Gangue existing states largely affect the high-temperature characteristics of iron ores. Using a micro-sintering method and scanning electron microscopy, the effects of gangue content, gangue type, and gangue size on the assimilation characteristics and fluidity of liquid phase of five different iron ores were analyzed in this study. Next, the …

The manner in which the ore sorting is performed is largely dependent on the metal(s) and ore mineral(s) to be sorted. To date several different technologies have been investigated, including X-ray fluorescence, X-ray transmission, radiometric sorting, and optical sorting (Knapp et al., 2014, Manouchehri, 2003). The economic impact of …

Gangue minerals are distributed in silicates (Quartz), carbonates (dolomite), and oxides (hematite). Because of the diversity of copper-bearing minerals and gangue minerals, considering only one classification criteria is unfeasible; hence, an analysis of the behavior of Tizert ore in response to several technologies was conducted.

Ore sorting is the separation of mineral resources based on economic value, separating rock containing valuable commodities from low-grade waste material. This process allows mining companies to extract the most value by prioritizing high-grade ore for energy-intensive downstream processing while diverting gangue to waste piles early on.

An ore is a mineral from which a metal can be extracted economically and easily on a commercial scale. Example: Bauxite ( Al 2 O 3. 2 H 2 O) and Clay ( Al 2 O 3. 2 SiO 2. 2 H 2 O) are the minerals of Aluminium. Bauxite, on the other hand, is the primary ore of Aluminium. Clay is not suitable for use as an Aluminium ore since it is a Silicate ...
