The copper left at the bottom of the holding furnace is fed through two more furnaces for further refining where it is heated to temperatures of up to 1250 degrees Celsius. What s left is 99.7 per cent pure molten copper. This glowing golden substance is then poured into a cast to set into a 350 kilogram copper anode slab.
• Copper is 100 recyclable without loss of quality • Copper is the most recycled metal after iron and aluminium • Around 40 of the demand for copper within Europe is supplied from recycled copper. • Recycling a tonne of copper uses 20 of the energy that would be used to mine and extract the same copper.
Hazardous substances are broadly defined under CERCLA and have included mining milling and smelter wastes that are currently excluded from regulation under RCRA. Regulators have the authority to use special funds undertake emergency responses and hold all historical owners or contributors — principal responsible parties — liable for
Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.
