Ore Beneficiation an overview ScienceDirect Topics
Crushing and screening is typically the first step of iron ore beneficiation processes. In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock.In addition, large amounts of tailings were produced in the beneficiation process of low-grade iron ore, which has caused severe environmental problems, such as land occupation, reclamation, and water pollution [23,24,25]. Thus, it is essential to develop novel technologies to achieve the comprehensive utilization of low-grade iron ore resources.Novel Technology for Comprehensive Utilization of Low-Grade Iron Ore

Optimal Recovery of Iron Values from a Low Grade Iron Ore
A low grade iron ore containing 51.6% Fe, 17.6% SiO2, 4.3% Al2O3, and 3.8% LOI was subjected to reduction roasting followed by low intensity magnetic separation studies.At the current rate of GDP growth, this demand will increase and reach up to 300 MT by 2030. Yet, India’s per capita consumption would reach only 160–180 kg (currently approximately 69 kg), which will be lower than the current global average of 208 kg. Hence, to meet the growing steel demand, the demand for iron ore is also increasing.Iron ore beneficiation: an overview ScienceDirect
