Micronised Minerals Fine Quicklime is a high quality calcium oxide product manufactured to a very fine grain size (typically less than 150μm), maximising the availability of CaO for chemical processes.

Quicklime or Burnt Lime chemically known as Calcium Oxide (CaO), is a highly reactive chemical with variety of uses in the mining, industrial water treatment sectors as well as Civil sector. Quicklime is most commonly used for its ability to stabilise pH, soften water, stabilise bio-solids, and precipitate nutrients.

Quicklime for Mining sector

Quicklime is mainly used by mining industry to treat runoff and process waters from coal mining, metal mining and non-metal mines. Quicklime used with properly designed slaking plants helps to neutralise acids from mining waters and precipitate metals and non-metals. 

Micronised Minerals has supplied individual clients up to 20,000 tonnes per annum of Quicklime utilising in-house designed innovative Handling and Storage Solutions.

Quicklime for Civil sector

Quicklime has important applications in construction operations. It can be used for Road/Soil stabilisation; dry-up wet soil at construction sites and improve soil-workability and short-term strength.

Road / Soil Stabilisation – When adequate quantities of Quicklime and water are added, the pH of the soil quickly increases to above 10.5 which enables the clay particles to break down. The chemical reaction forms cementitious products that forms the matrix that contribute to the strength of lime-stabilised soil layers. The matrix is permanent, durable and significantly impermeable, producing a structural layer that is both strong and flexible.
