Scandium resources and status of scandium extraction and recycling technology

Scandium belongs to the rare earth element, properties of scandium and its compounds is excellent and be widely used in lighting, alloys, ceramics and many other industries. Our resources are very rich in scandium, reserves ranking first in the world. However, much scandium associated with other minerals, rare independent mineral, extraction difficult and expensive, study on the extraction of scandium and deep processing is still relatively weak, have a big gap with Russia. This paper summarizes the scandium resource profile and its use, review scandium extraction methods and examples of different scandium-containing material depend on the three types of different properties scandium-containing material. According mention scandium process status and progress made dressing and smelting joint is the future direction of scandium recycling technology development; hydrometallurgical process to find efficient aid infusion, improve the leaching efficiency and reduce drug consumption; to find more resources and more scandium recycling methods; recovery of other valuable elements integrated; extend the industrial chain, and strive to develop the deep processing of scandium, increase value-added of products.
