Fluorspar meets similar targets in iron foundries, where the load on the kiln is increased by about 7-9 kg per tonne of molten metal. Fluorspar in the cement industry. Fluorspar is used as a melt in cement production. This material is added to the mixture of 网页2012年9月8日 Fluorspar is added to help the combination of the kiln feed into the white cement clinker so reducing the fuel (pet coke) consumption of the kiln. Feldspar is added to correct the alkali:sulphate balance in the kiln. Petcoke is high in sulphur so the feldspar provides additional alkali to balance that. As the feldspar is finer than the raw mill 网页Fluorspar is the predominant commercial source for the chemical element fluorine. Fluorine is a non-metallic element and the lightest of the halogens and therefore largely irreplaceable in its use. There are two principal commercial grades of fluorspar: Metallurgical grade (60-96% CaF2) and acid grade (+97% CaF2). 网页The Asia-Pacific Metallurgical Grade Fluorspar Market is projected to register a CAGR of over 5% during the forecast period (2021-2026).
