Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to

Apr 10, 2019Gravity separation is one of the oldest and most common methods of gold selection. In the gold deposits, gold is usually in the form of monomeric natural gold. The particle size is generally greater than 16 tons/m3, which is much different from the density of gangue. Therefore, gravity separation is the most effective and economical method for

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 B.C. , when early Egyptians (the Sumerian culture of Mesopotamia) used mined gold to craft elaborate jewelry, religious artifacts, and utensils such as goblets.
