The Recovery of From Pyrite Elemental Sulphur and Pyrrhotite
S ULPHUR production in Canada from all sources for the year 1953 amounted to about 375,000 tons. Except for 16,000 tons of elemental sulphur derived from natural gas, this production was in the form of by-product pyrites, liquid sulphur dioxide, and sulphuric acid. In the same year, Canadian industry imported 35.9,000 tons of elemental sulphur from the United States. The cost, including transportation charges, to Canadian consuming plants ranged from $35.00 to $45.00 per long ton, depending upon location.
