All of the iron and steel plants in Oman are employing either direct reduced iron (DRI) or electric arc furnace (EAF) production processes. The advantage of using the DRI process to transform ore into pig iron, is that it can use either natural gas or coal as a feedstock. DRI smelting is also an attractive choice

Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse …
