Industrial Minerals: Products

Limestone can be defined as a Calcium-Carbonate (formula Ca(CO3)), which is utilized extensively in metallurgical, industrial and agricultural applications, and as a construction aggregate.

Metallurgical grade limestone is a source of calcium (CaO) utilized as a fluxing agent in iron and steel making, and ferrochrome production. It is also used in glass-making, paint-manufacturing, in decorative applications, in water-treatment and flue-gas desulphurization.

Limestone is suitable for use as a construction aggregate.

  • Most limestone is made into crushed stone that is used in road base, railroad ballast, foundation stone, drainfields, concrete aggregate, and other construction uses.
  • Powdered limestone is used as a filler in paper, paint, rubber, and plastics.
  • Crushed limestone is used as a filter stone in on-site sewage disposal systems.
  • Powdered limestone is also used as a sorbent (a substance that absorbs pollutants) at many coal-burning facilities.

Our Products Include

  • Agricultural Lime Dolomitic
    Aglime. Soil enhancer.
  • Animal Hygiene Lime
    BioLim Animal Hygiene Lime. White hydrated lime specifically made for animal hygiene control. Fine white to off-white powder. This hygienic and eco-friendly product creates a stable alkali environment which inhibits bacterial growth, improves biosecurity, reduces odours and prevents the spread of contagious disease.
  • Hydrated Lime
    Road lime for soil stabilisation. SABS 824 approved soil stabilisation lime is an effective way to modify soils in order to improve workability and load-bearing characteristics by increasing stability of natural soils.
  • Unslaked Lime

Dolomite can be defined as a Calcium-Magnesium-Carbonate (formula CaMg(CO3)2), which is utilized extensively in metallurgical applications, and as a construction aggregate.

Metallurgical grade dolomite, with less than 3% silica content (SiO2), is a source of magnesium ore (MgO) utilized as a fluxing agent in iron and steel making, and ferrochrome production.

As a construction aggregate, dolomite has an impressively low water demand, allowing for cement savings in concrete applications. It is also used as a road base material, an aggregate in concrete and asphalt, a railroad ballast, fill-material, and in the production of bricks, blocks, and lintels, etc.

Burnt dolomite is mainly used as metallurgical aggregate in steel production. (Source)

Calcite is the principal constituent of limestone and marble. It is used as a construction material, abrasive, agricultural soil treatment, construction aggregate, pigment, pharmaceutical and more. (Source)
