In 1989, the start-up of the sulfuric acid plant marked a key milestone in Horne Smelter’s commitment to the environment and its community. From that point on, SO2 emissions have steadily decreased.
Today, more than 96% of the sulfur from the process is used to produce 640,000 tonnes of sulfuric acid per year. This by-product of the smelting process is sold to various customers, mainly on the east coast of the United States and in western Canada, where various industries use it to manufacture automotive batteries, fertilizers, etc. Because our acid is of the highest quality, it is also used in the food and pharmaceutical industries.
