However, it is also applicable in locations where smelter acid is not available by the purchase of sulfuric acid or the manufacture of sulfuric acid from sulfur or pyrite. In addition, it offers the opportunity to recover copper from an entirely different set of ores and mining byproducts than is possible by smelting; namely, oxidized materials.

SAIMM Sulfuric Acid

The papers in this issue focus on sulfuric acid. Sulfuric acid has become an integral part of the mining industry and today there are more sulfuric acid plants operated in the mining industry than in the chemical industry in South Africa. This revolution took place in the 1950s with the advent of the uranium extraction and recovery process.

Copper Mining and Extraction: Oxide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. A byproduct of the smelting and converting furnaces is sulfuric acid.
