Grade Placer Deposits Of Iron Papua New Guinea

Mining in Papua New Guinea - Wikipedia

Increased mining in Papua New Guinea has caused notable environmental impacts. After the construction of an open-cut gold mine and an ore-processing facility on Misima Island, Papua New Guinea in 1988, large increases of sedimentation caused a decrease in tissue-layer thickness of a nearby coral reef. Mining in the Ok Tedi Mine also increased sedimentation in the Ok Tedi River by 5-10 times. Increased sedimentation of the river is caused by high contents of dissolved copper in the inner floodplain.
