INFLUENCE OF LEAD NITRATE ON CYANIDE LEACHING OF increase in gold and silver recoveries between 0.41.2% for gold and 3.911.6% for silver at the end of 24 hours leaching by the addition of lead nitrate as 0.10.5 kg/Mg. NaCN consumption decreased or did not change except for the Ovacik ore. In the case of the Ovacik ore it slightly increased. Keywords: lead nitrate, gold, silver, cyanide Effect of L

Copper, Silver and G

Silver and g were traditionally weighed in troy measure. A troy pound contained 12 troy ounces or 240 pennyweights (pwt), and was 373.2417 g. The prices of silver and g are quoted in dollars per troy ounce for 0.900 fine metal. On 22 November 2002, the New York spot price of silver was 4.475, and g 317.65. Sterling silver is 92.5 Ag

G and Silver Leaching by Cyanidation

Introduction to G and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting g from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.
