  • Geosynthetic Lining for Mining Industry

    Geosynthetics are used in construction of various components of modern mining facilities, including process solution ponds, heap leach pads, stormwater containment, wastewater treatment ponds and closures. Harsh environmental conditions provide a challenge to engineers designing the projects. In addition, increasing environmental and cost pressures are requiring lining systems to achieve greater performance levels than ever. GCLs are rapidly becoming a desired component of mining liner systems because of the benefits they provide in cost effective construction, environmental compliance and process solution leak reduction. In weather-sensitive remote or high-altitude locations, GCLs offer far greater installation efficiencies than compacted clay.

  • Activated carbons for precious metal recovery and mining industry

    Activated Carbon has a major role in various applications across the mining industry, particularly in gold recovery. Activated Carbon fulfills a crucial role as the key element in Heap Leach Circuits, Carbon in Leach, and Carbon in Pulp processes. Carbon Activated Corp. has a well developed history of supplying goldmines across the USA, South America, Turkey and a number of other gold producing territories. We are a major manufacturer of activated carbon specialized for the gold mining industry and precious metals recovery to be utilized in both Carbon Leach and Carbon Pulp methods.

  • Environmental protection solutions for the mining industry

    GEOWEB geocells offer a better “solution set” to soil stability challenges for accessing sites over soft ground, controlling and containing stormwater, protecting geomembranes for basins, tailings, and heap leach pads, and reclaiming slopes at the time of closure. Through 3D confinement and strengthening of infill, less material—even on-site waste rock—may be used. GEOWEB solutions offer increased speed of operation, lower maintenance, safer installation, and a lower total cost of ownership.

  • pH/ORP Sensors for Metallurigical Applications

    Importance of pH Measurement - Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate measurement. Processes such as cyanide leaching (e.g gold) and solvent extraction (e.g. copper, nickel, zinc) require pH and ORP to be at very specific values to yield the desired chemical species. pH may need to be controlled as precisely as ±0.05 for some processes. Even where this level of precision is needed, process environments are typically extremely aggressive to the sensor.

  • Solutions for recovering metals

    The mining industry relies on Calgon Carbon’s Granular Activated Carbon (GAC) to recover gold and other precious metals. Calgon Carbon’s ISEP® Technology is used to recover precious, rare earth and base metals, uranium, copper, nickel and zinc from ore, waste and reclaim streams. Our high-quality activated carbons have been developed and successfully proven to maximize efficiency by reducing the loss of precious metals and the consumption of carbon in three precious metal extraction techniques: Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC). When Ion Exchange is employed for metal recovery in leach and waste streams, Calgon Carbon’s ISEP ® system provides a continuous, consistent and high purity concentrated product while minimizing the use of chemicals, resin and wastes. Calgon Carbon’s continuous ion exchange systems are the most flexible, robust, and accepted in the industry.
