:: Vale Investing US$390 Million in Implementation of Dry Stacking Tailings Disposal Tech from 2020

 

Following the Brumadinho disaster, Vale in a statement says over the years it has been continuously investing in the maintenance and safety of its dams, “with standards being updated and in continuous alignment with the most rigorous international practices.” The increasing and relevant investments in dam management and Health and Safety initiatives demonstrate Vale’s commitment to providing the necessary resources to preserve the Health and Safety of its employees and the surrounding communities.” The investments in dam management in Brazil have been steadily strengthened and will amount to R$256 million (approximately US$70 million) in 2019 according to the budget approved by the company in 2018, reflecting an increase of around 180% when compared to R$92 million (approximately US$30 million) invested in 2015.

From 2016 to 2019, investments in dam management will total R$786 million (approximately US$220 million), being applied to initiatives related to the maintenance and safety of dams, such as maintenance services, monitoring, improvements, auditings, risk analysis, revisions of the Emergency Action Plan for Mining Dams (PAEBM), implementation of alert systems, video monitoring and instrumentation, becoming the most significant category in relation to investments in dams and waste dumps, representing more than 30% of the total amount invested.

“Vale’s investments in new tailings dams, all built by the conventional method, reflect the company’s operational needs and the implementation schedule of each of the projects in execution. Since 2015, Vale has conducted important tailings dams construction projects, such as the Brucutu Norte dam (2015) and Forquilha V dam (2016) in Minas Gerais, and new projects have been started, such as the Maravilhas III dam (2016), also in Minas Gerais. It is important to emphasize that all of Vale’s new dam constructions follow the conventional construction method, in line with the decision made in 2016, after the disruption of the Samarco dam in Mariana, to render inactive and decommission all upstream dams, which will be accelerated as per the Press Release issued on January 29th, 2019.”

Vale’s plan is to increase the share of dry processing in its production to 70% by 2023, and consequently reduce the use of dams in its operations. Furthermore, in order to treat the tailings from its wet processing, Vale informs that it plans to invest, starting in 2020, approximately R$1.5 billion (about US$390 million) in the implementation of dry stacking disposal technology. This initiative goes along with the acquisition of New Steel announced on December 11th, 2018, with innovative technologies for the dry beneficiation of iron ore.

“The investments in Health and Safety are primarily destined to the electrical rehabilitation, in line with Regulatory Norm 10 of the Ministry of Labor – Safety in Facilities and in Electrical Services (RN10), structural rehabilitation and operational adequacy, firefighting and prevention systems in line with Regulatory Norm 23 of the Ministry of Labor – Fire Protection (RN23), in addition to other actions aimed at risk mitigation and compliance with legal requirements.”

In 2015, Vale executed important electrical rehabilitation projects in the Alegria mine, in Minas Gerais, and Carajás mines, in Pará, and the firefighting program of the Fábrica, Brucutu and Pico mines, in Minas Gerais, and Carajás mines, in Pará, in addition to the structural rehabilitation of the Brucutu plant, in Minas Gerais and, consequently, investments in 2016 were reduced to R$435 million (about US$125 million). Since then, Vale has been increasing its investments in projects related to Health and Safety, and in 2019, R$877 million (approximately US$233 million) are planned to be used, representing a growth of 48% when compared to 2015.
