During testing of the alluvial deposits, there is a tendency to bypass areas containing many large stones and easily test the finer material gathered around the boulders. In many cases, this is essentially salting the sample from which the valuable material in an alluvial deposit normally occurs in the finer material.
4: To build the alluvial gold ore beneficiation plant, miners should consider the factors like scale, management, etc. For those large-scale mines, the processing work can be a little complex. For those small-size or medium-size mines, miners should workout measures in line with local conditions, make the best use of the advantages and bypass ...
This can be accomplished by using a tube and auger testing device. Barring the availability of this type of equipment, test holes may be dug with a backhoe, dragline, or, if the soil conditions permit, a front end loader. A test pit can also be hand dug. The hand dug pit requires an appropriately reinforced test hole.
1.1.6 Beneficiation Although metallic ores contain elevated levels of metals, they generate large quantities of waste. For example, the copper content of a good grade copper ore may be only one quarter of one percent. The gold content of a good grade gold ore may be only a few one-hundredths of a percent. Therefore, the next step in mining is
Crushing and Screening. Many alluvial gold ores contain cementing mud pie and most of its particle size is over 100 mm, which will be excluded together with waste rock in the process of screening if not being crushed, thus is a loss of gold Vibrating screen and trommel are the commonly used screening equipment, which has long service life and high processing capacity.
