MAXIMISING WATER RESOURCES EFFICIENTLY

The mining industry is heavily reliant on water for the extraction of valuable raw materials but more than ever before, the global community is looking to the industry to play their part in water stewardship. A shortage of fresh, clean water is said to be the greatest threat of the next decade, presenting risks to societies and economies across the world. With the global population increasing to 8.5 billion people by 2030, the World Economic forum anticipates a water shortfall of 40%.

With mines being heavily reliant on this important resource in their operations, the industry has a substantial impact on local watersheds. How does an industry that consumes water every day contribute to conserving this precious resource? Simply put, the industry needs prioritise sustainability. Effectively managing water shortages presents opportunities to play a leadership role in water catchments and also mitigate the risk of operational disruptions.

DRA has been working with clients such as Anglo American, South 32, Exxaro, Managem, Newmont, Kropz Elandsfontein, Barrick, and Glencore, as well as public works, to deliver world-class water treatment solutions that combine process technology, design engineering and project management capabilities to create a better future for all.

The transition to a water less or waterless mine of the future requires a shift in roles within the industry. Smarter, more courageous strategies that embrace technology, automation and digitization will drive innovation and lower cost and productivity pressures, ultimately creating real, sustainable value for communities around the world. Our team of team of highly skilled engineers, scientists and project managers work with each client to provide an ideal, customised solution to meet unique project needs. We have an opportunity to drive water solutions forward and we can help you to change your operations today that build opportunities for tomorrow.

How DRA can help make a difference for your project

WATER FOOTPRINT REDUCTION

WATER FOOTPRINT REDUCTION

Increasing water scarcity, growing population, climate change and extreme weather conditions, together with stricter water regulations, decline in ore grade and increasing controversy on water use between mining operations and local communities, effective governance of shared water resources and protecting water quality is an economic imperative and social responsibility for mining companies.

DRA Water’s reduces client water requirements through innovative water management strategies. These strategies reduce the volume of water required by operational processes, the dependence on freshwater resources and the negative effects of water shortages.

ESG SCENARIO MODELLING

ESG SCENARIO MODELLING

The physical impacts of climate change are becoming more significant and have the potential to be extremely costly. With their locations fixed, assets themselves may be at risk of suffering significant damage costs from climate change impacts. More so, operations are often energy-intensive to build and run. 

DRA Water’s scenario modelling enables investors and asset owners to evaluate both transition and physical climate-related impacts in their portfolios.

LEGACY ENVIRONMENTAL LIABILITY

LEGACY ENVIRONMENTAL LIABILITY

Smart environmental and social choices translate to improved business performance and an enhanced market position for the long term. Our clients have seen these positive impacts, too. Our team of specialists invest in understanding your business drivers and unique culture.

This combination of expertise and client investment consistently yields the best possible results and highest levels of client satisfaction. We have helped clients address environmental, health, safety, and sustainability challenges with fit-for-purpose solutions.

Mining's Watershed Stewardship Opportunity

Mining by nature is an interaction with what is naturally underground, so for the mining industry the "invisible" is what we experience every day - including the confluence of the natural hydrogeology and manmade infrastructure (mines).

THE MINING INDUSTRY NEEDS TO GET AHEAD OF THIS CURVE.

WATER WASTE TO WATER WISE

The World Economic Forum1 is predicting a shortage of clean, fresh water as the greatest global, societal, and economic risk over the next decade. Mining as an industry is renowned for its heavy reliance on water, but on the other side of that gold coin – the industry is also a vital entity of the global supply chain. Ultimately, we’re all reliant on the industry, in one form or another.

Mine Water Treatment 

IS YOUR MINE WASTE BEING MINIMISED AND CONVERTED TO USEFUL END PRODUCTS?

The experienced team of experts manages all aspects of mine water treatment with unique solutions for neutralization, reclamation, waste minimisation and conversion to useful end products including process reuse or potable standards.

DRA combines water strategy with life of mine water, mass, and salt balances for supply side and demand side management, resulting in reduced water consumption, maximized reuse, and sustainably manage of water resources.

 

 

 

 

WATER MANAGEMENT & USAGE OPTIMISATION

OPTIMISE WATER USAGE ACROSS THE OPERATIONS LIFE OF YOUR ASSETS

DRA Global’s services include overall water management to produce holistic solutions from source identification, to treatment and operational water balance optimisation.

Our industry-specific process engineers and water treatment specialists generate and optimise water usage across the operating life of our clients’ assets.

 

 

 

 

BRINE MANAGEMENT & REDUCTION

DRA has the engineering capability and implementation experience to recover valuable by-products and additional product water from saline or brine streams.

Brine reduction includes the ability to concentrate unrecovered water and reduce storage requirements with focus on net cost savings. Concentration of unrecovered water subsequently decreases legacy civil and environmental liabilities for our clients.

FEATURED PROJECTS

background

EWRP Brine Treatment Plant

The project aims to deliver a 2,000 m³/day brine treatment plant. The brine to be treated is a supersaturated calcium, sodium sulphate effluent and is treated through the DRA calcium softening reactor-clarifier and a multi-barrier UF, high pressure RO system to produce a product water that complies with the discharge specification set out by the resource water objective for Nooupoort Spruit.

TWEEFONTEIN WATER RECLAMATION PLANT

DRA Global was contracted by Glencore to provide zero liquid discharge (ZLD) for their operation at Tweefontein. With extensive experience in mine water reclamation and ZLD applications, DRA Nexus has constructed a 15,000 m³/ day water reclamation plant comprising of a 2-stage membrane process with inter-stage softening.


background

KLIPSPRUIT WATER TREATMENT PLANT

DRA was appointed by Seriti Power to design, construct and commission a 2 ML/D mine water reclamation plant at the Klipspruit Mining Operations. A turnkey solution was required to treat  the mine impacted water to achieve a treated water specification fit for environmental discharge at the highest water recovery.
