TAILINGS MANAGEMENT

​

Zinc

 

By implementing Accelerated Mechanical Consolidation (AMC®), the mine was able to:

​

• Extend TSF lifespan by 3.5 years without raising dams or building new facilities

• Deferred multi-million-dollar capital costs associated with new tailings infrastructure

 

TAILINGS MANAGEMENT

​

Copper

 

When applied to copper Phibion AMC operations can deliver:

​

• 23% increase in dry density; and 

• 415 days added to useful life of asset

 

TAILINGS MANAGEMENT

​

Rare Earth Minerals

 

In just two years following the introduction of Phibion's AMC operation at Mt Weld, Western Australia, the mine reported:

​

• 70% water recovery rate

• 50% reduction in tailings volume

• +40 kPa shear strength

 

TAILINGS MANAGEMENT

​

Bauxite

 

Jamalco adopted Accelerated Mechanical Consolidation (AMC), revolutionizing how bauxite residue is managed. By implementing AMC, Jamalco has:

​

• Reduced newly deposited residue volume by 30%

• Increased final residue density by 20%

• Strengthened deposited residue to >30 kPa

TAILINGS MANAGEMENT

​

Alumina

 

AMC is widely used in the alumina industry. Results from multiple operations have proven that Phibion AMC can deliver:

​

• Shear strength >35 kPa in <42 days from deposition;

• 50% reduction is TSF area; and

• A tailings surface that can be safely accessed and contoured by conventional earthmoving equipment. 

 

TAILINGS MANAGEMENT

​

Phosphate

 

When applied to phosphate tailings these operations deliver:

• Consolidation to very high density <35 days;

• An increase in water recovery >16%; and

• A tailings surface that can be safely accessed and contoured by conventional earthmoving equipment.

 

TAILINGS MANAGEMENT

​

Bauxite

 

When applied to bauxite tailings Phibion AMC operations deliver:

​

• Shear strength >35 kPa in <42 days;

• A 50% reduction in operational footprint; and

• A tailings surface that can be safely accessed and contoured by conventional earthmoving equipment.
