The impact of mining operations can cause severe damage to the environment, include morphological changes, loss of biodiversity and ecosystem disturbance. We are committed to restoring mining sites in use or no longer in use. We research to determine the optimal use of the post-mine site. We put in place long-term rehabilitation plans which are monitored regularly. These involve mainly appropriate replanting to achieve successful land and ecosystem renewal.

Slag management. We are constantly reviewing our operations in order to ensure that environmental damage is minimised. Nickel is extracted from its ores through the process of pyrometallurgy. This process, which involves the roasting of large quantities of ore, produces scoria, a byproduct that is made up of ferrous and pyrite oxides. It’s a vitreous and innocuous mix and does not contain any toxic substances. Our main focus is the management of this slag and we are currently examining ways that this product could be economically exploited. For instance, it can be used in the development of materials for road, airport and port construction, in naval facilities and in the creation of prime fire-proof bricks.

Waste management is a serious issue for Larco. Substantiated studies conducted by the National Center of Marine Studies confirm that the specific material (that ends up in the sea) does not harm the flora and fauna of the aquatic environment. Other studies indicate the added value of scoria. The company examines the potential commercial applications of the product, which has been unfairly labeled as toxic refuse.

Hydrometallurgy. LARCO is also considering implementing an alternative process which promises less environmental risks while delivering superior results. Hydrometallurgy is a process that uses aqueous solutions to purify metals or mineral concentrates. In the mining industry, hydrometallurgy is seen as the way forward. The suitability of the ore in terms of permeability and mineralogy, the potential of the reserves, the strong field infrastructure and our experience strengthen the project’s viability.

Energy modernisation programme. Our energy modernization programme will cost around 37 million euros and is part of the Ministry of Development’s co-financed Entrepreneurial Programme to save energy, protect the environment and improve employees’ work conditions.
