Mining & Mineral Processing FRP Applications — Slurry Piping & Walkways
Heavy-duty abrasion-resistant slurry pipelines, solvent-extraction electrowinning (SX-EW) launders, flotation cell liners, non-corrosive walkway grating, and composite friction rock bolts for underground and open-pit mining.
Mining composite installations demand heavy Class D loading (AS 3996), slip resistance per AS 1657 and AS/NZS 4663, and thick ceramic-bead or vinyl ester abrasion liners.
Where composites fit in Mining & Mineral Processing
Mining processing circuits subject fluid handling systems to severe acid leaching (pH 1.0 sulphuric acid), abrasive mineral ore slurry velocity (3 to 5 m/s), and high outdoor ultraviolet exposure. Traditional rubber-lined carbon steel pipes and galvanized steel grating corrode rapidly when acidic mists attack weld seams. Fiber reinforced polymer (FRP) and glass reinforced polymer (GRP) components formulated with silicon carbide abrasion liners and novolac vinyl ester resins deliver decades of continuous service without costly unplanned plant shutdowns.
Slurry abrasion: measure wear before choosing a liner
Slurry wear depends on particle size, hardness and shape, solids concentration, velocity and impingement angle, so a generic 'abrasion-resistant' claim means little. ASTM G75 measures the abrasivity of a slurry (Miller number) and the relative response of a material to that slurry (SAR number), which is useful for ranking liner materials against the actual ore. FRP slurry pipes use sacrificial inner liners filled with silicon carbide or ceramic particles in vinyl ester or novolac vinyl ester; alternatives include polyurethane or rubber linings and basalt or ceramic tiles in steel. Bends and reducers wear first, so specify thicker liners or replaceable spools there and ask for pipe-loop or field wear data at a similar velocity.
Where GFRP rock bolts fit underground
GFRP rock bolts are used mainly where the ground will later be cut — coal ribs, temporary walls and tunnel faces — because continuous miners and roadheaders cut through them without damaging picks or creating sparks. They are also non-corroding and non-conductive. They are generally not the choice for rockburst-prone hard-rock ground, where yielding steel bolts designed to absorb dynamic energy are used. Anchorage capacity is verified with pull tests (ASTM D4435) in the actual strata, using the resin cartridges and installation method planned for the job, and nuts and plates are checked separately because they often limit capacity.

Abrasive Slurry & Tailings Pipe
Filament-wound vinyl ester pipe with high-density ceramic bead or silicon carbide interior wear liners handling tailings and ore slurries.
Wear-liner material and thickness (thicker at bends), structural wall design to ASTM D2996 or ISO 10639/ISO 10467 as applicable, pressure class including surge, joint type and axial restraint, hydrostatic test pressure, and UV protection for surface lines.
Heavy-Duty Mine Access Grating & Walkways
Molded and pultruded heavy-duty grating panels with coarse silicon carbide grit providing high slip resistance and Class D vehicle wheel loading.
Load table for the actual span and wheel or point loads, AS 1657 compliance for platforms and walkways in Australia (OSHA or ISO 14122 elsewhere), slip-resistance classification (AS 4586 for new surfaces, AS 4663 for surfaces in service), fire-retardant resin where required, and fixing clips suitable for vibration.
SX-EW Solvent Extraction Launders & Tanks
Contact-molded and winding process vessels resisting hot acidic copper/nickel electrolytes, organic kerosene diluents, and acid mists.
A resin system proven in the specific electrolyte, organic phase, temperature and concentration; conductive layers and earthing for static control in solvent-extraction areas; structural stiffeners and nozzles; and fabrication to a recognized standard such as ASME RTP-1 or EN 13121, with inspection records.
Service conditions and applicable standards
Mining equipment operates in harsh wet slurry conditions containing 10% to 50% solids by weight, high concentrations of sulfuric/hydrochloric acids, copper/gold extraction solvents, heavy vehicle wheel traffic, and extreme abrasive mechanical wear.
Chemical-resistance immersion testing
ASTM C581 exposes resin or laminate coupons to the service chemical at the service temperature and tracks hardness, flexural strength and appearance over months. For SX-EW circuits the test medium should be the actual electrolyte and organic phase (extractant plus kerosene diluent), not a generic sulfuric-acid solution, because the organic phase attacks some resins that tolerate acid. Ask the fabricator which resin grade was selected, from which entry in the resin maker's corrosion guide, and whether coupons or field references confirm it.
Fire, smoke and toxicity underground
Materials used underground must limit flame spread, smoke and toxic gases, and requirements differ by jurisdiction — MSHA acceptance in the United States, the MA safety mark with flame-retardant and anti-static requirements in Chinese coal mines, and mine-owner specifications elsewhere. Halogenated flame retardants reduce flammability but increase toxic and corrosive combustion gases, so specify both flame and smoke/toxicity limits and require test reports for the exact laminate.

Buying checks before you send an RFQ
Protect quality, freeze test acceptance boundaries, and prevent material substitutions before commercial commitment.
- Verify Australian AS 1657 walkway design compliance and AS 4663 Class P5 slip-resistance grit certification for wet mine environments.
- Require chemical immersion coupon test data (ASTM C581) proving resin compatibility with the specific acid and organic solvent blend.
- Ensure heavy-duty molded grating is tested for Class D vehicle wheel loading when deployed around maintenance access routes.
- Inspect slurry pipe interior wear liners to confirm homogeneous dispersion of ceramic beads without resin-rich soft zones.
Acceptance evidence to request
For solvent-extraction tanks, launders and piping, require the static-control design — conductive inner layer or carbon veil, earthing points and continuity — and the measured resistance to earth for each item, checked against the project's static-electricity specification (IEC TS 60079-32-1 gives guidance on limits). Include resin batch records and ASME RTP-1 or EN 13121 inspection documentation in the handover package.
Buyer FAQ
Australian mines experience extreme heat, saline groundwater, and corrosive acid leaching mists that destroy galvanized steel walkways in 2 to 4 years. FRP grating complies fully with AS 1657, provides high slip resistance (AS/NZS 4586 R13), and lasts 25+ years without corrosion.
Specialized slurry pipes feature an inner wear liner (3 mm to 10 mm thick) formulated with silicon carbide, alumina ceramic beads, or high-modulus polyurethane embedded in tough vinyl ester resin, resisting particulate impingement erosion.
Yes, using premium chlorendic or novolac vinyl ester resins (such as Derakane 470) provides resistance to both hot sulfuric acid and aromatic kerosene diluents used in solvent extraction circuits.
Composite rock bolts provide high tensile rock reinforcement but can be cut through easily by roadheaders and continuous miners without damaging cutter bits or creating fire sparks.
