For an agitated leach plant processing 2 g/mt gold ore, it requires a production rate of at least 5,000 mt/d of ore. Even in those cases, while the Carbon Converter has a payback of about one year, but it does not significantly move the economic needle since it increases gold production only 1% to 1.5%."

Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.

The extraction and processing techniques for platinum and gold also differ. Gold is typically extracted using various methods, including placer mining, hydraulic mining, and heap leaching. Once extracted, gold ore is often processed through crushing, grinding, and chemical treatments such as cyanidation to separate the gold from the ore matrix.
