3.1.1 Group 1 mining and beneficiation as a single stage. Most of the studies considered beneficiation altogether with the mining operation. For example, Awuah-Offei and Adekpedjou carried out a review scrutinising the very first LCAs applied to the mining sector.This work is focused on the extraction stage, and it mentions the Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as Beneficiation of Magnetically Separated Iron

Opportunities Mineral Processing
The main physical separation processes used in dry process ore beneficiation are those based on particle size, density, magnetic properties and electrostatic charge. Among the current projects in Brazil is that of Centaurus Metals, who are also planning to install a dry beneficiation line with magnetic separators at their Jambreiro Iron OreTherefore, a flowsheet for mixed ore enrichment was introduced, covering separation into fractions with increased share of sandstone and dolomite-shale ore and subsequent enrichment in separate lines [9]. A block diagram of mixed ore beneficiation processed in the Rudna area is shown in Fig. 4 [10]. Figure 4.Technology of Polish copper ore beneficiation

The beneficiation of lithium minerals from hard rock ores: A
In many lithium ore beneficiation plants, it is a common practice to de-slime the ore prior to flotation. De-sliming is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de-sliming isOur solutions for on-line analysis (elemental and mineralogical) directly in the mine enable ore sorting and fast counteractions on changing iron ore composition to produce the optimal blend for downstream processing. This saves mining operations multiple millions in USD every month since iron ore beneficiation increases significantly the costsIron Ore Analysis & Process Optimization Solutions
