Abstract
A system for producing significant quantities of noble metals from low-grade ore. A mixture of particulate feed containing small amounts of noble metals, a base metal, and activated carbon are placed in a non-conducting container. The container is surrounded by a coiled transmission line and heated via a combustion chamber. Pairs of electrical pulses having equal amplitudes and opposing directions are applied to each end of the transmission line so that the opposing pulses collide within the transmission line, the collision points traveling in a sweeping motion along the transmission line. Other pairs of pulses are sent in repeated cycles of multi-chord pulse trains, each chord having a specific frequency ranging preferably between 5000 to 7000 cycles per second.
