Abstract The characteristics of the vanadium-bearing stone coal during chlorination roasting at different temperature were investigated. Chlorination roasting could promote the breakage of the structure of the main vanadium-bearing minerals, such as muscovite and illite, in the stone coal and more than 90% of the vanadium was lost after the sample was roasted in chlorine at 1000 °C for 1 h.

This study determined the optimal conditions required to obtain maximum vanadium extraction and examined the transition of mineral phases and vanadium speciation during the bioleaching process. Parameters including the initial pH value, initial Fe 2+ concentration, solid load, and inoculum quantity were examined. The results revealed that 48.92wt% of the vanadium was extracted through ...

Salt Lake Brines. Lithium is present on Earth in brines and minerals, but only in low concentrations. There are some 230 billion tons of lithium dissolved in the sea, and it is present in the Earth's crust at between 20 to 70 parts per million by weight—mainly in igneous rocks such as granite. New sources, e.g., clays like hectorite, are rare.
