Suction Gold Dredge Basics
The riffles and carpet are removed and all material (concentrates) in the box washed into a tub and panned out with a simple gold pan. Larger dredges may employ gold wheels or other devices to aid in the cleanup of the concentrates. The diagram below shows a basic suction dredge flowchart. The foot valve is a one way valve with a screen.
The Metal Casting Operation
When manufacturing by metal casting, pouring refers to the process by which the molten metal is delivered into the mold. It involves its flow through the gating system and into the main cavity (casting itself). Goal: Metal must flow into all regions of the mold, particularly the casting's main cavity, before solidifying.
