At low pH and high chromium concentrations, Cr 2 O 7 2− predominates while at a pH greater than 6.5, Cr(IV) exists in the form of CrO 4 2−. Cr(III) is classified as a hard acid and forms relatively strong complexes with oxygen and donor ligands. Chromium(VI) compounds are more toxic than Cr(III) due to their high water solubility and mobility.

The clinker is next ground to cement (perhaps after a drying stage). Here Calcium sulfate is added to the control set, in the form of a high-purity grade of gypsum or anhydrite. Ceramic grinding media is preferred in the case of white cement grinding in place of high chrome grinding media for avoiding the detoriation of cement whiteness.

Abstract. In order to minimise the environmental, social and economic impacts caused by the mining activity, this work proposes the use of iron ore tailings from tailings dams (IOT) as pigment in the production of a paint for buildings – the Sustainable Paint. The waste originates from the mining activity in the state of Minas Gerais.
Steel-slag with alkalinity greater than 1.8 is usually recommended. 2. Steel-slag can be used to produce energy-saving cement by co-grinding with OPC clinker and blastfurnace slag. In such preparations OPC clinker is about 15-30%, steel-slag around 30-40% and blastfurnace slag is around 40-50%. 3.
