Sulfuric acid leaching of zinc silicate ore under pressure ...
De Wet and Singleton, 2008, Gnoinski, 2007 used the Skorpion sulfuric acid leach/solvent extraction process to extract zinc from nonsulfide ores in which the silica was successfully precipitated by adding CaCO 3. Unfortunately, iron cannot be easily eliminated from the organic phase in solvent extraction.

An effective leaching step is critical to the success of the operation, as this sets the stage for the amount of recovery possible. A variety of leaching methods exist, with the primary approach being heap leaching, a process in which crushed ore is piled onto a heap irrigated with a leachate. As the leachate percolates through the heap, it picks up the target metal and is collected as a pregnant liquor.
