South ulam

The South Ulam, quarrying operation is located on the southern slope of Mount McCamley, 15 kilometres south south west of Marmor and 60 kilometres from Gladstone on the Central Queensland coast.

South Ulam Calcite Quarry Owned by Omya Australia Pty Ltd

The South Ulam quarrying operation is owned and managed by Omya Australia Pty Ltd, a fully owned subsidiary of Omya AG, the world's

largest producer of ground calcium carbonate. The South Ulam calcite is ground to a stonedust that is used in Queenslands underground coal mines as well as in agricultural lime products. The South Ulam quarry stone is processed at the company's Bajool processing plant.

Calcium carbonite coating pigments and fillers are produced by Omya Australia Pty Ltd with use of the latest technology which is practically fully automated from the mining operation through to the packaging. Despite all the modern technology that is available today, calcium carbonate remains a natural product, therefore, the type of filler produced has specific qualities depending on whether it has been derived from limestone, chalk or marble. This makes the different products suitable for different applications.

South Ulam Calcite is Derived From Marble

Calcite mined from the South Ulam quarry is derived from marble. Calcite is a rock forming mineral found throughout the world in igneous, metamorphic and sedimentary rocks. The properties of calcite make it one of the most widely used minerals in the world as it is commonly used in the construction industry, as well as an abrasive, in the treatment of soil in the agricultural industry, as an aggregate, a pigment, as well as in the pharmaceutical industry and many more.

South Ulam Marble is a Metamorphic Rock

South Ulam marble is a metamorphic rock that is created from limestone after it has been subjected to extreme heat and pressure. The size of the calcite crystals in South Ulam marble has been determined by the amount of metamorphism it had been exposed to. Marble that has been exposed to higher levels of heat and pressure generally have larger calcite crystals than it would have otherwise.

South Ulam Marble Used in Queenland Monuments, Agriculture and Mining

Much of the South Ulam marble has been used as monuments, particularly those built in honour of those who didn't return from the First and Second World Wars. Modern construction uses calcite derived from marble to produce high quality cement and concrete. The crushed product is easily mixed and transported to be made into a slurry that will harden into a durable buliding material. Concrete using calcite marble has been used in the mining industry, the building of highway surfaces, bridges, walls and many other construction uses. Pulverised South Ulam marble is also used as a dietary supplement in animal feed as well as for soil treatment in agriculture.
