Mining companies in Chile are doing their best to protect the environment and develop more sustainable production methods.
By aiming to protect local aquifers from depletion and support continuous copper production, the聽Escondida Water Supply聽project was born.
Project construction included a new seawater desalination plant that is linked to the Escondida mine site in the Andes by two 105-mile (170-kilometer), 42-inch (107-centimeter) diameter lined pipelines installed on the Pacific coast at Coloso Port in Antofagasta.
Water is transported to over 10,000 feet (3,100 meters) above sea level by four high-pressure pump stations from the port across the Atacama Desert to a reservoir at the mine.鈥疘n addition, we installed 75 miles (120 kilometers) of new 220-kilovolt transmission lines, built鈥痶hree new substations, and expanded four existing substations to power the system. The new plant includes an offshore intake and outfall system more than 65 feet (20 meters) below the surface of the Pacific Ocean.
The system brings seawater into the desalination plant, filters鈥痬uch of its dissolved mineral and biological content using a reverse osmosis process and circulates鈥痚xtracted brine and other material back into the ocean. The desalinated water is then pumped to the mine.

The Atacama Desert, a portion of which is home to the Escondida complex, is one of the driest places on Earth.
Average annual rainfall in the desert totals roughly six-tenths of an inch, or about 15 millimeters. Some locations, including Iquique, to which 8868体育app下载 is no stranger, receive much less moisture鈥昽n the order of 80 percent less.
In some parts of the Atacama鈥晈hich extends in a relatively narrow band from southernmost Peru into northern Chile鈥昲umans have never recorded any precipitation. And yet more than 1鈥痬illion people call it home.
