Gold, recognizable by its yellowish cast, is one of the oldest metals used by humans. As far back as the Neolithic period, humans have collected gold from stream beds, and the actual mining of gold can be traced as far back as 3500 , when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such .
Placer gold mining led to underground mining when it was learned in 1825 that the metal also existed in the veins of white quartz rock. The search for underground gold required much more money, labor, and machinery. Underground work at Reed was not begun until 1831.

Interested in using mercury to recover gold and silver and get all the gold out of your black sands? There is often some very small sized gold in our concentrates, and it can be a lot of work to get all the gold out. Yet we make a lot of effort to capture the gold and we don't want to throw any fine gold away as it can be so valuable.
Cyanide extraction of gold through milling of highgrade ores and heap leaching of lowgrade ores requires cycling of millions of liters of alkaline water containing high concentrations of potentially toxic sodium cyanide (NaCN), free cyanide, and metalcyanide complexes. Some milling operations result in tailings ponds of 150 ha and larger.
Nov 01, 2010 · The reaction is highly exothermic and produces chlorine, a highly dangerous gas. Chlorine gas was used as a chemical weapon during the first World War, under the name bertholite. In fact, the chlorine produced by mixing hydrochloric acid and chlorine bleach is what will dissolve the gold to form gold(III) chloride.
Two recent unplanned detonations occurred during blasting operations in sulfidebearing ores in a Nevada surface gold mine. Other premature detonations have also reportedly occurred at other Nevada, California, and Arizona operations within the past few years, with increasing frequency. Unplanned or premature detonations can be extremely hazardous to life and can cause extensive property damage.

Extraction of Metals. Industries extract metals from their ores. What are ores? Let me explain in a simple way. Usually, less reactive metals such as gold and silver are found in their pure form in the soil. But this is not the case with more reactive iron or aluminum. Usually iron and aluminum exist as compounds, with oxygen, also known as oxides.
