Dolomite – Its Processing and Application in Iron and ...Jun 28, 2017 · Addition of dolomite through sinter is more preferred route since CO2 of dolomite is driven out during the sintering process. In case of sintering, dolomite is crushed to -3 mm (in the range of 85 % to 90 %) in hammer crushers before mixing it in the sinter mix. In case of direct feed to blast furnace, lump dolomite (10 mm to 30 mm size) is used.

A Process for Sintering of Diopside Prepared from DolomiteDiopside CaMgSi2O6 is an attractive material because of its applications. It was prepared by sintering the mixture at different temperatures (900°C-1300°C). Starting materials were pure SiO2 and dolomite raw materials. In order to improve the properties of sintered samples, such as the density egg white (ovalbemin) has been added into diopside.
