Iron ore tailings are industrial solid wastes generated from mineral processing. The disposal of iron ore tailings leads to environmental threat and serious security because of their tiny particle size and large storage. In this paper, suspension magnetization roasting and magnetic separation technology were utilized to recover …

Abstract. Stress annealing is utilized for enhancing the magnetic softness of Fe 83–x Co x B 10 Si 3 C 3 P 1 (x = 0–16) amorphous alloys with saturation polarization up to 1.75 T. All of the stress-annealed alloys exhibit improved soft-magnetic properties, including low coercivity of 1.8–2.2 A/m, low core loss of 0.09–0.11 W/kg at 1.0 T and 50 …

Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Bastnäsite, …

The orbital electron structure of these elements contains many unpaired electrons, which means these rare earth materials can store large amounts of magnetic energy. A neodymium magnet can store about 18 times more magnetic energy than an iron magnet of the same volume. Rare earth magnets are widely used today in many applications, …

The proportion of iron is 100 — (34.8 + 34.8) = 30.4%. Roughly, the ore may be considered as composed of one-third each of copper, sulphur, and iron. This is the commonest ore of copper; but its value depends so much on circumstances other than the percentage of copper contained in it that it is not quoted on the market.

This present paper discusses both the dry and wet magnetic separation techniques used for processing of a low grade siliceous iron ore sample. The investigations carried out on low grade iron ore fines reveal the following: 1. The low grade iron ore fines contain around 45 % Fe, 10.69 % SiO 2 and 12.25 % Al 2 O 3. 2.

The price of iron ore has fluctuated over the last decade, peaking in 2011 and then dropping below $100 per metric ton in 2015. Currently, the commodity sits at around $70-80 per metric ton. This makes iron one of the most affordable metals on Earth [2]. What's more, iron is abundant and easy to extract from its ores.
