Mineral activities

Lime is used in the recovery of metals. It also has an important role in controlling the pH in the waste water from this industry.

Environment

Recently, special attention has been given to the deterioration of the environment. Acid rain and toxic and dangerous industrial waste have contributed to worsen this situation. Lime helps solve these problems. Its alkaline content, its low costs and ease to work with are fundamental characteristics of this product.

Water

It is used to control the pH, it precipitates phosphates and nitrates. It eliminates odours and immobilises toxic metals. Hydrated lime is a harmless product in any technique to purify water.

Paper

In this industry, lime is used as a cautery. It is also used as a whitening agent and to treat waste water.

Agriculture

Lime, or the correctives, are the fertilisers of choice for acidic and clay soils. The effective neutralising values obtain a practically instantaneous response from crops and harvests, thereby increasing the productivity of the fields.

Roads and public works

As a binder and a cementer, lime can stabilise clay soils which are not suitable for the construction of road surfaces, thereby making them able to support roads, avenues, parking, etc.

Sugar

Lime is used to remove phosphate and organic composites and in its clarification.

Construction and restoration

There are centuries of experience in this area. Lime based mortars are long-lasting, do not crack, support climatic shocks, offer greater resistance to the propagation of sound, are better to work with and create an obstacle to the penetration of water – construction's worst enemy.
