Scandium Scandium International Mining Corporation

This makes scandium generally more abundant than lead, mercury, and precious metals. Despite this fairly common occurrence, scandium rarely concentrates in nature. It does not selectively combine with the common ore-forming anions, so time and geologic forces only rarely form scandium concentrations over 100 ppm. There is currently no dedicated

Environmental impacts of scandium oxide production from

10/10/2020· During the scandium oxide production, the beneficiation stage contributes around 88% of the overall impact 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. After the allocation of potential environmental impact according to the properties of by-products, the impact

Scandium Wikipedia

Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present in most of the deposits of rare-earth and uranium

Scandium speciation in a world-class lateritic deposit

23/11/2016· Scandium is often associated with the rare earth elements (REE). The ionic radius of Sc 3+ is slightly smaller than those of heavy REE for the same coordination number. During lateritic weathering of ultramafic–mafic rocks, Sc behaves like the heavy REE. The enrichment factor of Sc between the ore and fresh saprolite is ca. 5 (Table S-5, Fig

Processes Free Full-Text Recovering Scandium from

It is very important to recover scandium from primary ore, analyze the physicochemical properties of main scandium bearing minerals, select reasonable beneficiation methods to find out the trend of scandium and produce scandium concentrate [12,13,14,15,16]. The recovery of scandium from slag mainly refers to the leaching and extraction of scandium from some smelting slag of ferrotungsten

Production Process of Scandium Oxide TRUNNANO

Scandium concentrate (mainly scandium concentrate from vanadium-titanium magnetite beneficiation). The vanadium-titanium magnetite contains Sc 27g/t, and the scandium concentrate obtained after beneficiation contains Sc 112-114g/t. The scandium concentrate is dissolved in hydrochloric acid to obtain a ScCl3 solution, which is used as a raw material for extracting scandium oxide.

US5035365A Thortveitite ore beneficiation process

A thorteveitite ore beneficiation process which comprises comminuting the ore by wet autogenuous grinding to substantially liberate the thortveitite contained therein, and passing the comminuted ore through a nonuniform magnetic field to produce a concentrate and a tailing, the concentrate containing a substantially greater percentage of thortveitite than the ore.

IOP Conference Series: Earth and Environmental Science

The beneficiation process flow of the scandium-bearing rare earth ore in Yunnan Province The separating effect of shaking table used in this scandium-bearing silicate ore was emphatically discussed in this paper. The sample used in shaking table separation was obtained from high-intensity magnetic separation, which the content of scandium, iron, and titanium was 71.3 g/t, 19.21 wt%, and 10.74

Characterization and Pre-concentration of Scandium in

Based on the sample's composition, particle size distribution and the occurrence state of scandium, studies were conducted of the pre-concentration of scandium oxide from the low-grade magnetite ore. From the results of these experiments, a beneficiation process was developed and validated based on low-intensity magnetic separation for iron recovery and high-intensity magnetic separation for

Development and modification of Scandium production

The focus of this project is to develop a material and cost-efficient process to extract scandium from the recently discovered Kiviniemi mafic intrusion, which is a primary scandium occurrence with estimated 13.4 Mt @ 163 ppm Sc. Based on the geochemical characteristics of scandium, its enrichment to ore grades by geological processes is scarce. Consequently, the estimated global scandium
