Coal

It is a black sedimentary rock, very rich in carbon originated by the accumulation, burial and transformation with carbon enrichment of organic waste of vegetable origin accumulated in marshy, lagoon or shallow marine areas. Coal is valued for its energy content.

We mainly work with Anthracite and soft coal with great calorific value and a selection of different grain sizes.

Historically, coal mining has been a very dangerous activity, so improvements in mining methods, monitoring of poisonous gases, drainage of gases, electrical equipment and ventilation systems have reduced many risks, such as falling rocks, explosions and unhealthy air quality. Nowadays it is very important that workers have great skills and that they are well trained.

We always have a stock of 250.000 tons
ready to be shipped immediately
