The beneficiation of lithium minerals from hard rock ores
There are two economic sources of lithium; brines and hard rock ores. The majority of the global lithium production, greater than 60%, is produced from brines while lithium ores accounted for the remaining production (Ebensperger et al., 2005).Table 1 summarises the world’s major lithium producers from ores and brines, and the total reserves. The lithium production in Chile and Argentina is

Crushing Ore for Gold Veins
Once the ore has been broken up into fine dust, testing for free gold content in hardrock ore can be done using some type of gravity method. A simple gold pan can be used to sample small amounts of crushed ore, or if a decent water supply is available then it can be run through many types of separation devices. Shaker tables are commonly used, and although quite expensive, work exceedingly

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

The mineshafts and drifts were then “mucked out” and the gold-bearing ore was transported to the surface for processing. To access the gold, the ore had to be crushed. The first crushing equipment was the Mexican arrastra, a device that ground the ore between two stone slabs rotated by a mule or humans.

Gold sometimes occurs as a lode deposit in small amounts in rock, known as gold ore. Gold can also be found in alluvial deposits known as placer deposits, as flakes, grains, or nuggets. Ore, a naturally occurring rock or sediment with enough minerals, must be considered economically important enough to extricate. Ores can be either metals or gems.
