The Hydraulic Classifier is made in 2, 4, 6, and 8 compartments with two sizes of compartments, namely 4″x 4″ and 8″x 8″. The standard units are of steel construction. Capacity depends on specific gravity of the material and range of size taken from each compartment. The 4″x 4″ has a capacity from 5 to 10 tons per compartment in …
Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds. Miners build walls or divert rivers to expose the diamond-bearing dry river or ocean bed.

Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining. ...
What is alluvial mining? Put simply, it's the mining of stream bed deposits (also known as alluvial deposits) for minerals. These alluvial deposits are formed when minerals are eroded...
The first stage in alluvial gold mining is to take the dredged or excavated feed material and separate the small sand faction (where the gold is found) from the larger mineral and rock fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the ...
Description. 6 inch mobile dredging unit, powered by a powerful air-cooled diesel engine, which is used for both gold or alluvial diamond bearing gravel dredging. The unit is a complete setup, fitted onto a trailer, making it easier to tow, handle and move around. With a pump capacity of 120 c/m/p/h, this pump can dredge through gravel smaller ...
Alluvial gold is a kind of gold ore produced in the bottom or low-lying areas of rivers, mixed with stone sand that can be washed out. Artificial gold panning is a common gold mining method for alluvial gold, but with the development of mineral processing technology, the alluvial gold mining method has become diversified, the type of …

A horizontal tunnel drilled through a diamond pipe is called a Drift African diamonds are recovered from pipe, alluvial, and marine deposits The shift in emphasis from alluvial to primary diamond mining was due to improved technology Most modern diamond-mining operations are large in scale and extremely expensive
• Coastal and inland alluvial mining When diamond deposits are found in coastal areas, mining companies may be required to remove soil and plant life before they begin mining. Mining of beaches and inland alluvial diamond deposits can also require the removal of overburden (such as sand and soil) and the construction of sea-walls.
Benefits of using the 4 inch wash plant. This unit is designed to work on difficult to enter areas, such as bushes and/or brush fields. It is completely portable and modular in …
factors determining the revenue of a diamond deposit. Since the diamond SFD typically varies spatially in an alluvial deposit, it should be modelled locally. A data set from an alluvial deposit was used to compute experimental simple- and cross-variograms for variables representing diamond abundance in a range of standard granulometric classes.
The proposal encompasses the mining and processing of approximately 12 million tonnes of alluvial gravels extending for a distance of 2.5km downstream beyond current mining operations in Smoke Creek. Figure 2 shows where the proposed mining would take place in relation to the existing processing facilities.
• No "proxy" for alluvial diamond grades and distribution • Alluvial diamond deposits are not characterised by the presence of any "indicator" minerals, such as heavy minerals or microdiamonds. • There are no associated geochemical signatures that may be used for determining the distribution of mineralisation in an alluvial ...
