'Unprecedented' corrosive chemical leak at Vietnam alumina refinery.
The latest in a series of environmental fallouts has hit the Central Highlands. Workers at the Nhan Co alumina plant in Vietnam’s Central Highland province of Dak Nong last week discovered a broken pipeline containing the corrosive chemical sodium hydroxide. Some 9.6 cubic meters of sodium hydroxide has leaked from the plant, posing serious environmental threats to nearby residents. Sodium hydroxide is used at high temperatures to wash aluminum ore, also known as bauxite. Alumina is a white powder made from bauxite ore for producing aluminium. It sits between bauxite and aluminum in the light metal's production process chain. The leaked chemical has reportedly penetrated an area of 600 square meters, and some of it has been flowing into a stream, state media reported. The incident occurred on July 23 when a pipeline burst as the sodium hydroxide was being pumped to the production area.
