Natural resources in the form of rocks and other geo-materials are one of the most widely used commodities. The building materials industry is a major consumers of raw materials with resources processed such as limestone, gypsum, and clay. These materials get manufactured into products like cement and concrete, screed, bricks, plaster, and dry wall panels (see Figure 1).
The refractories and raw materials suppliers are other relevant industries with a high demand for geological resources. Magnesite is used as source material for linings in blast furnaces and kilns. And as suppliers to the chemical industry, high-purity limestone producers have to apply strict product quality control to meet the demands of their customers. Therefore, the analysis of raw materials is for many industries one of the most important analytical tasks that they perform.
Controlling the grade and quality of the incoming materials before they enter a process gives much higher confidence that the final product will be of the required specification and helps to prolong the life of the equipment used during the process.
