Canada’s second-largest source of acid rain, the 60-year-old copper smelter of Noranda Inc. in northwestern Quebec, is getting a new sulphuric acid plant.
The plant, to help cut back on sulphur dioxide emissions that contribute to acid rain, will cost $125 million, with the federal and Quebec governments each spending $41.6 million and Noranda the remainder.
This latest development by the company to reduce emissions at its Horne copper mine smelter at Noranda, Que., will provide an acid plant with a capacity of 350,000 tonnes per year. It is estimated the plant will cut annual sulphur dioxide emissions to 276,000 tonnes by 1990. (Sulphur dioxide emissions in 1980 totalled 552,000 tonnes.)
The government funding is in the form of a repayable interest- bearing contribution. The extracted sulphuric acid will have industrial application.
The Inco Ltd. smelters at Sudbury are the country’s number one source of acid rain.
