gold the mineral native gold information and picturesgold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. a gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver. the color of pure gold is bright golden yellow, but the greater the silver content, the whiter its color is.

silver processing britannicaa process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. this is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.

how gold is made history, used, parts, procedure each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. mining 1 in lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks. gold is obtained from lode deposits by drilling, blasting, or

gold extraction / mining gold.infoextraction of gold by the amalgam process. the amalgam process is the oldest technical method of extracting gold and was used in antiquity. with the amalgam process the gold bearing rock is likewise crushed to fine sand. afterwards mercury is added to the rock dust. gold has the property that enables it to join to the surface of the mercury.
