Abstract
The present invention relates to methods for leaching products from source materials, especially combustion products from fuels including coal, bitumen, coke, oil, and other fuels that produce an ash such as flyash, bottom ash, etc. that have valuable components including minerals, precious and other metals, compounds, and the like using functional electrolytic water. The methods may produce other products, some of which are used in a process integrated into the pollution control equipment of a power plant.
Claims33
A method for leaching constituents from a source material comprising:
- generating an acidic aqueous leaching solution;
- contacting the acidic aqueous leaching solution with the source material to form a mixture;
- removing at least one product from the acidic aqueous leaching solution and source material mixture;
- and
- producing an alkali stream while generating the acidic aqueous leaching solution.
The method of claim I wherein the source material is contacted with the acidic aqueous leaching solution using equipment or methods selected from the group consisting of mix tanks, heap leaching, a series of tanks, and combinations thereof.
