Minera de Órgiva is the current operator of the mining concession "Lújar No. 30,411" located in the town of Orgiva (Granada).

It extracts fluorite (trade name fluorspar), which is considered a priority raw material mineral according to the Royal Decree 647/2002.

Orgiva is considered the capital of the region of the Alpujarra, which has always been linked to mining. The Phoenicians began the development of the field, followed by the Romans and so on until today.

During the years 70-80, under direction of the Penarroya Metallurgical Mining Company, the activity of the mine was in it’s glory years, reaching it’s own flotation plant and providing jobs for about 270 workers. The company closed in 1989.

In 2010 and with the addition of new partners, Minera de Órgiva reactivated the exploitation of the mine.

In 2010 Minera de Órgiva proposes a challenge, reviving the mining at a time and an area in which the crisis is hitting more crudely.

Today, Minera de Orgiva grows continuously , every day more families are involved in the project, directly or indirectly, improved facilities and resources is ongoing..

The local economic and social impact is obvious, improving the quality of life of our employees, we improve all of our neighbors´..

In Minera de Orgiva, our bet is for quality work, where training and safety are the key..

From the local to global. We always work with local businesses from gasoil supply, or supplying of helmets to international transport ............ because few know, but more than 70% of our production is exported..

...... And the outlook is for growth, not only in exports but as a project, while maintaining our commitment to the people, with the town, local businesses, local institutions..

And in particular, commitment with the environment. We perform an activity in which

• do not generate sterile
• no waste
• The concentration process is clean, using a mechanical process without using water or chemicals.

And our commitment is not only to not affect the enviroment, but for the immediate future we want:

• Regenerate old tailings
• Search with different local actors the perfect location for our future treatment plant..

MINING AND COMMERCIALIZATION FOR STEEL AND CEMENT INDUSTRIES

 

Fluorite (Industrial name fluorspar) is a mineral from the group of halides, formed by the combination of calcium and fluoride, which crystallizes in the cubic system. Formula CaF2.

Fluorite, from the Latin fluere (flow), owes its name to that property.

Its main use is in the production of hydrofluoric acid.

In the manufacture of steel, fluorite is used as a flux, lowering the melting point of steel, which is achieved with a dual objective, on one hand, facilitate and accelerate the formation of slag, reducing energy costs. This reduces heat loss and improves the thermal performance during the heating phases and refining Furnace.

Moreover, a slag with a low melting point has a higher ability to capture sulfur in the desulfurization, and reducing capacity greater scavenging inclusions, resulting in cleaner steel.

In the cement industry, the use of fluorite reduce thermal energy consumption by reducing the temperature clinkerisation. Moreover, the compressive strength increases by 15% when adding fluorspar to manufacture.

It can be distinguished by fluorite CaF2 content.

• Acid Grade – F2Ca content higher than 97%.
• Metallurgical Grade (Metspar) - F2Ca content higher than 70%.
• Content cement- F2Ca content higher than 35%..

Globally, the main metallurgical fluorspar producers are China, Mexico, Mongolia and Russia.
