Additionally, iron ore processing facilities often receive ores from various sources (such as satellite pits) with different qualities. These ores may be treated by different processing routes and/or blended to meet product specifications. Some examples of different iron ore crushing and screening flowsheets are provided below: 8.2.3.1.Gravity separation has also been used in combination with flotation at many REE processing operations throughout China [25, 93]. The froth flotation process has been used on Pea Ridge iron ore’s tailings to concentrate the REEs .

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 Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation.

In India, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 10-25 % of the total iron ore mined, amounting to 18 million tons per year (Das et al., 2000 ). The tailings contain silica in high percentage (40-60 %, from various locations). This makes it a suitable raw material for theTurning to iron ore exports and imports, the tonnages are summarized in Table 1.1 for 2012 and 2018 (Australian Department of Industry, Science, Energy and Resources, 2021; US Geological Survey, 2020; United National Conference on Trade and Development (UNCTAD), 2021).As shown in Fig. 1.3, China is the largest iron ore Introduction: Overview of the global iron ore industry
