Reducing fresh water use in the production of metals
An average copper extraction of 97.3% was achieved while fresh water consumption was decreased from 1.63 m 3 /t concentrate to 0.67 m 3 /t concentrate through salt water substitution. Conceptual economic benefits of salt water addition to the flowsheet are presented.

Water Requirements of the Copper Industry - USGS
WATER REQUIREMENTS OF THE COPPER INDUSTRY By OBVILLB D. MUSSEY ABSTRACT The copper industry in 1955 used about 330 million gallons of water per day in the mining and manufacturing of primary copper. This amount is about 0.3 percent of the total estimated withdrawals of industrial water in the United States in 1955.

However, where copper pipes corrode they can release copper into your drinking water to a level that can affect its quality and safety. The information contained in this guide will help you identify signs of copper corrosion and provide advice on how to minimise its effect on your health.
Mining Water Use - USGS
The mining water-use category includes groundwater and surface water that is withdrawn and used for nonfuels and fuels mining. Nonfuels mining includes the extraction of ores, stone, sand, and gravel. Fuels mining includes the extraction of coal, petroleum, and natural gas. Water is used for mineral extraction, quarrying, milling, and other...

Health Effects of Excess Copper - Copper in …
The copper water concentrations ranged from 0.06 to about 5 mg of copper/L in the first draw water. Roberts et al. (1996) examined communities made up of more than 100 people in Delaware. They considered communities in which 10% of the water samples, measured during a statewide survey in 1995, had copper concentrations greater than 5 mg/L.

The gradual fall of ore grades (which is the quality of copper in the rock) also leads to a greater use of water to extract copper. As such, water consumption is expected to increase 4.2% per year towards the year 2029. To learn more about mining investment opportunities in Chile, take a look at the following article. Source: AFP

Copper in health - Wikipedia
Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms).In humans, copper is essential to the proper functioning of organs and metabolic processes. The human body has complex homeostatic mechanisms which attempt to ensure a constant supply of available copper, while eliminating excess copper whenever this occurs.
