precious metal waste Applications

  • 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.

    Metal Sorting - Electronic Scrap Sorting

    The recycling of disused and obsolete electrical and electronic equipment is gaining more and more importance world-wide. Waste electrical equipment is an incredibly rewarding source of raw materials. In Waste electrical equipment, up to hundreds of times more precious metals can be found per ton of material than in the primary source of raw material, ore. The goal for TITECH and the industry as a whole is to utilise electronic scrap recycling and sort out pollutants on one hand and profitable components in high purity on the other. For electronic recycling purposes, the EU classifies W??? into 10 categories. After separate collection of TVs, fridges and so on, they are processed and sorted in electronic scrap recycling systems. The average content of thus gained materials is as follows: metals (50%), plastics (30%), glass (10%) and other materials (10%).

    Recycling equipments for electronic waste recycling (WEEE)

    The content of WEEE (electrical and electronic waste) gives recyclers various initiatives for recycling. It contains hazardous substances, such as lead, mercury or certain flame retardants, as well as precious metals like gold and silver. In 2012 approx. 64,900.000 ton electronic goods where produced and 49.000.000 ton electrical and electronic waste (WEEE) was generated. As the amount of sold electronic goods rise, the amount of WEEE rises. It is vital that this waste is taken care of properly.
