There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
The i350 is a family member of the Falcon Gravity Concentrators Gold Mining Equipment which has revolutionizing the world of alluvial gold mining and dredging the same way its little brother, the i150, has impacted the world of hard rock mining.. This is a gravimetric mineral concentrator that uses enhanced gravity (G''s) to concentrate the ''free'' heavy minerals.
