Hazard Assessment of Ores and Concentrates - ScienceDirect

2018-1-1  This chapter will therefore focus on hazard assessment. Further assessment aspects are discussed in Chapter 7. 10.2. Substance Identity. A correct identification of the ore or concentrate is a first and essential step for its hazard identification and classification (see Chapter 7 for a worked example). Ores and concentrates are more complex ...

Characterisation and magnetic concentration of an iron

2019-1-1  Based on the ore characteristics (e.g. particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and high-field) and inverse cationic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.

A Life Cycle Assessment (LCA) study of iron ore mining

2019-9-24  Iron ore is extracted from Alegria mines, with average grade of 43%. The final product, iron ore concentrate, exclusively dedicated for export (34 customers in 25 countries) is delivered through its own sea terminal in the city of Anchieta-ES-Brazil. The concentrate is transported to the port through two iron ore pipelines 400 km long.

2013-12-24  The rate of reduction of both iron ore and quartz varies (Figures 1 to 3). Quartz dissipates easily, breaking down to fines with little applied stress. Though the hardness value of quartz (i.e. 7 on the Mohr’s scale) is a bit higher than the iron ore (Hematite (5.5-6.5), Magnetite (5.5-6), it is far more brittle than iron ore (Gribble, 1988).
