Hard Rock Gold Mining Equipment Definition and Significance of Hard Rock Gold Mining. Hard rock gold mining is a method that involves extracting gold from underground deposits of solid rock, rather than from alluvial deposits (sediments in rivers, streams, or other water bodies). This type of mining requires specialized hard rock gold mining equipment and …

Gold is a precious, conductive, and pliable metal that retains a stable value better than many commodities. Its chemical properties make it useful for the manufacture of computers parts and electronics. Some people find it profitable to attempt to extract the gold from these scraps, then refine and sell it.

In other words, only 2% of the amperage is depositing gold and 98% is doing something else. It would take 50 times more amperage to deposit a gram of gold from a 2% efficient solution than it would from a efficient solution. At a seawater concentration of .0088mg/m3, that would be .0000000088g/l.

More than ten million small-scale miners (SSM) worldwide use mercury to extract gold, releasing large amounts of the toxic element into the environment. Alternatives to mercury have been suggested over the years to little avail. A group of miners in the Philippines has demonstrated that borax, when used as a flux for smelting gold out of heavy

Yes, it is possible to extract gold from seawater in theory, but it's really not practical to do so. It is estimated that there is, in total, about eight million tons of gold dissolved in the world's oceans. While this is a lot, the oceans are huge, and the actual concentration of gold in seawater is only about 0.0000000006%.
