How it Works - Gold Magic

This is the primary classification area - all materials, sand, gravel, etc. (wet or dry) is shoveled into this area. Large size and most low specific gravity materials roll out of the pan as it rotates. Heavy weight materials (gold) sink to the lowest point at the joining of riffle and the pan (1-C) and commence rotating toward areas (2,3,4).

Gold processing - Mining and concentrating | Britannica

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Gold extraction - Wikipedia

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold.
