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.

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:

  1. Superior cohesion and reduced rebound
  2. Rapid development of green strength and shape stability
  3. Excellent anti-washout properties
  4. 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.
