#0183;#32;Although dredge mining has been used for centuries, there are some environmental concerns related to the technique. For example, there are concerns that it may alter a rivers shape and muddy its waters by unsettling the addition, some researchers claim that dredge mining may release mercury into the river when the sediment is disturbed.

Where to Find Gold in a River . Assuming you have a basic Gold Prospecting Kit, the next thing you need is knowledge. Knowing where to find gold in a river will save you a lot of time, a lot of work and also increase your prospecting efficiency. On this page i will give you the general rundown of where gold will accumulate in a river system.
While some goldbearing creeks and rivers tend to have gold values dispersed throughout their entire streambeds, there is generally not enough gold to make a smallscale mining operation payoff very well. Because we are limited as to how much gravel we can process as smallscale miners, we need to find highergrade deposits.
Panning gold is basically simple, once you realize that you are doing the same thing that the river does when it causes gold to concentrate and deposit during flood storms.. The process basically consists of placing the material that you want to process into your pan and shaking it in a left to right motion underwater to cause the gold, which is heavy, to work its way down toward the bottom of

Finding Gold in a River Gold: Where is it in the River? Excerpted from Let''s get Physical, by James C. McNeill (copyright 1995) Gold is found in lode deposits, residual deposits, alluvial
Gold processing Gold processing Refining: Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more
The Mining Process. The Mining Process. this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70 water is pumped to the water treatment plant and treated to the required standards before discharge into the Ohinemuri River. 9.
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
HOW TO STRIKE GOLD. The first step is finding the right spot in the river where the gold might collect, such as a crook in the bedrock, idle pools, log jams, inside corners of rivers or spaces
Gold miners too take special care to make the impact of mining for gold as light as possible. Reclaiming land to its previous natural state is the final and perhaps most important step to ensuring the process of obtaining gold doesnt result in permanent damage to the landscape.
Most of the gold mined in California and in rivers across the United States during the height of the gold rush was placer gold. During the 1840s through 1860s gold mining in the United States focused on rivers where miners recovered lose gold nuggets from river beds using simple mining tools such as
