SLAG RECYCLE
In the world, the Southwestern region of the U.S.A. has the second-largest gold deposits through Nevada, California, and Arizona. There used to be several thousands of mines and smelters in these areas during the gold rush in the ate 1800’s.
There remain a few hundred closed smelters and over 20 million tons of slags that are stockpiled around the closed smelters. Currently, in these areas, we have acquired 18 stockpiles of slag. As a matter of old metallurgy of technology, the various slags still contain Iridium, Platinum, Rhodium, Gold, and Silver which could not refine them due to minimized smelting temperature and loss of atoms.
Several scientific studies for over 20 years has revealed the fact that modern technology can recover precious metals. Smelting processes are done for the removal of the remarkable metals, still leaving metals behind in the slag suggests that the existing fire assay process (a smelting process) would fail to recover those metals. Through less energy usage normal refining techniques are unable to recover precious metals in slag. Any useful process must utilize enough energy (in whatever form, electrical, thermal, chemical, etc, or in combination), to break the complex bonds. Our cold plasma process uses high-electrical energy in conjunction with chemistry to break these bonds in conjunction with the hot plasma process line to break the bonds and ionize the metals.
