Mining

Water is a critical resource for mining operations, particularly in Saudi Arabia’s arid regions, where scarcity demands efficient water reuse strategies. Danat Saudia provides comprehensive water management solutions to help mining companies optimize their water use, treat process wastewater, and minimize environmental impact. Our filtration and separation systems remove heavy metals, suspended solids, and dissolved contaminants, allowing safe discharge or reuse in operations. We support tailings water treatment, ensuring compliance with environmental regulations while reducing reliance on freshwater sources. By implementing closed-loop water recycling systems, we help mining operators lower costs, improve sustainability, and maintain responsible water stewardship.

Applications & Case Studies - Mining

    • Danat Saudia have solutions for wash oil treatment to recover water that can then be used for dust suppression or other purposes at site

    • Treatment is done using MYCELX REGEN and polishers that reduces the creation of waste and enables the recovery of oil

    • Solutions have been deployed in Australia at Rio Tinto sites and trials are underway at South African mines currently

    • Danat Saudia provides solutions for pit dewatering treatment, enabling recovered water to be safely reused on site for dust suppression, process water, or general operations, reducing reliance on freshwater sources.

    • Treatment is achieved through staged solids removal and polishing technologies, allowing suspended solids, hydrocarbons, and dissolved contaminants to be reduced to reuse or discharge specifications while minimising secondary waste generation.

    • These solutions are well suited to variable flow and water quality conditions, which are typical of pit dewatering operations across different stages of mine development.

    • Systems have been deployed and trialled across multiple mining jurisdictions, supporting both permanent installations and mobile treatment for changing pit geometries and mine plans.

    • Danat Saudia can treat Tailings Water to remove residual hydrocarbons and process oils, preventing surface oil films from forming on tailings ponds and reclaim dams.

    • Improved evaporation reduces the volume of water requiring active recovery or treatment, easing pressure on reclaim pumping systems and lowering overall water management costs.

    • Ability to remove the heavy metals and treatment for acid bearing sulphides helps to ensure environmental regulations

    • Trial work at several African mining sites

    • Temperature control is critical for process stability – overheating in circuits, exchangers, or storage systems can reduce recovery rates in mining and compromise product quality or safety in industrial plants.

    • Chillers protect equipment and prevent unplanned shutdowns – maintaining cooling during peak loads, heat waves, or equipment failures avoids damage to pumps, compressors, and heat-sensitive units.

    • Production can be maintained or increased during constraints – temporary or supplemental chilling allows operations to run at nameplate capacity even when permanent cooling systems are overloaded or offline.

    • Essential for safety-critical and turnaround scenarios – chillers and cooling towers provide controlled cooling during maintenance, emergency response, and restart phases where heat buildup poses operational or personnel risks.

    • Rapid deployment without capital expenditure – through Danat Saudia’s partnership with the world’s largest global rental fleet of chillers and cooling towers, cooling capacity can be mobilised quickly without long lead times or permanent infrastructure.

    • 8 successful projects in both petrochemical and waste management facilities

    • Currently undertaking trials on upstream applications for TOC with Oil Majors

    • Have successfully reduced TOC levels from 5000ppm down to <40ppm

    • Ground water can be extremely complex due to cross contamination underground between neighbouring facilities

    • Danat Saudia’s ability to treat multiple types of contamination in a sequential and cost effective manner has been highly effective at 4 sites in Jubail where we have successfully treated ground water

    • Treatment can be at any desired flowrate upto 150m3/hr but geotechnical analysis should be done before requesting flowrates about 10-15m3/hr to protect for any subsidence

    • Presence of Mercury can lead to embrittlement of plant infrastructure

    • Mercury can be present in both Aerosolised as well as Aqueous Form

    • Conventional technology is often unable to remove aerosolised form of mercury and it can overwhelm treatment systems

    • Mersep technology is able to reduce aerosolised mercury significantly and retrofit existing systems

    • Inlet water to an RO system can contain trace hydrocarbons that will foul membranes

    • Given the high flowrates that RO system often operate at any fouling can impact performance significantly

    • Our solution is not only able to reduce fouling, it can help trace the source of hydrocarbon contamination reaching the RO
