June 25, Colombo: Sri Lanka Geological and Mines Bureau says that recent studies carried out island wide have shown that ores containing gold are present in the island.
The Chairman of the Bureau Dr. N.K. Wijayananda told media that gold ore could be found in Balangoda, Kirinnabara areas and the areas close to Walawe and Menik Rivers.
The Chairman said that many countries use physical and chemical methodology to process gold ore.
However, Sri Lanka Geological and Mines Bureau will never permit chemical processing of gold ore, the Chairman says. The exploration to find gold ore was slow and costlier due to the use of mechanical process, he said.
Gold extraction or recovery from its ores may require a combination of comminution, mineral processing, hydrometallurgical and pyrometallurgical processes to be performed on the ore.
