Sulfide precipitation of heavy metals

ABSTRACT This research program was initiated with the objective of evaluating a new process, the sulfide precipitation of heavy metals from industrial wastewaters. The process was expected to effect a more complete removal of heavy metals than conventional lime processing because of the much lower solubilities of metal sulfides than hydroxides.

Copper

Copper is one of the few tracer metals that is essential for all species. For the most part the biological requirement of copper is quite low as only a few enzymes such as cytochrome oxidase and superoxide dismutase require copper at their active sites. These generally rely on the oxidation-reduction cycling and play an important role in respiration.

Copper recycling and sustainability

The brass industry throughout the world depends on the recycling of brass scrap for its survival. Making brass from new copper and zinc would be uneconomical and wasteful of raw materials so, since new brass articles are made from recycled scrap, brass is said to be sustainable. In the UK brass manufacturers use almost brass scrap.
