Evonik supports leaching in the metals and mining industry with HYPROX® 600, a high-quality hydrogen peroxide solution used as an oxidizing agent in hydrometallurgical processes. HYPROX® 600 enhances ore leaching efficiency, improves concentrate preparation, and enables effective effluent treatment by breaking down harmful substances such as cyanides. Its environmentally friendly decomposition into water and oxygen makes it an ideal choice for sustainable leaching technologies. In addition Evonik’s AROSURF® surfactants support the improved penetrability of leaching agents hence improving and speeding up recoveries.
Leaching is a critical hydrometallurgical process for extracting valuable metals from ores by dissolving them in a liquid solution. Instead of physical separation, leaching uses chemical leaching agents—such as acids, bases, or oxidizers—to selectively dissolve metals, producing a pregnant leach solution (PLS) for further recovery through precipitation, solvent extraction, or electrowinning. This method is especially important for low-grade ores or complex materials where flotation or smelting is less efficient. Common techniques include heap leaching for gold, copper, and uranium, pressure leaching for refractory ores, and bioleaching, which uses microorganisms to enhance dissolution.
By combining performance and sustainability, Evonik’s HYPROX® 600 helps mining operations optimize metal recovery, reduce environmental impact, and meet the growing demand for eco-friendly mineral processing solutions.
