Value of mineral deposits associated with mafic and ultramafic
1. Introduction. Magmatic ore deposits associated with ultramafic to mafic magmatism (MODUM) are important contributors to current global mineral production and an essential source of several strategic, industrial metals including copper, nickel, cobalt, platinum-group elements (PGE), chromium, titanium and vanadium (e.g., United States @article{Wang2020ScandiumOD, title={Scandium: Ore deposits, the pivotal role of magmatic enrichment and future exploration}, author={Zhenchao Wang and Martin Yan Hei Li and Ze Liu and Mei‐Fu Its beneficiation from various primary and secondary sources is currently being studied under several research and development Scandium: Ore deposits, the pivotal role of magmatic enrichment

Scandium is classified as a critical raw material by the European Union. Its beneficiation from various primary and secondary sources is currently being studied under several research and development projects. Due to the geochemical characteristics of Sc, its enrichment to ore grades by geological processes is scarce. Potential new sources are Ore Geol. Rev. 62, 72–128 (2014).

Environmental impacts of scandium oxide production from
The rare earths tailings as raw materials directly not only eliminate the stage of raw ores beneficiation but also make the production process simple and efficient. Moreover, many by-products (i.e. Fe concentrate, REs concentrate, S concentrate, Nb concentrate, and fluorite coarse ore) are produced during the scandium oxide production.In niobium ores, scandium content can vary from 0.022 − 0.032 wt% (Brazil) to 0.057 wt% (Tomtor). Table 3 shows the scandium content, leaching parameters, and extraction efficiency of studies found in the literature review. Scandium concentration, as presented, varied from 40 ppm (Fe-Ti residue) to 2.1 wt% (U-REE).Recovery of scandium from various sources: A critical review

Scandium is usually produced from the by-products of Ni, Al, Ti, REE and Zr ore beneficiation, with the majority of current production arising from the tailings of Bayan Obo Fe-REE mine (EiluThe ore deposits at Sudbury were formed by the segregation and settling of dense immiscible sulfide from a melt sheet generated by a catastrophic impact event at 1.85 Ga (Keays and Lightfoot, 2004). The mineralization is localized in ore bodies related to the outer contact of the SIC in association with the Sublayer and Offset Dykes (Souch et al., Mafic intrusions in the footwall of the Sudbury Igneous Complex:

Processes Free Full-Text Recovering Scandium from Scandium
Beneficiation, hydrometallurgy, precipitation method, extraction method, and ion exchange method are the main process of recovering scandium from primary ores, slag, and waste liquid [8,9,10,11]. At present, the main objects of scandium recovery in primary ores are phosphorite, some rare earth ores, mica ores, brown yttrium niobium Scandium is a soft and silver-white transition metal. Its distribution is highly dispersed distribution and it has no independent minerals [1, 2].So, it mainly occurs in other minerals in the form of isomorphism or ion adsorption, such as vanadium titano-magnetite, apatite, red mud etc. [3, 4].At present, the only independent ore mine is the Experimental Study of Pre-concentration from Silicate Springer

Metallurgical processes for scandium recovery from various resources
Based on the analysis of chemical composition and the phase of scandium-containing clay type rare earth ore in a place in China, it is found that the content of scandium in the ore is 18.55 g/t.Therefore, ore beneficiation does not have much role in the processing route. As these deposits occur in the weathered profile, so the open-cast mining methods are adopted. This mined product does not require any further milling and is directly subjected to leaching with sodium chloride or ammonium chloride solution, which results in 90% Mineral Processing of Rare Earth Ores SpringerLink

Recovery of scandium from silicate minerals by high-pressure
This study investigated the leaching of scandium from a Sc-bearing silicate ore. The Sc concentrate obtained by beneficiation pre-enrichment has 1.03 × 10 −4 wt% Sc and 14.66 wt% Fe. The main Sc-bearing minerals are limonite, chlorite, sericite, and hornblende, in the form of isomorphism.This study was carried out to develop a beneficiation process flowsheet for the recovery and separation of thorium from Choghart iron mining waste. The characterization and mineralogical studies showed that the mining waste comprised ThO2:2100 ppm, and the main thorium-containing mineral was thorite.

The proven and probable ores reserves at Owendale are estimated to be 4.02 million tonnes (Mt) at a cut-off grade of 450 parts per million (ppm) of scandium. The mine is estimated to contain 3,512t of scandium, 3,599t of cobalt, and Some researchers have tried to increase the concentration of scandium in the bauxite residue by physical beneficiation before leaching . Both are rich in scandium, iron, and aluminum. Therefore, the process developed for scandium ore can be applied to bauxite residue.
