Iron Ore Pelletizing Process: An Overview

The iron ore pelletizing process consists of three main steps: 1. Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2.

homogenization of the ore as well. The grinding plant is composed primarily of grinding mills 10 and classifiers 11. The grinding process in the flowsheet is followed by a series of separation of specific minerals. In the present flowsheet, flotation plays the main role in separation (or concentration). In

Determination of iron by thiocyanate colorimetry

Method Preparation of Fe3+ standard solutions NB: It may take several days to dissolve the Fe3+ salt used here, so carry out this preparation well in advance of the rest of the experiment. Weigh out about 3.0 g of ferric ammonium sulfate (FeNH 4 (SO 4) 2 •12H 2 O). Use a mortar and pestle to grind the salt to a fine powder.
