It's a great way to utilize household items for gold separation and even adds nutrients back into the soil. 7. Using Your Pool Filter. Pool filters contain sand in them, which is used to filter out impurities from the water. If your pool or hot tub has a sand filter, use this sand to separate gold from sand. Just pour the rocks and sand into ...

Our founders, Sutton Steele & Steele, invented the first dry materials separation equipment, known today as "density or gravity separators, air tables or fluidized bed separators". Originally developed and patented in 1919, the density separation is achieved with two components, mechanical vibration and air fluidization.

The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m.

The dry separation technologies have made great progress both in theory and application. Given the lack of comprehensive organizing the literature of density-based dry separation methods, it is difficult to understand the technology development status and prospects. Therefore, the paper has thoroughly summarized the literatures of dry gravity ...

It can also adjust the induction distance between the magnetic disk and the ore particles to get different magnetic field induction intensity, to achieve a one-time separation of many minerals. This equipment is widely used in dry separation of Ilmenite, monazite, and other magnetic and non-magnetic minerals.
