Reduce cyanide consumption in your metallurgical operation by as much as 30% with the MACH REACTOR™

GoldOre (Pty) Ltd. proudly takes every possible step to assist in creating a more sustainable future for the environment. GoldOre’s ground-breaking technology, the MACH REACTOR™, has made several advances to reduce its carbon footprint, minimise waste, and lead as one of the most eco-friendly reactors on the market. One way this has been achieved is by reducing cyanide consumption by an astounding 30% by using the MACH REACTOR™ for pre-oxidation in gold leaching circuits.

During the extraction process, iron and sulphide are deleteriously leached to consume cyanide as ferrocyanide and thiocyanate. Ferrocyanide is a huge consumer of cyanide. Thiocyanate also causes other issues as it very difficult to destroy in SMBS/Air cyanide destruction processes, so it becomes an environmental concern.

Pre-oxidation with the MACH oxidises ferrous to ferric and precipitates ferric hydroxide and even more stable ferric oxyhydroxides. Sulphide is oxidised to sulphate in an exothermic reaction that produces sulphuric acid. Pre-oxidation also forms a surface film of ferric hydroxide on the surface of the reactive mineral which prevents it from leaching out when cyanide is added for the gold leach.

For semi-refractory gold ores, the MACH is also able to improve gold recovery. Thanks to the MACH REACTOR’s aggressive pre-oxidation techniques, much of the sulphide matrix is destroyed, releasing the bulk of the solid solution or chemically bonded gold. During this process, much of the environmentally harmful arsenic is precipitated assisting in an economical and environmentally friendly process. In order to achieve the best recovery results, the chemistry and grind of pre-oxidation can be adjusted to suit the specific characteristics of the ore as required. GoldOre has trade named this process as the GoldOre FerrateTM process.

Through the process of pre-oxidation, much of the environmentally harmful arsenic is precipitated assisting in an economical and environmentally friendly process. Using the MACH for pre-oxidation in gold leaching circuits is just one of the incredible ways that make the MACH one of the most environmentally conscious reactors on the market.

The MACH proudly makes conscious moves towards a more sustainable future by practicing more environmentally friendly processes.
