Most lowlevel radioactive waste is typically sent to landbased disposal immediately following its packaging. Many longterm waste management options have been investigated worldwide which seek to provide publicly acceptable, safe and environmentally sound solutions to the management of intermediatelevel waste and highlevel radioactive waste.

Copper Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and .

The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and groundup limestone) to give a basic pH, pine oil (yes, it comes from trees a byproduct of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...

Porphyry copper deposits, which are associated with igneous intrusions, yield about twothirds of the world's copper and are therefore the world's most important type of copper deposit. Large copper deposits of this type are found in mountainous regions of western North

Of the total volume of waste materials the group generated in 2015, 83% was reused internally, while, in its copper recycling system, around 26% of its total scrap production is recovered. Sumitomo Metal Mining has similarly taken great leaps in its recycling commitment, with its recovery rates of copper scrap almost doubling in the five years following 2010.
