Iron Ore & Pellets

Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron ore pellets are to be used as raw material for blast furnaces.

Limestone

Limestone has numerous uses: as a building material, as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints.

Silica Sand

Silica sand is the most commonly used sand because of its great abundance.It is made by either crushing sandstone or taken from natural occurring locations.

Clinker & Cement

Cement manufacturers purchasing clinker usually grind it as an addition to their own clinker at their cement plants. They also ship clinker to grinding plants in areas where cement-making raw materials are not available.

Products - Dolomite


Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate CaMg(CO3)2. The word dolomite is also used to describe the sedimentary carbonate rock, which is composed predominantly of the mineral dolomite.

Dolomite is used as an ornamental stone, a concrete aggregate, a source of magnesium oxide and in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals such as lead, zinc, and copper. Where calcite limestone is uncommon or too costly, dolomite is sometimes used in its place as a flux for the smelting of iron and steel. Large quantities of processed dolomite are used in the production of float glass.

In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source. Home and container gardening are common examples of this use.

Dolomite is also used as the substrate in marine (saltwater) aquariums to help buffer changes in pH of the water.

Particle physics researchers like to build particle detectors under layers of dolomite to enable the detectors to detect the highest possible number of exotic particles. Because dolomite contains relatively minor quantities of radioactive materials, it can insulate against interference from cosmic rays without adding to background radiation levels.

Dolomite is a popular choice for Motorcycle speedway tracks throughout Australia and New Zealand.
