Gold Ore has found a way to harness this powerful energy and use it for something good. Chemical reactions are governed by the interaction of energy and matter. Imploding cavitating bubbles generate temperatures of up to 5,500°C and pressures of around 1,000 atmospheres, creating a highly reactive environment for mass transfer and chemical reaction.
