Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO

Design of Comminution Circuit for Optimum

Designing an efficient and economic mineral processing plant begins with the choice of the best and most economic comminution circuit based on ore properties and concentrate end-user's specifications. This is because crushing and grinding for preparation of suitable feed for the downstream processes are cost intensive. The Itakpe iron ore processing plant presently produces a taiing material containing up to

How to use comminution processes for reducing

There are two types of comminution circuits; open and close circuit. In most cases, we use a combination of them to control the ore size at every stage, then to get a final product with narrow size distribution and less fine particles. Moreover, it is a question of energy consumption, engineering, and circuit optimization. For example, suppose we have an iron ore of 0.5 meters, and the
