How does a small gold dredge work?

Suction dredges utilize a high-pressure gasoline powered water pump to suck up water, gravel and gold, and inject this material into a sluice through a header box. The header box dampens the rush of water and gravel so that it flows evenly into the sluice.

How does gold dredging work?

A suction dredge essentially works like a heavy-duty underwater vacuum cleaner. It sucks up rocks, gravel, silt, and anything else at the bottom of a streambed using a gas-powered pump and suction hose. These materials pass into a floating sluice, which filters and recovers the gold.

What is the purpose of a gold dredge?

A gold dredge is a placer mining machine that extracts gold from sand, gravel, and dirt using water and mechanical methods. The original gold dredges were large, multi-story machines built in the first half of the 1900s.

How does a gold dredge move?

Bucket line dredges are not self-propelled, so they need to be manually anchored in position. This is done using winches and locked in place using a large stake called a spud. Once anchored, the whole dredge and boom is designed to move around to reach all the material in front of it.
