  • Miller Table - for fine gold recovery (SOLD OUT)

    Miller Table Operation: the design of our water table concentrator or "miller Table" is similar to a traditional sluice box, but it operates entirely without riffles using a very thin layer of low velocity water. Our special matting has just enough "tooth" (roughness) to grab onto the fine gold while allowing the metered smooth, laminar water flow to release the lighter weight sands.
