A metal-dissolving apparatus has been patented, featuring a reactor with metal and solution inlets and outlets, as well as a ventilation port. The apparatus is characterized by its height being less than its length, with the option for multiple reactors within the system. A reactant distribution device ensures uniform distribution of the metal-dissolving solution throughout the reactor, which has a height to width ratio of less than one. The self-supporting apparatus is designed to fit within a standard shipping container, making it versatile for various applications.

The patented process involves providing a metal-dissolving solution into the apparatus with spatial uniformity, flowing it through under low hydrostatic load to dissolve metal from substances, and discharging the solution. The process can be continuous or batch, with the solution distributed through perforated pipes for even coverage. A re-circulation loop allows for the reuse of the metal-dissolving solution until it reaches a threshold amount of dissolved metals, creating a pregnant leach solution. This innovative approach to metal dissolution offers efficiency and sustainability benefits, with potential applications in various industries requiring metal extraction processes.
