Venezuela's sole iron ore producer, Ferrominera Orinoco, produced 12 million mt of iron ore in 2015, or 86% of its initial plan for the year. No figures of the first half of 2016 were disclosed. The company plans to expand its annual iron ore production capacity to 40 million mt from the current 25 million mt within the next three or four years as a consequence of planned railway construction.

Ore Beneficiation - an overview ScienceDirect Topics

Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include i. Dephosphorization. ii. Desulfurization. iii. Desiliconization. iv.

Channel-iron deposits - Wikipedia

The water content of channel iron deposits (quoted as Loss on Ignition) is from 7% to 12%, which is the highest of all iron ore types, generally due to the presence of goethite-limonite. Phosphorus, aluminium and sulfur levels are another concern, typically being above normal levels in-situ although if the phosphorus and aluminium are hosted in a weak cement, they can often be washed out during

Supplies from domestic mines are mainly relatively low-quality ore requiring beneficiation (a process used to improve the quality), but this incurs great costs.

Iron Ore - 1st Edition

Iron Ore: Mineralogy, Processing and Environmental Issues summarizes recent, key research on the characterization of iron ores, including important topics such as beneficiation (separation and refining), agglomeration (e.g., production of pellets or powders), blast furnace technology for smelting, and environmental issues relating to its production.

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, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron
