Abstract
Vanadium (V) is a transition metal with a silver-gray color. It is commonly used in high-strength alloys because of its ability to improve impact and abrasion resistance, even when only a small amount is added. In recent years, there has been active research into vanadium reduction-oxidation flow batteries (VRFB), which are suitable for use in the development of storage devices for renewable energy applications. Separation and recovery of vanadium from low-grade stone coal ore is currently being investigated in China. Various pre-treatment processes have been studied, such as magnetic separation and gravity separation, that can be used to treat large quantities of ore, as well as flotation processing based on the surface characteristics of the minerals. There is an urgent need for the development of separation technologies to facilitate the self-sufficient extraction of vanadium resources present in Korea.
