The results of the testing of copper levels within the Gardner WWTF were as expected. The total copper level decreased linearly as it progressed through the plant's treatment stages. The plant influent had an average total copper value of 79.21 parts per billion (ppb), while the effluent had an average total copper value of 23.15 ppb.
Secondary copper can be used for the manufacture of these materials, though still within stipulated quality limits for impurities. Where scrap copper is associated with other materials, for example after having been tinned or soldered, it will frequently be more economic to take advantage of such contamination than try to remove it by refining.

Copper recycling and reuse. Reduce: Copper products are hard wearing and last for a long time and will often still function long after they have been superseded by newer models. Reuse: Goods such as mobile phones, washing machines and cookers, which are still in working order, can be passed on to others for reuse. Recycling: Copper containing waste such as WEEE (Waste Electrical and Electronic ...
Aug 10, 2018· Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore.
Redundant or waste radioactive sources from medical applications and old dials and gauges luminised with226Ra have also found their way into the scrap metal chain. Naturally occurring radioactive material (or NORM) or low specific activity (LSA) scale - NORM typically contains uranium-238 (238U) and thorium-232 (232Th) and their associated ...
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting ...
Mining wastes include waste generated during the extraction, beneficiation, and processing of minerals.
