In 2000, small-scale mining in Chile was responsible for the production of some 45,000 metric tons of copper, 13,650 kg of silver, and 3,500 kg of gold, representing 0.97%, 1.1% and 6.5% of national production, respectively. The sector overall employs an estimated 1,700 workers, some 5.1% of the country's mining labour force.
Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also cause …

"We're on the verge of a very major large-scale copper discovery, perhaps one of the biggest in New South Wales in recent times." And with a global mining sector that desperately needs more copper resources, one can't help but see dollar signs. "When you look at the number of major copper deposits coming online, they're just not there.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

These mines were able to process large quantities of low-grade copper ores at very low cost. Copper production reached a peak of 720 000 t in 1969, the same year that the nationalization discussions picked up speed. By the time nationalization was being completed in 1973, production had dropped slightly to 700 000 t.
