Mining
& Metals
A world-class technical reference for mining engineers, mineral processing plant designers, EPC contractors, procurement heads, and TPI inspection agencies specifying fasteners, wear materials, and corrosion-resistant components for mining and metals applications — covering abrasion-resistant steel grades, heap leach and acid process material selection, the MSHA safety regulatory framework, the critical tailings dam safety topic and the GISTM standard, and the QC and documentation discipline required for mining and metals processing supply.
Wear Environment
& Abrasion-Resistant Steel
Mining and mineral processing present a distinctive materials challenge combining severe mechanical abrasion (from ore, rock, and slurry handling) with, in specific process circuits, highly aggressive acid chemistry — requiring material categories genuinely distinct from most other application references throughout RR Hydraulic’s library.
1.1 — Abrasion-Resistant Steel: AR400 and AR500
Abrasion-resistant (AR) steel plate — most commonly designated by approximate Brinell hardness (AR400 at approximately 360–440 HBW, AR500 at approximately 470–540 HBW) — is a distinct wear-resistant material category widely used across mining and mineral processing equipment for chute liners, crusher wear plates, bucket and dipper edges, and conveyor components subject to severe abrasive wear from ore, rock, and mineral handling. Unlike the general structural carbon steel discussed throughout RR Hydraulic’s other structural references, AR steel is specifically engineered and heat-treated for high hardness and wear resistance rather than optimised for weldability, formability, or general structural ductility — welding and fabrication of AR steel requires specific procedure qualification accounting for its higher hardness and generally lower ductility compared to standard structural steel grades.
1.2 — Slurry and Abrasive Flow Wear
Mineral processing slurry handling — tailings transport, flotation circuit piping, and general ore/concentrate slurry systems — presents a combined abrasive-erosive wear environment distinct from the general process piping applications discussed throughout RR Hydraulic’s other references, where suspended solid particles in the flowing slurry cause progressive erosive wear at pipe walls, elbows, and fittings independent of and in addition to any general corrosion mechanism. Material selection for slurry piping systems balances wear resistance (favouring harder materials or specific wear-resistant linings) against the general corrosion resistance requirements discussed elsewhere in this reference where the slurry carries corrosive process chemistry alongside its abrasive solid content.
1.3 — Acid Mine Drainage and Process Water Chemistry
& MSHA Safety
Regulatory Requirements
Heap leach and other acid-based mineral extraction processes present some of the most aggressive material selection challenges in mining, while the MSHA regulatory framework imposes mining-specific equipment safety requirements distinct from general industrial regulation.

2.1 — Heap Leach and Acid Process Circuit Material Selection
Copper Heap Leach (Sulphuric Acid)
Copper heap leaching uses dilute sulphuric acid solution to extract copper from ore — piping, pumps, and structural components in direct acid contact draw on the same sulphuric acid resistance principles discussed throughout RR Hydraulic’s 904L and Incoloy 825 references, with duplex stainless steel also widely used for the combined acid and chloride resistance many heap leach solutions require.
Gold/Silver Cyanide Leach
Cyanide-based leaching for gold and silver extraction presents a different chemistry profile — generally less aggressive from a pure acid corrosion perspective than sulphuric acid heap leach, but requiring careful material compatibility verification given cyanide’s own specific chemical interactions with certain metals and the process’s typical alkaline pH range.
Smelting and Refining Acid Circuits
Metal refining processes (copper, nickel, and other base metal refining) frequently generate highly concentrated sulphuric or nitric acid process streams as part of the refining chemistry — material selection for these circuits draws on the highest-severity acid resistance materials discussed throughout RR Hydraulic’s Hastelloy C-22/C-276 and specialty alloy references.
2.2 — MSHA: The Mining-Specific Safety Regulatory Framework
2.3 — Governing Standards
AS/NZS 1418 (and Regional Equivalents)
Crane and mining equipment design standards referenced across mining operations in Australia and internationally, alongside the general structural and mechanical standards discussed throughout RR Hydraulic’s other references.
ASTM A514 / A128 (AR Steel Base Standards)
Base ASTM standards frequently referenced alongside manufacturer-specific AR400/AR500 product designations for abrasion-resistant steel plate procurement, discussed in Section 1.1.
GISTM & Critical
Infrastructure Bolting
Tailings storage facilities represent some of the highest- consequence infrastructure in the mining industry — a series of documented, catastrophic historical tailings dam failures has driven the development of a specific, industry-wide safety management standard directly relevant to material and component selection for this critical infrastructure category.
3.1 — Why Tailings Dam Safety Is a Critical Industry Topic
3.2 — Material and Component Considerations for Tailings Infrastructure
Monitoring and Instrumentation Mounting Hardware
Piezometers, inclinometers, and other geotechnical monitoring instrumentation critical to ongoing tailings dam safety assessment require reliable, corrosion-resistant mounting and fastening hardware — given the safety-critical monitoring function these instruments serve, hardware reliability directly supports the facility’s ongoing safety management under the GISTM framework discussed in Section 3.1.
Spillway and Outlet Works Components
Gates, valves, and control structures managing water level and discharge from tailings facilities require reliable, corrosion-resistant materials and fasteners — following similar material selection principles to the hydroelectric gate/spillway hardware discussed in RR Hydraulic’s Power & Energy reference, adapted to the specific tailings water/slurry chemistry.
General Structural and Access Infrastructure
Access walkways, structural support for monitoring equipment, and general tailings facility infrastructure fastening, drawing on the general structural bolting practice discussed throughout RR Hydraulic’s dedicated Structural Bolts, A325, and A490 references, applied with the elevated criticality awareness appropriate to this infrastructure category.
3.3 — Documentation and Traceability for Tailings-Related Supply
Given the safety-critical nature of tailings dam infrastructure and the GISTM framework’s emphasis on rigorous, auditable safety management, material and component supply for this infrastructure category should be documented and certified to the same rigorous standard discussed for other safety-critical applications throughout RR Hydraulic’s references (nuclear, offshore, and aerospace) — complete EN 10204 3.1/3.2 certification, full traceability, and, where the specific project’s safety management system requires it, third-party inspection witness and countersignature.
