Since there is little difference in density between spodumene and associated gangue minerals, the usual gravity separation methods, such as jigging, spiral beneficiation, and shaking table beneficiation, are unsuitable for separating spodumene ores. However, heavy media or liquid beneficiation is an effective separation method for spodumene ore.
