How does a sluicing machine work?
Sluice boxes work by essentially creating a straight, consistent channel, with regularly spaced slow spots created by riffles. Each riffle creates an eddy, a backflow of water that allows the gold to settle out. Material is placed at the top of the box and carried in suspension down the channel.

What is sluicing in mining?
method of placer mining Ground sluicing is a special technique for the mining of natural placers as well as artificial ones (tailings piles, for example). A natural flow of water is used to disintegrate and then transport the material through a sluice, where the valuable mineral is concentrated.
How does a gold sluice work?
Sluice boxes are designed to mimic this naturally occurring gravity separation. As water carries gold-laden sediment through the box, small obstructions called riffles block the free flow of material. These tiny flow restrictions form low pressure pockets where the gold collects.
What are the tools that early miners used?
Traditional mining, also known as old-school mining, is a mining method involving the use of simple manual tools, such as shovels, pickaxes, hammers, chisels and pans.
What equipment is needed for underground mining?
Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material.
What equipment is used in underground mining?
What is sluicing in gold rush?
Sluicing was the use of running water to break down gold-bearing earth, and a sluice box was used to recover the gold.
