Industial Limestone

Carefully crushed and screened to exact industrial specifications, Graded Industrial Limestone provides a consistent, naturally occurring source of calcium and alkalinity. This raw, precision-sized mineral is optimised for applications requiring natural, sustained chemical integration. In wet Flue Gas Desulphurisation systems, its uniform grading ensures peak efficiency as the primary scrubbing agent, capturing SO₂ from exhaust streams and supporting compliance with emissions standards.

Hydrated lime

High-purity alkalinity in a safe, ready-to-use dry powder. Chemically known as calcium hydroxide (Ca(OH)₂), hydrated lime is a dry, easy-to-handle white powder that has already completed the exothermic slaking process at the manufacturing facility, making it significantly safer to handle on-site than quicklime. For acid mine drainage, it rapidly neutralises highly acidic run-off and precipitates dissolved heavy metals, enabling the safe discharge or recycling of mine process water.

Milled Unslaked

The high-surface-area powerhouse for rapid, uniform chemical reactivity. Processed into a highly refined powder, Milled Unslaked Lime maximises exposed surface area to deliver immediate and exceptionally efficient chemical integration, engineered for systems that demand accelerated slaking rates and aggressive, uniform pH adjustment. For acid mine drainage, its high surface area drives rapid neutralisation of highly acidic run-off and efficient precipitation of dissolved heavy metals, minimising reagent consumption.

SSS Hydrated Agricultural Lime

Recovered from the highly reactive, fine particulates of the calcination kiln and thoroughly slaked, SSS Hydrated Agricultural Lime transforms industrial kiln dust into a highly valuable, eco-friendly resource, delivering a slow-release infusion of essential calcium and trace minerals. For landfill applications, its cementitious properties stabilise contaminated soils and sludges, securely fixating heavy metals for safe, long-term containment.
