Proline Gold Mining and Prospecting Equipment/Gold Dredges

2.5" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other 2.5" dredges were floating on inner tubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline 2.5" dredge sat on sturdy pontoons and used a power jet for dredge vacuum.

Soil Degradation an overview ScienceDirect Topics

Soil Degradation and Rehabilitation. An important criterion of soil degradation is the loss of soil organic matter. Compared with soils in more humid regions, those in warm arid regions tend to be inherently poor in organic matter from the outset, owing to the relatively sparse natural vegetative cover and to the rapid rate of decomposition.

Peru Artisanal Gold Mining (ASGM) Remediation Planning

Artisanal and small scale gold mining (ASGM) is a traditional livelihood in Peru, providing much needed income for many impoverished communities. Currently, the prevailing method of ASGM in the country involves using large amounts of mercury to extract gold. These activities result in the release of tons of mercury each year, causing significant air, soil, and

Suction Dredging for Gold New 49ers Prospecting Club

Using a dredge, an (experienced) operator is able to process a much larger volume of streambed material than with any other small scale hand mining apparatus. Most of the gold bearing river bottom streambed material is sucked up as quickly as the operator is able to feed it into the suction nozzle.Rocks that are too large to pass through the suction nozzle are moved out of the way by hand.

Dry washing for Gold

Sometimes the gold is pounded directly into the caliche and needs to be removed with a pick or crevice tool. Caliche layers which are close to the surface allow small scale dry washing operations to be economically feasible, because of the lesser amount of gravel and material which needs to be shoveled off the gold deposits.
