Leaving pillars of standing rock or timber braces are some of the techniques used to hold up the rock roof as mining progresses. Placer. Placer diamond mining, also called alluvial mining, involves sifting through sand and gravels to extract diamonds. This method is common in Africa and used by most of the local people for diamond mining.
The tropical alluvial deposits (placers) are saturated with water. Floating dredges are used to mine alluvial deposits. This type of exploitation is the least expensive method of mining. The operational cost is 0.1 to 0.2 mg/m3. Only few paleochannels are more than 50 feet (15 m.) deep.

Alluvial Gold Mining. 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.
Alluvial Prospecting and Mining (Second Revised Edition) focuses on the emergence of improved mining techniques and methods used in the excavation of alluvial deposits. The book first offers information on the prospecting methods, sampling, and valuation.
In the case of artisanal mining, the extraction process usually takes a longer time as it involves low tech equipment and manual labor. Compared to alluvial mining, the post-processing is shorter and is a less resource-consuming task as diamonds are identified in situ of the work area. Offshore Marine Diamond Mining

With a few notable exceptions, alluvial diamond mining is the preserve of the individual digger and the small-scale, if more technically sophisticated miner/ digger -- a private, rather than a corporate operation. Corporate interest in alluvial diamond mining began in New South Wales in the late 19th century and in Namibia a few decades later.

The i350 is a family member of the Falcon Gravity Concentrators Gold Mining Equipment which has revolutionizing the world of alluvial gold mining and dredging the same way its little brother, the i150, has impacted the world of hard rock mining.. This is a gravimetric mineral concentrator that uses enhanced gravity (G's) to concentrate the 'free' heavy minerals.
Hydraul ic mining techniques were used ... using tunnelling equipment. Placer mining is fr equently ... Generally used most often for mineral-sands and some near-shore alluvial diamond mining.
The first diamonds discovered in South Africa were from alluvial deposits. Today, industrial alluvial mining involves building a large wall to collect the water in one area. Diamonds are often found in the gravel layer, which collects under layers of other material, such as mud, clay and underwater plant-life.
As it is my opinion that deep alluvial mining methods in Victoria and in the Murray Flats in New South Wales are practically in their infancy, and considering that we, the old school, of alluvial miners, who have thirty or forty years' experience to guide us, must in the natural order of things hand over the management of our mines to the younger and less experienced generation of miners, I ...
Gold Mining Process And Techniques For Mining Gold. Modern gold mining processes are largely the same techniques used in gold mining for hundreds, if not thousands, of years.

Placer mining is the mining of alluvial sediments for minerals. This may be through by open-pit (also known as open-cast mining) or by a variety of forms of tunneling into antique riverbeds. Excavation might be achieved using water pressure (hydraulic mining), layer digging out equipment or tunneling equipment.
