Abrasive Mining Slurry — Equipment Material Selection

Name: Abrasive Mining Slurry Equipment Material Selection Dataset
Creator: James Riggins

Direct answer: This page collects every published row in the LibertyCES datasets that applies to abrasive mining slurry service: hydrometallurgical duty-class selection, engineering rules. Abrasive slurry is a duty class, not a single chemical, so there is no chemical-compatibility chart for it. Everything below is equipment-selection data: vendor-sourced duty-class verdicts and the engineering rules fired on this duty. LibertyCES supplies the equipment for handling these fluids, never the fluid itself.

Hydrometallurgical Duty-Class Material Selection

Service context	Fluid	Concentration	Max temp (°F)	Equipment	Material	Verdict
Leach-circuit slurry transfer, general	Abrasive Leach Slurry	n/a	—	Pump	Centrifugal (any material)	Not Recommended
Leach-circuit slurry transfer, general	Abrasive Leach Slurry	n/a	—	Pump	Electric diaphragm pump (Graco QUANTM)	Recommended
Abrasive slurry isolation / shutoff	Abrasive Leach Slurry	n/a	—	Valve	Knife gate valve (AVCO 6100 Series, 304SS/316SS/Hastelloy)	Recommended
Abrasive, solids-bearing leach solution transfer/dosing	Leach Solution (acid or cyanide)	n/a	—	Pump	Peristaltic / hose pump (Graco SoloTech or ProMinent DULCOFLEX), CSM/Hypalon hose	Recommended
Light dewatering / dirty water only (SG ~1.05)	Light Slurry	SG ~1.05	—	Pump	Schurco P Series	Recommended for light slurry only, Not Recommended for heavy slurry
Combined corrosive + abrasive leach-circuit brine slurry	Leach Circuit Brine Slurry	n/a	—	Strainer	Glass Ceramic Matrix Composite (Fluidtrol)	Recommended

Leach-circuit slurry transfer, general — Centrifugal (any material): Centrifugal pumps fail via seal degradation in abrasive slurry service, regardless of wetted material. (Source: existing rule abrasive-slurry-no-centrifugal)
Leach-circuit slurry transfer, general — Electric diaphragm pump (Graco QUANTM): Seal-less, self-priming, runs dry, removes the failure mode that kills centrifugal pumps in this duty. (Source: existing rule abrasive-slurry-no-centrifugal)
Abrasive slurry isolation / shutoff — Knife gate valve (AVCO 6100 Series, 304SS/316SS/Hastelloy): Beveled, polished/lapped gate specifically engineered to cut through solids and seal tighter when closed. Meets MSS-SP-81 and TAPPI TIS 405-8. (Source: AVCO Valve (avco-valve-mining.md))
Abrasive, solids-bearing leach solution transfer/dosing — Peristaltic / hose pump (Graco SoloTech or ProMinent DULCOFLEX), CSM/Hypalon hose: Hose-only wetted path -- no check valves, seals, or glands in the fluid path -- the correct architecture for abrasive, solids-bearing streams. Two independent roster vendors now confirm this architecture. (Source: Graco (existing case study); ProMinent (prominent-mining.md))
Light dewatering / dirty water only (SG ~1.05) — Schurco P Series: Explicitly NOT a general heavy-slurry pump despite sharing the Schurco family name -- a real design/duty mismatch if misapplied. (Source: existing rule schurco-p-series-light-slurry-only)
Combined corrosive + abrasive leach-circuit brine slurry — Glass Ceramic Matrix Composite (Fluidtrol): Seamless-cast fiberglass/ceramic/vinyl ester matrix engineered for the case where a fluid is simultaneously corrosive AND abrasive -- PVDF solves corrosion, not abrasion; hardened alloys solve abrasion, not broad chemical resistance. (Source: existing rule combined-corrosion-abrasion-glass-ceramic-strainer)

Engineering Rules That Apply

Abrasive Slurry No Centrifugal

Centrifugal pumps fail via seal degradation in abrasive slurry service; electric diaphragm pumps remove that failure mode.

Confidence: confirmed. Source: data/case-studies/mining-slurry-pump.md.

Peristaltic For Abrasive Leach Streams

Peristaltic (hose) pumps wet only the hose — no check valves, no seals, no glands in the fluid path — which is the correct architecture for abrasive, solids-bearing leach streams, extending the existing abrasive-slurry-no-centrifugal and crystallizing-slurry-no-valves-seals rules with a second, independent roster vendor confirmation specific to leach-circuit duty. Graco SoloTech is already the roster's confirmed peristaltic line (real lime-slurry case study on file); ProMinent's DULCOFLEX line (captured 2026-09-10, prominent-mining.md) is a second, independent confirmation of the identical hose-only architecture, named by ProMinent specifically on its dedicated mining/heap-leaching and solvent-extraction pages. Specify CSM/Hypalon hose, not generic EPDM, for concentrated acid or caustic leach solution contact.

Confidence: confirmed. Source: data/vendor-sources/prominent-mining.md, data/case-studies/solotech-lime-slurry.md.

Knife Gate For Slurry Isolation

AVCO's 6100 Series (2"-24", ANSI Class 150, 304SS/316SS/Hastelloy body/shim) is purpose-engineered for solids-laden/slurry isolation: gates are polished and lapped on both sides with a machined bevel on the bottom edge specifically to cut through solids and seal tighter when closed, and the seat is mechanically locked into the body via a stainless retainer ring rather than a molded-in seal. Meets MSS-SP-81 and TAPPI TIS 405-8. This is the real isolation/shutoff-valve pairing for a slurry line already using AVCO's abrasive-tolerant ball valves or a Schurco Slurry pump — a mechanical-geometry answer to the same abrasive-solids hazard the existing abrasive-slurry-no-centrifugal rule addresses on the pump side.

Confidence: single-vendor. Source: data/vendor-sources/avco-valve-mining.md.

Schurco P Series Light Slurry Only

Schurco's own P Series page states its double-volute/thrust-reduction design is specifically for dirty water and light slurries of roughly 1.05 specific gravity - a narrow real design parameter distinct from the general heavy-slurry S/L/Z Series in the same product family. P Series's real advantage (single pumps achieving heads over 50% higher than standard slurry pumps) only holds within that light-slurry envelope; applying it to a genuinely heavy/abrasive slurry job would be a family mismatch even though it's marketed alongside the heavy-duty lines.

Confidence: confirmed. Source: vendor-sources/schurco-slurry.md.

Combined Corrosion Abrasion Glass Ceramic Strainer

Fluidtrol's Glass Ceramic Matrix Composite basket strainer is a seamless-cast fiberglass/ceramic/vinyl ester matrix explicitly engineered for fluid systems that are BOTH corrosive and abrasive simultaneously (seawater, scrubber discharge, and similar challenging systems) - a combined-hazard case that most single-purpose materials in this project's existing rules don't address (e.g. PVDF solves corrosion but not abrasion; hardened alloys solve abrasion but not broad chemical resistance). Custom-built to order (vertical or horizontal large basket strainer configurations), ASME Sec X / PS15-69 standard. Relevant to mining/mineral-processing brine slurries and marine/seawater scrubber applications where this project's existing abrasive-slurry guidance (mining-slurry-pump.md) doesn't fully address chemical corrosivity, or vice versa.

Confidence: single-vendor. Source: data/vendor-sources/fluidtrol.md.
