Chile is a country with large reserves of minerals. In metal mining but also production of copper, iron, molybdenum, manganese, lead, zinc, gold and silver. Of these products, the most interest are the copper and molybdenum, the latter being a byproduct of copper production. As a result of this wealth, mining has always been the main activity of the country.
Copper In Chile, copper mining is shared between private and state enterprises. Codelco Chile, Corporación del Cobre, is an autonomous state enterprise, the country's largest copper mining and the main copper producer in the world.
The main products sold by Chile, are the cathodes and copper concentrates, which are exported for processing and to produce manufactured goods. Their fate has always been the industrialized countries and now also the industrializing countries like China. Underlines the high concentration of exports to markets in Asia and Western Europe, reflecting the high degree of dependence on the marketing of copper with these markets.

- includes non-metallic mining activities mineral resource extraction, after adequate treatment, are transformed into products applicable in various industrial and agricultural use due to its physical and / or chemical. Hence, the public and private interest in its development is aimed at both its production phase and in the end-use products.
This activity is seen as an opportunity for small and medium scale mining. With the exception of large salt resources of the north and limestone, most nonmetallic minerals are exploited at the level of small size, usually in open pit operations, initially followed a simple treatment, which may include grinding, classification, washing, drying, etc.Cabe noted that applies the concept of mining product "for those substances that can be marketed, is a simple mineral or a derivative obtained via treatment of industrial type, usually integrated into the mining phase. It therefore has a broader meaning to the concept Geological "mineral resource" Given the diversity of non-metallic products considered of interest and only for purposes of analyzing their behavior, they are classified into 4 groups by virtue of its economic importance and characteristics of your market:
