Jun 30, 2020· Steel production consumes the vast majority of iron ore produced around the world. To make steel, firms start by crushing and preprocessing ore before smelting it to free the trapped metal with a heat and chemical reaction. This can be used to make socalled "pig iron," solid blocks of iron that can be further processed.
Valueinuse Iron ore is a nonfungible commodity, and its quality varies. To help facilitate price adjustment for differences between expected and delivered product specifications, PRAs have developed valueinuse (VIU) indices for the key priceaffecting chemical components of iron ore iron, silica, alumina and phosphorus.
The capitalintensive cement industry needs to secure valuable deposits over the long term. Close geographical links between cement production and mining sites is also extremely important. Short routes for supply of raw materials take pressure off of traffic volumes and reduce transportrelated emission of pollutants.
