Page 1 of 2 Concentration BANDUNG Grassberg uranium mining area of PT Freeport Indonesia's West Papua is judged not significant enough so as not economically feasible to be developed.Geological Society Chairman of the Indonesian Economy (MGEI) Sukmandaru Prihatmoko said scientific research efforts on the content of uranium in West Papua has been done, either by Freeport as well as independent scholars in the field of geology. Based on these studies, he said, has not so far found that it contains significant uranium in West Papua. "Data highest levels of uranium found in a prospect area Freeport is 83 parts per million [ppm]. The figure is far from the minimum value is economical to mine uranium in the world today amounted to 1,000 ppm, "explained Sukmandaru in a press release, today. Sukmandaru also said that just as in other metal minerals namely copper, silver, gold, etc., requires enrichment of natural uranium up to a certain level to be mined economically. The geology, he said, both within the island of Papua in Indonesia and Papua New Hemisphere New Guinea formed by the collision between the Australian Plate and the Pacific on the edge of magma that produced the collision. This process is then formed a line of copper and gold mineralization in several places. In terms of geological exploration, the brightness, the deposit-deposit copper-gold mineralization at this point are generally classified as a type of porphyry copper-gold deposits and epithermal gold. "The results of research and exploration around the world so far shown no significant uranium content in line with the type of mineralization in porphyry copper-gold and epithermal gold such as those in Papua," he said By: Rudi Ariffianto (Bisnis.com)
