          Pre-Treatment

          Regardless of the source of the intake water, Veolia technologies ensure there is a consistent supply of water to the facility. ??

          Leach Liquor Filtration

          Veolia’s precoat filtration and vacuum deaeration technologies help gold and silver producers achieve maximum efficiency in their gold and silver recovery operations. By filtering the cyanide leach solution before zinc precipitation, precipitated impurities that could be carried over from the decantation steps are removed.?No more than a trace of oxygen is left, minimizing zinc and cyanide consumption.

          Wastewater Treatment

          Veolia is experienced in helping clients reduce their financial exposure and comply with discharge requirements and stringent environmental regulations.? We understand the unique requirements of mine operations and our worldwide expertise in mine water issues allows us to offer specialized water treatment solutions that treat water and?efficiently remove a wide range of contaminants such as heavy metals, arsenic, suspended solids, organics, iron, manganese, and specific ions.

          Tailings Pond

          Veolia offers a unique combination of water and solid waste treatment capabilities, which enable us to tailor solutions to each mine’s tailings challenge. Veolia ensures overflow compliance and water treatment, but we also look at the overall wastewater strategy. In particular, Veolia investigates opportunities to treat wastewater at source point to reduce the load going to tailings and we see tailings as an opportunity for water and metals recovery to make the most from the available resources.?

          Acid Mine Drainage

          Operating mines, as well as abandoned mine sites, generates acid mine drainage which requires water treatment to prevent adverse impacts to rivers and streams. Veolia has developed a proprietary process known as DenseSludge? to reduce sludge management costs and improve treatment plant operating efficiency. The process utilizes conventional equipment combined with our process expertise in sludge recycle techniques to form a heavier, denser sludge. This solution reduces sludge volume in the clarifier by up to 90% and improves lime utilization, resulting in significant savings.

          Solutions Mining and/or Resource Recovery

          Veolia provides the expertise required for several mining production processes. HPD? evaporation and crystallization systems are often a critical component in evaporites and solution mining, by-product recovery, and internal water process management for the mining industry.

          Services

          Veolia Water Technologies offers a wide range of service options for mines including Aquavista? digital services to monitor your mine water from a distance and mobile water and wastewater treatment solutions to cover emergency, temporary or long-term water treatment needs.

          Focusing on system performance, compliance with process and environmental requirements and long-term cost-effectiveness, we are able to meet the most demanding standards of reliability, safety and quality.

            Case Study - Canadian Gold Mine?

            Technology: Actiflo? and Hydrotech? Discfilter

            Location: British Columbia, Canada

            A leading gold mine producer?needed a wastewater treatment plant to remove Total Suspended Solids (TSS) and some heavy metals from their new gold mine effluent by using as little land space as possible while producing a solid waste.?The permanent effluent treatment system?consisted of several Veolia proprietary technologies which were selected for their robustness and compactness, starting with the Actiflo? high-rate ballasted clarification process for primary metals removal.? The water was further polished by a highly-efficient Hydrotech? Discfilter, which gave added insurance in meeting very stringent discharge criteria. A centrifuge was installed to dewater the sludge. The inlet flow was between 3,200 and 6,000 m3/d.?
