development) and engineering companies (upscaling and
process implementation).
The proposed processing flow-sheet includes sorting,
gravity and magnetic separation and flotation to recover
Li concentrate to produce battery quality Li hydroxide but
also to target by-product recovery such as Ta, Nb, Sn, W,
quartz and feldspar products for the ceramic industry. The
main challenges for the development of the lithium proj-
ects in Europe is how to accommodate environmental and
social standards to the needs of Li mining projects. Due to
local opposition several European Li projects were halted
(Rio Tinto in Serbia) or delayed (Savannah).
