Mining Applications for Acti-Gel® 208
MINING OVERVIEW
Acti-Gel® 208 additive provides superior particle suspension, stabilizes mixtures, and dramatically improves the workability, flowability, pumpability and performance of high solids formulas.
- Uses include Slurry Pipelines, Tailings, Backfill, Mine Seals and Shotcrete applications.
- Helps build the carrier fluid preventing coarse particles from riding on the bottom of the pipe.
- Enables increased flow rates and lower pressure loss.
- Reduced frictional losses = reduced pipe wear.
- Not affected by attrition, abrasion, high shear, grinding, pH or salt concentration.
- Works in water-based systems at any salinity/pH level with the presence of high solids.
- Improved flowability = prevent / eliminate blockages
- Increased Solids = enables higher solids slurry / improves profitability
- Reduced Pressure Loss
We can show how Acti-Gel 208 additive can save you money and increase the solids of your slurries.
Applications
MINE BACKFILL
MINE BACKFILL
Acti-Gel® 208 thixotropic material suspends particles, reduces segregation, and dramatically stabilizes mine backfill. During mixing or emplacement flow is greatly enhanced due to its shear-thinning behavior.
This allows solids to be increased significantly and binder levels to be reduced. Acti-Gel 208 additive continues to suspend particles under flow, which prevents segregation, reduces abrasion and eliminates blocking.
Benefits:
- Reduces binder usage to give cost savings
- Allows increased solids
- Improves flowability
- Maximize safe-pumping distance
- Reduced plugging potential
- Stabilizes paste fill mix designs
- Reduced cycle time
- Unaffected by water quality, pH or temperature
- Reduced abrasion
- Environmentally friendly

MINE SEALS
MINE SEALS
Acti-Gel® 208 thixotropic material suspends particles, reduces segregation, and dramatically stabilizes concretes. During mixing or emplacement flow is greatly enhanced due to its shear-thinning behavior.
On removal of shear, the rate of thixotropic rebuilding of the lattice structure is exceptionally fast, which provides:
- Superior cohesion and reduced rebound
- Rapid development of green strength and shape stability
- Excellent anti-washout properties
- Reduction in hydrostatic pressure
When used in an optimized mix design, Acti-Gel 208 product has been shown to increase green strength, decrease rapid chloride permeability, and reduce efflorescence – all with outstanding stability and compaction.
Some designs may result in a reduction in measured slump.
Acti-Gel 208 additive complies with ASTM C 494, Type S.
Acti-Gel 208 additive complies with AS 1478-2000 Type SN.

HIGH PERFORMANCE SHOTCRETE
HIGH PERFORMANCE SHOTCRETE
- Acti-Gel® 208 low-dose rheology modifier and anti-settling agent stabilizes mixtures, provides superior aggregate suspension, and dramatically improves the performance of sprayed concrete for mining operations.
- Acti-Gel 208 additive promotes a cohesive concrete that stabilizes nearly the instant energy is removed from the pumping system.
- This is perfect for high performance shotcrete where high lifts, thick walls, and one-pass overhead applications are desired.
Reduces Shotcrete Costs:
- Decreases rebound
- Reduces/eliminates silica fume
- Reduces dosage of nozzle accelerators up to 50%
- Increase application thickness up to 100% in a single pass
Increases Quality and Workability:
- Reduces airborne particles when spraying
- Improves adhesion, cohesion and compaction to achieve higher lifts
- Sprays concrete without sagging or sloughing
- Reduces time to reach 1MPa (145psi)
- Improves re-entry times in underground applications
- Allows lower quality aggregates and manufactured sands to be utilized
- Improves and extends workability
- Reduces /eliminates efflorescence

SLURRY
SLURRY
Acti-Gel® 208 thixotropic material suspends particles, reduces segregation, and dramatically stabilizes high solids slurries. During mixing and transport, flow is greatly enhanced due to Acti-Gel 208 additive’s shear-thinning behavior.
On removal of shear, the rate of thixotropic rebuilding of the lattice structure is exceptionally fast, which prevents i) particles from dropping out of suspension ii) eliminates hard-packing, and iii) facilitates safe and easy start-ups, even after periods of extended shutdown.
Benefits:
- Improves flowability and settling properties
- Enables higher solids slurry
- Minimizes plugging potential; safe and easy start-ups
- Reduces water consumption and down time
- Decreases erosion and corrosion effects
- Reduces pressure loss along the pipe line; increases flow rate

TAILINGS
TAILINGS
Acti-Gel® 208 thixotropic material suspends particles, reduces segregation, and dramatically stabilizes high solids slurries. During mixing and transport, flow is greatly enhanced due to Acti-Gel 208 additive’s shear-thinning behavior. After the tailings are deposited in the tailings dam, Acti-Gel 208 additive prevents segregation which enables better particle packing, denser beds, and improved water recovery.
Benefits:
- Improves flowability and settling properties
- Enables higher solids slurry
- Minimizes plugging; safe and easy start-ups
- Reduces water consumption and down time
- Decreases erosion and corrosion effects
- Reduces pressure loss along the pipe line; increases flow rate.
