Our latest orders in South America, including Cangas 2 Meneração, River Gold, and Arica Mineraco, highlight the accelerating demand for intensive leaching solutions that deliver accelerated recoveries backed by proven reliability.
First launched in 1997, the ILR was the world’s first commercial intensive leach production unit. Africa was among the earliest adopters, recognising its ability to replace open tabling with enclosed leaching, dramatically improving both security and safety.
Today, ILRs are trusted in nine regions worldwide, from West Africa to Oceania, Asia, the CIS, and the Middle East. Each installation reflects the industry’s shift toward modular, automated, and environmentally conscious solutions.
At the heart of the ILR is its rolling barrel design, built for efficiency and scalability. Here’s how it delivers:
- Intensive leaching chemistry: Concentrates are mixed with a 1–2% sodium cyanide solution and an oxidant inside a rolling drum.
- High-shear kinetics: Baffles ensure constant contact, stripping oxidation layers from gold particles to accelerate recovery.
- Batch and continuous modes: Batch mode suits high-grade, low-tonnage concentrates (under 20 tonnes per batch). Continuous mode is ideal for higher-volume, lower-grade concentrates from flotation or IPJ circuits.
- Automation and safety: Chemical handling is automated, and leach parameters are electronically controlled, making operations faster, safer, and more consistent.
The ILR consistently delivers over 98% recovery of free gold, unlocking more gold with less risk and greater certainty.
- Higher recoveries, faster, guaranteed: Gekko’s promise to every ILR customer.
- Optimised for both gold and silver concentrates, ensuring versatility across ore types.
- Reduced manual handling strengthens site security while lowering operational costs.
The latest orders in South America reflect a clear industry trend: demand for modular, automated, and sustainable solutions is accelerating. By reducing manual handling and chemical exposure, ILRs not only improve site security but also advance safer, more sustainable mining practices.
With its proven track record, the ILR continues to set the global standard for intensive leaching, redefining gold recovery with efficiency and innovation.
