GOLDEN SANDS / Bentonite

Bentonite.

A natural clay-rich material with binding, fluid-control and selected sealing or absorbent applications.

Understanding the mineral

Bentonite is commonly dominated by montmorillonite, a smectite clay mineral. Its composition and preparation influence how the material performs.

Depending on grade and treatment, bentonite can provide binding, viscosity and suspension control, filtration control, swelling and sorption. Representative testing is needed to establish the performance of Golden Sands material.

Assessment priorities

The planned work will assess material properties and application fit. These priorities describe the program, rather than completed laboratory results.

Composition and variability

Assess mineral composition, grade and consistency across representative samples from the three parcels.

Material performance

Test the properties relevant to buyer requirements, including binding, rheology, filtration, swelling or sorption where appropriate.

Processing and qualification

Compare test findings with processor specifications and assess whether milling, classification or activation would improve the product case.

Industrial uses of bentonite.

These are general industry uses of bentonite, not confirmed applications or specifications of Golden Sands material.

Binding applications

Selected bentonite grades are used in foundry moulds and iron-ore pellets. Binding strength, thermal behaviour and consistency help determine qualification.

Drilling & fluid control

Bentonite can provide viscosity, suspension and filtration control in drilling fluids. Performance must be tested against the intended application and specification.

Sealing systems

Selected grades may be suitable for sealing applications. Swelling, permeability and site-specific requirements determine fit.

Absorbent applications

Sorption and other specialist uses depend on mineral composition, preparation and the performance required by the process.

Raw material first.

Golden Sands intends to supply raw bentonite to processors once the material meets their requirements and the supply route is ready. Future supply depends on technical acceptance, applicable approvals, operating readiness and agreed commercial terms.

A focused development route

A staged commercial route.

Raw material first.

Supply raw bentonite to processors once the material meets their requirements and the supply route is ready.

Then, selective processing.

Consider milling, classification or activation when testing, customer requirements and delivered economics support the investment.
