coal mines in the world. The 2008 coal production in Cerrejon was calculated in 31.2 million tons. There are also smaller coal mines scattered throughout the rest of the nation. Since 2000 government participation in the production of coal has been decreasing, and there has been a shift to private domestic and foreign investors. Major changes have occurred in the institutional framework of the coal industry in recent years. In particular, in 2000 the government sold the stakes that Colombia Coal ( Carbocol), a state-owned company, had in Cerrejón, and the new mining code introduced in 2001 led the government to concentrate on its role as regulator through the Ministry of Mines and Energy.

Gemstones

Colombia is the main producer of finer quality emeralds worldwide. Colombia produced 2.7 Mcarats (540 kg) of emeralds during 2008. Emerald mines are located both in the Boyacá and Cundinamarca Departments. Colombian emeralds constitute 50-95% of the world production, the numbers depending on the year, source and emeralds grade.


Relevance

The Colombian mining industry remains as one of the most dynamic and promising sectors of the Colombian economy, in just one year the investment has reached record figures in excess of two billion dollars and the trend in the short term is not reversed. The mining industry contributes with the economic growth and social development and the development of the regions where the activity is legally established. In addition this demonstrates that the contribution in the social and environmental component is higher than the industry average. Government efforts to expand mining in Colombia were needed to encourage private sector investment. In the late 1980s, much of Colombia remained inadequately charted, and reserve estimates were considered only marginally reliable. The government set a policy of developing infrastructure (roads, electricity, and communications), providing technical assistance, and encouraging sound credit and legal policies to minimize problems with land titling. Through joint ventures and the promotion of small mining companies, government officials believed that the mining sector could contribute more to national employment, income, and wealth.
