SNC-Lavalin has been awarded an engineering, procurement and construction management (EPCM) contract from NEXA Resources for its majority-owned Aripuanã zinc-copper-lead project in Mato Grosso, Brazil.
The Montreal-based professional services and project management company will deliver EPCM services for the project out of its Belo Horizonte office, in Brazil, and will include all operations required for copper, zinc and lead ore processing, including crushing, grinding, flotation, thickening, filtration and storage of concentrates and tailings, as well as load out of the final concentrated products and all related surface infrastructure, it said. The mandate also includes waste backfill, mine ventilation, and mine dewatering.
The Aripuanã project is an underground polymetallic mine and concentrate processing facility to extract zinc, copper and lead. Once completed, it will have an anticipated mine life of 13 years and a processing capacity of 1.8 Mt/y of ore per year, according to SNC-Lavalin.
The project’s zinc process flowsheet has been developed by considering conventional technologies for treatment, including sequential flotation for the recovery of zinc, copper, and lead as separate concentrates, according to NEXA.
SNC-Lavalin said the project will rely on “data-centric engineering” for development and design, and the use of immersive technologies for training operations personnel.
Work has begun and is slated for completion by the beginning of 2021.
Maria de Lourdes Bahia, General Manager of SNC-Lavalin Brazil, said: “Our Mining & Metallurgy sector has a long history in reimbursable EPCM services, and this award is testament to our continued recognition in this model of project delivery.
“This mandate is well aligned with our services-based strategy for mining and metallurgy projects. We look forward to continuing our trusted relationship with NEXA Resources in the successful execution of the project.”
