> Transformation for a sustainable future
Delivering Cost Efficiency
Water, waste and energy, especially in remote parts of the globe represent a substantial portion of a Mine’s expenses. Energy can even account for over 30% of operating costs. By working to improve the operation and maintenance performance of their environmental assets, Mining companies can significantly reduce their costs.
Improving yield to support competitiveness
Managing cost efficiency and competitiveness is further challenged by depleting ore grades and less accessible deposits. It now takes more to extract the same amount of minerals. But the industry can boost sites’ output by innovating and leveraging on new technologies. Better waste management in particular, such as the reprocessing of tailings, enables to efficiently recover by-products.
Securing the license to operate
Faced with stricter regulatory environment and increased public pressure, Mining companies are under strain to obtain and maintain their license to operate, and develop long-term strategies to reduce their risk exposure. By minimizing pollution, demonstrating environmental responsibility and improving cooperation with local communities, they can secure their project’s uptime and acceptance.
Responsibly planning for Closure
Miners’ responsibility extends beyond operations, leading them to anticipate closure plans. Rehabilitation measures need to be implemented to minimize environmental legacy left to future generations. It calls for better practices today to reduce the remediation cost of tomorrow, but also requires Miners to find innovative partners able to engage with communities and invent solutions giving a second life to their site.
> Veolia's solutions for the mining industry

> Dedicated technologies for the mining industry
• HPD® evaporation and crystallization
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.
• Systems for evaporites mining, coproducts extraction & refining
• Alumina spent liquor evaporation and oxalate removal
• Nickel, lithium, magnesium and zinc salts crystallization
• Vanadium, tungsten, molybdenum and copper crystallized products
• ACTIFLO® – high rate and compact clarifier
The ACTIFLO® technology is a compact process that operates with microsand as a seed for floc formation. The microsand provides surface area that enhances flocculation and acts as a ballast to form robust and rapidly settling floc.
The unique characteristics allow for clarifier designs with high flow rates, short retention times and minimal sludge presence within the unit.
• Footprint 5 times smaller than classic lamella clarifiers or dissolved air flotation (DAF)
• Up to 20 times smaller than conventional clarification designs
DenseSludge™ reduces the cost of water treatment and sludge management in Acid Mine Drainage treatment systems. The DenseSludge™ process can use conventional equipment or Veolia’s Multiflo™ technology to employ sludge recirculation techniques based on Veolia’s process expertise. These techniques form a denser, heavier sludge with lower water content than conventional processes.
• Reduces sludge volume in clarifier by 90%
• Minimizes lime usage and cost
• Minimizes calcium sulfate (gypsum) and calcium carbonate (calcite) scaling
• Provides consistent pH control
• Automated Industrial Cleaning
When cleaning an industrial site, automated robotic cleaning is a safer, more cost-effective and time-efficient solution, minimizing personnel exposure by eliminating or reducing the need for manned entry.
Veolia sets the path in tailoring cleaning and maintenance planning, equipment and security protocols for its Mining customers, in particular for tank cleaning and high pressure water jetting of the various heavy machineries used on a Mine site.
Our customized solutions keep your downtime to the lowest while minimizing the environmental impacts and safety risks of cleaning tasks.

Each year, Veolia helps its Customer recover valuable copper to boost the Mine’s production and alleviate the future environmental legacy of tailing ponds.
3 million m3 per year - installed capacity to process the acid drainage of a closed tailing pond
In a water-positive environment subject to highly seasonal rainfall, Veolia enables a gold mine in Ghana to manage its process wastewater and tailings to meet the local Environmental Protection Agency discharge requirements.
By upgrading the wastewater treatment plant, reviewing operations practices and training a dedicated local team of 23 employees, Veolia allowed its Customer to resume operations and continuously treat the wastewater containing cyanide, a typical challenge for gold mines.
The successful partnership relies on the trust and transparency between the parties which are the key to continuous, safe and reliable operations supporting the Mine’s uptime.

1,600,000 m3/year of wastewater treated
One of Veolia’s solutions consisted in installing a tri-generation plant improving the efficiency of supply, all in line with the Miner’s requirements, which leave no room for error. Electricity distribution reaches 530 GWh, heating 165 GWh and 2.5 million Nm3 of compressed air are distributed daily. Veolia also provides air-conditioning for the mine shaft reaching an underground depth of 1,050 meters and supplying 91 GWh of cold.
Working with Veolia enables the Customer to make the most of its energy assets: residual heat is reused on-site and sold to third parties. Equipment modernization delivered savings on energy consumption equivalent to an annual reduction of CO2 emissions by 50,000 tons.
