Now, flotation is a conventional method for sulfur removal in many iron ore processing plants. Also, several researchers promote this method.[21] 4.1. Basics of Iron Ore Desulfurization Using Flotation Flotation can be simultaneously used to remove oxide and sulfidic gangue minerals from the iron ores.
In this research, the samples were collected from the iron concentrate grinding circuit product in the Golgohar pelletizing plant. They were subjected to flotation tests on a laboratory and industrial scale. In addition, the properties of pellets produced before and after desulfurization by flotation were investigated.
