Iron ore : mineralogy, processing and environmental by Liming Lu

By Liming Lu

Iron Ore: Mineralogy, Processing and Environmental matters summarizes contemporary, key study at the characterization of iron ores, together with vital themes reminiscent of beneficiation (separation and refining), agglomeration (e.g., construction of pellets or powders), blast furnace expertise for smelting, and environmental concerns in relation to its creation.

The textual content is a perfect reference at the subject in the course of a time whilst iron ore construction has elevated considerably, pushed by means of expanding call for from international locations similar to India and China.

  • Provides a entire assessment of the worldwide iron ore undefined, exploring its features and characterization
  • Expert research of caliber requisites for iron construction, iron ore agglomeration applied sciences, environmental concerns, and low-emission technologies
  • Timely textual content to accompany the elevated iron ore construction happening in constructing international locations like India and China

The ore at these operations is mined at 30–40% Fe and beneficiated using gravity separation, especially spirals, and magnetic separation as required.

In addition to the iron ore operations in Michigan and Minnesota, the historic Iron Mountain mine in southwestern Utah was reopened in 2010 after being closed for more than 10 years. The mine is owned and operated by CML Metals Corporation and is located near the northern fringes of the Mojave Desert. The ore is mined at about 47% Fe and then crushed and ground to about 150 μm to liberate the magnetite, which is recovered using magnetic separation followed by reverse flotation to reduce the silica content.

However, production from the mine has been declining in recent years and was around 5 Mt in 2012. The new Khumani mine is located about 60 km north of the Beeshoek mine adjacent to Kumba Iron Ore's Sishen mine and produced about 10 Mt in 2012. The Khumani mine is quite cost-competitive due to the low stripping ratio and the reported quality is among the best in South Africa. Both Kumba Iron Ore and Assmang's iron ore products are railed to Saldanha for export through Transnet's rail system. Stockpiling and loading at Saldanha are also handled by Transnet with South African exports of iron ore totaling about 48 Mt in 2013.
