Vibrating Screen

For efficient wet or dry screening—Hi-capacity, 2-bearing design. Flywheel weights counterbalance eccentric shaft giving a “true-circle” motion to screen. Spring suspensions carry the weight. Bearings support only weight of shaft. Screen is free to “float” and follow positive screening motion without power-consuming friction losses. Saves up to 50% HP over 4- bearing types. Sizes 1 x 2′ to 6′ x 14′,

Direct Lithium Extraction (DLE)

Direct Lithium Extraction (DLE) is an innovative method of extracting lithium from brine or other lithium-rich sources without the need for traditional evaporation ponds. Unlike conventional lithium extraction processes, which rely on the natural evaporation of water to concentrate lithium, DLE techniques offer a more efficient and environmentally friendly approach. The traditional lithium extraction process involves pumping lithium-rich brine into

Outcrops

In the examination of an undeveloped prospect a decision must be arrived at from an inspection of the outcrops and the exposures in a few shallow pits. Prospects that are offered for sale rarely expose any important quantity of good ore, work having usually been stopped when the immediate exploration no longer yielded favorable results. It should be borne in
