scandium ore processing

Scandium

Scandium is rare, with only a very small amount of worldwide production per year. It is present in minute quantities in many minerals, notably monazite. However, it is only economical to extract it from uranium ore tailings and from the minerals euxenite, gadolinite and thortveitite. Get price

Experimental Study on Concentrating Scandium by

Based on the benefication of the complex silicate ore containing scandium, the research about aid-leaching agent used in the leaching of the scandium concentrate was been conducted. And the suitable leaching agent and aid-leaching agent which the useful ions entered into leaching liquid and the harmful ions were kept in leaching residue were been found according to the experiment results.

All About Scandium

Over this period the US and Australia produced small amounts of scandium as a byproduct of fluorite, uranium and tungsten ore processing. In the 1980s China began extracting scandium from mine tailings and other existing production streams but I understand that output never exceeded 25-30 kilograms (25-30kg) per year for the two decades or more thereafter.

Platina Resources : Positive DFS for Platina Scandium

The ore will be mined by free-digging strip mining and hauled to the Plant Site near Condobolin. The process plant will be designed to treat high grade scandium ore (limonitic ore) through high pressure acid leaching to produce high purity (min, 99.99%) scandium Get price

scandium ore concentrating

Bauxite ore residue is an alkaline solid waste generated in the alumina production, which enriches approximately 98% of scandium in the bauxite ore (Nguyen et al., 2016, Klauber et al., 2011). The content of scandium in this residue varies from 0.0040 wt% to 0.0100 wt%, depending on the properties of raw bauxite ore and processing technologies. Get price
