Gravity Concentrates

High-grade gravity gold concentrates, produced from hard rock recovery circuits, are typically shipped to offshore smelters for final refining. This model exposes miners to high transportation costs, extended settlement times, and heavy treatment charges. In many cases, concentrates also contain arsenic, antimony, or other deleterious elements that trigger severe smelter penalties, further reducing net returns. For operators in remote regions such as Alaska, these factors can significantly erode the profitability of even high-grade concentrate production.

​

Innovation Mining’s proprietary RZOLV™ non-cyanide lixiviant provides a cost-effective and environmentally superior alternative to conventional smelting. As a water-based reagent, RZOLV™ is engineered to selectively dissolve gold from gravity concentrates under ambient conditions, achieving high recoveries without the need for high-temperature furnaces or hazardous cyanide handling. This approach not only lowers operating costs but also eliminates the financial and logistical burden of offshore smelter reliance.

​

By replacing smelters with regional or site-based RZOLV™ processing facilities, miners can directly recover gold into doré, capturing a greater share of the value chain. Processing concentrates locally also reduces exposure to shipment risks and accelerates cash flow, while residues generated by RZOLV™ treatment are far cleaner and easier to manage than arsenic-rich smelter slags.

​

The adoption of RZOLV™ represents a transformative step for the gold industry, modernizing the concentrate monetization pathway. Instead of surrendering margin to smelters, miners can apply a proven, non-cyanide technology that delivers high recoveries, improves environmental outcomes, and ensures that the full economic potential of their gravity concentrates is realized.
