What the heck is limonite?

Ocher is the softer limonite used as a pigment. Some limonite is used as iron ore. "Minette" refers to an oolitic form of limonite that is the major iron ore in Lorraine and Luxembourg. "Bog iron ore" refers to masses of limonite deposited in swampy conditions. In fact, the name "limonite" comes from the Greek meaning "meadow".

Iron Ore Pelletization

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore. Separation techniques such as ...
