Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Recycling is a major source of copper in the modern world. A combination of economic and regulatory factors are now at work to make metal recycle and water reuse very attractive.
Previously, cable and wire materials were often lost in the treatment and sorting process, resulting in a financial loss due to the high proportion of copper they contain. TOMRA sorting technologies are capable of detecting these wires, transferring them to a metal product and then finally sorting them in a further step into a cable fraction of outstanding purity.
Winning with electrode design to reduce energy costs in traditional processes and UAT Reverse Osmosis (RO) Membrane Filtration Systems to meet any tap or brackish application need. Nickel and cobalt production, precious metal refining (gold, silver), recovery of copper from bleed streams or valuable metals from industrial wastewater, are some of the applications of our titanium DSA anodes.
The mining industry uses chemicals as ‘flotation’ agents in the recovery of sulphide minerals containing metallic elements (e.g., copper, nickel, silver, gold) from ore slurries. Sodium ethyl xanthate (SEX) is one of most common flotation agents, and it decomposes to form ethanol, carbon disulfide CS2, and Carbonyl Sulfide COS. These harmful gaseous compounds must be monitored from the indoor air at the enriching plant.
Non-Ferrous Metal Recycling is a large industry focusing on the recovery of metals such as aluminum, brass, copper, and even precious metals from electronic scrap. The applications and needs of non ferrous metal recyclers vary greatly. These can include a large corporate recycler buying UBC bales for shredding to be converted back into beverage cans or a small recycler who is recovering precious metals from circuit boards or catalytic converters.
Non magnetic metals such aluminum + copper can be separated using eriez eddy current separators or meta sorters. Eriez equipment, either as individual units or complete systems, is designed for efficient + economical processing of municipal solid waste, co-mingled recyclables, shredded automobiles, Electronic Scrap, Glass Cullet, Plastic (PET), foundry sand and many other resource recovery options.
Electric and electronic waste (WEEE), are coming from technology products such as home appliances (washing machines, vacuum cleaners), computers and tools. An economy based on the consumption such as today, provides a continuous increase of WEEE, and determines an increasing risk of dropping out in the environment or in landfills, with the consequences of pollution of soil, air, water and health human repercussions. These products should be handled properly and used for the differential recovery of the materials...
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...
