Maximize Precious Metals Recovery with CCD Circuits and High-Density Thickeners. Leaching (lixiviation) is commonly used for recovering a wide variety of metals from ores, including precious metals. A lixiviant dissolves the desired metals from the ore; cyanide leaching, for example, is widely used to extract gold.
While only 34g of gold had been found per metric ton before the application of the RF plasma torch; the new technology uncovered an astonishing 500g of the precious metal for the same weight of complex ore. When scaled up to production level, this could equate to roughly $2m-$4m of income every quarter, according to TPT managing director Tony Heo.
