largest known sulphide nickel resources in Europe with 1.121 billion tons of ore in measured and indicated categories, sufficient to support an anticipated production for several decades. Production at the mine started in October 2008 with the precipitation of the first metal sulphides,“ the company said. | |||
