Mine Waste Is Being Dumped Directly Into the Ocean All Over the World
Picture a 4-foot diameter pipe running into the ocean filling the offshore canyons at a rate of 160,000 tons per day. The pipe runs from an enormous gold and copper mine directly into the Indian Ocean. The pipe is filled with mine “tailings”—a toxic sludge of heavy metals, rock and coagulants mixed in with the pulverized mine wastes that spreads and covers the seabed dramatically impacting plant and animal life and polluting the surrounding water. That is the Deep Submarined Tailings Disposal (DSTP) system at Newmont Mining’s Batu Hijau copper and gold mine in Indonesia.
Although Batu Hijau is the biggest mine that is using DSTP, at least 16 mines in eight countries are also using DSTP, with others to follow. Indonesia, Papua New Guinea and Norway lead the way using DSTP at their mines. In Chile, mines in the mountains north and east of Santiago are proposing to run pipes 50-100 kilometers so they can dump into the canyons of the Pacific Ocean off of the Chilean coast. The enormous Los Pelambres Copper Mine in Chile proposes to use DSTP in the future, discharging its wastes directly into the ocean.
