Vale Sand

​​

At Vale, there are great investments in R&D because we are here to improve life and transform the future together!

By combining innovation and sustainability, Vale Sand brings benefits to neighboring communities, to the environment and promotes the generation of new businesses. Vale Sand comes from the processing of iron ore and stands out for its chemical uniformity, particle size and absence of organic matter. Vale Sand is considered a fine aggregate, with fine particle size and with its composition mainly constituted by quartz.

Characteristics suitable for various applications

We contribute to the reduction in the exploitation of non-renewable natural resources by transforming the mining co-product into sustainable sand.
