Mining Dust Suppression
Industrial Misting Solutions For Mining, Quarries & Construction
PortaMist controls dust
Airborne dust is one of the most serious hazards in mining, quarrying and construction. It affects worker health, reduces site visibility, causes regulatory violations and damages equipment. PortaMist's fine mist technology tackles dust at the source — capturing airborne particles before they spread, without disrupting operations.
Dust suppression is not optional — it is a legal compliance requirement under the Mine Health and Safety Act (Act 29 of 1996) for all South African mining operations. Failure to implement adequate dust control exposes mine operators to prosecution, operational shutdown and significant liability. PortaMist provides fully documented, compliant dust suppression systems that satisfy DMR inspection requirements and protect your operation, your workers and your licence to operate.
We design, supply and install dust suppression and water filtration systems for open-pit mines, underground operations, quarries, crushing plants, conveyor transfer points, load-out areas and construction sites across South Africa and into the African continent. Our systems are fully exportable and we welcome enquiries from mining operations anywhere in Africa and internationally. Every system is engineered to the specific demands of your site, regardless of location.
Our Mining Solutions
Dust Suppression
Ultra-fine mist particles bond with airborne dust, causing it to settle harmlessly before it spreads. Effective across crushing zones, haul roads, conveyor transfer points, load-out areas and stockpiles. Continuous 24/7 operation without disrupting mine productivity.
Water Filtration
Multi-stage filtration systems that clean and manage process water continuously. Significantly reduces mains water consumption — critical in water-scarce mining regions across South Africa and Africa. Field-replaceable cartridges mean minimal maintenance and zero downtime.
Integrated Systems
Combined dust suppression and water management in a single system — featuring our zero waste design where all system dumps and bypass water loop back into the tank, meaning nothing is wasted from the system itself. Designed for operations that need both active dust control and full water accountability. Custom engineered to your site layout, dust load and operational cycle.
Application Areas
Open-Pit Mining
Gold, coal, diamond, platinum and iron ore operations generate enormous dust loads. Mobile and fixed misting arrays cover haul roads, blasting zones and stockpile areas with precision — keeping dust within boundaries and workers safe.
Underground Mining
Underground environments concentrate dust to dangerous levels with no natural dispersal. The Mine Health and Safety Act makes dust suppression a legal requirement — not optional. PortaMist systems are engineered for confined underground conditions, controlling respirable dust at the face, haulage ways and ore passes without adding excessive moisture to the environment.
Quarries
Stone, sand and aggregate quarries produce silica dust — one of the most hazardous types. Our misting systems suppress particles at crusher discharge points, screening areas and access roads, protecting workers and surrounding communities.
Construction Sites
Large civil and infrastructure projects face strict dust control requirements, especially in urban environments. PortaMist mobile units deploy rapidly and relocate as the project moves. No permanent infrastructure needed — plug in and control dust immediately.
African & International Mining
PortaMist systems are fully exportable, containerisable and designed to operate in remote locations with minimal infrastructure — making them ideal for mining operations across the African continent and internationally.
Whether you are a multinational mining house, a junior miner or a mining contractor operating anywhere in Africa or internationally — we can design, supply and commission the right dust suppression and water filtration solution for your operation. We welcome enquiries from Zimbabwe, Zambia, Botswana, Mozambique, Tanzania, Malawi and beyond. Contact us to discuss your location and requirements.
General Mining Supplies
Nozzles & Fittings
Industrial-grade stainless steel misting nozzles, push-lock fittings, high-pressure tubing and manifolds. Designed for harsh mining environments — resistant to dust, vibration and temperature extremes. Available for supply and delivery across South Africa and into Africa.
Pump Systems
High-pressure misting pumps sized for mining-scale applications. Single-phase and three-phase options. Automated control modules manage misting cycles, pressure regulation and dry-run protection — fully integrated or standalone configurations available.
Filter Cartridges
Multi-stage sediment, particulate and chemical filter cartridges for mining water filtration systems. Field-replaceable in under 10 minutes. Available in single units and bulk supply for ongoing operational requirements across your site or multiple operations.
Why PortaMist For Mining
Worker Safety
Reduce airborne silica and coal dust exposure at source — the leading cause of occupational lung disease in mining. Active suppression protects workers where it matters most, not just at the face mask level.
Environmental Compliance
Meet NEMA, DMR and local municipality air quality standards. Avoid fines, operational shutdowns and community complaints with active, demonstrable dust control systems that show real-time results. PortaMist systems are designed to keep your operation running without regulatory interruption.
Water Conservation
Fine mist uses a fraction of the water used by conventional dust suppression sprays — making it inherently more efficient and cost-effective. This is especially critical for operations in water-stressed regions or those operating under strict water use licences, where every litre counts.
Rapid Deployment
No civil works or permanent piping required for mobile units. Deploy to any active dust zone in under an hour and relocate as your extraction point moves. Ideal for contractors and operations that need flexible dust control without fixed infrastructure investment.
PortaMist systems are fully exportable and containerisable, designed to operate effectively in remote locations with minimal supporting infrastructure — making them well suited for mining operations across Africa and internationally. We welcome enquiries from operators anywhere on the continent.
