Benefits
Existing SA production depends on burning sulfur from Oil & Gas to make sulfuric acid. Travertine SA production recycles sulfur within a closed loop, minimizing any sulfur feedstock requirement.
Existing SA production requires large plants to achieve economics of scale. Travertine SA production uses a modular electrochemical units that allow smaller scale plants.
Most SA ends up as gypsum waste after use. Travertine recycles the sulfur and makes cementitious materials, gypsum-free.
Applications
In copper heap leaching, sulfuric acid acts as a powerful lixiviant that chemicaly dissolves copper from oxide and some sulfide ores. This process begins by spraying a dilute sulfuric acid solution over large heaps of crushed ore. As the acid percolates through the pile, it reacts with copper minerals to form a water-soluble copper sulfate solution, known as the pregnant leach solution (PLS). The PLS is then collected at the base of the heap for downstream solvent extraction and electrowinning (SX-EW), where pure copper cathodes are produced.
