There are two distinct periods in the evolution of “Mining statistics of Spain”:


- Tables with data for each mine: production, employment, economic value of production, consumption of explosives, etc.

- Detailed report for each province: mines inventoried, companies, mining facilities, workshops, accidents, comments on the evolution trends for each year, etc.


- The only text is the foreword and the index

- Time series for the last 5 years include the total national production for:

  • Energetics (coal, uranium, oil and gas)
  • Metalic ores (cooper, iron, gold, etc.)
  • Industrial minerals (fluorite, quartz, feldspar, etc.)
  • Limestone, sand and gravel, gypsum, clays, dimensional stones, etc.

- Production of each substance per province:

  • Tonnes, laws (% content), working people (men-women), production value
  • Consumption: energy, explosives, water, etc.
  • Investments

- Destination of the production: metallurgy, cements, construction, chemical industries, exports, etc.
