Langtro, the slurry comes down the spirals. Think of them like banks of helter skelters. The light stuff, quartz, gets thrown out to the edge, and the heavy stuff, tungsten, tin and tourmaline, stays on the inside. At the bottom of each spiral there is a “knife” that forces the light stuff out of the system and the heavy stuff in to the shaking tables. The tables have a series of ridges, are irrigated with water and further separate the heavy stuff from any light stuff that get past the spirals,
Very easy to understand, if you are looking at the kit in action!
Very, very cheap. The whole process.
