Precious Metal Heap Leach Design and Practice

 

Precious Metal Heap Leach Design and Practice Daniel W Kappes1 ABSTRACT Heap leaching of gold and silver ores is conducted at approximately 120 mines worldwide Heap leaching is one of several alternative process methods for treating precious metal ores and is selected primarily to take advantage of its low capital cost relative to other methods Thirty seven different heap leach

Reduction of Thiourea Consumption in Gold Extraction by

  The thiourea leaching of gold and silver from the gold bearing silicate ore of the Hishikari mine Kagoshima Japan was studied The apparent activation energy of the extraction of gold and silver was smaller than that of the reaction rate of thiourea consumption by ferric iron We carried out the leaching after the leaching solution was preserved for several hours The gold recovery at 288 K

In Malaysia the amount of electronic waste e waste generated in 2008 was stated to be around 688 000 metric tonnes and was forecasted to increase to million metric tonnes in the year 2020 1 Typical e waste contains some elements of precious metal which is mainly generated from the result of the revolution of computer technology.

Effect of Acid Leaching Pre Treatment on Gold Extraction

  Low gold dissolutions are due to the high content of copper around 30 in PCBs which has a strong negative effect on the kinetics of the gold leaching reaction because copper competes with gold for thiourea with the formation of Cu CS NH 2 2 2 2 that prevails over the formation of Au CS NH 2 2 2 This occurrence is less pronounced when gold is recovered from primary raw materials
