achieved by hand panning, and more rarely amalgamation Grinding samples to final size has produced a finer GRG distribution than that of the ore, which will increase panning losses, especially if very low yields and high grades are targetedFigure 2 shows how yield affects gold recovery (100% = gold in the ore): the effect is very
Amalgamation is a concentrating process in which metallic gold or silver, or an alloy of the two, is mixed with mercury, either in a amalgamation drum, or on a amalgamation table, where the precious metal bonds with the mercury to form the metal laden mercury AMALGAM and the waste (barren) ore pulp are caused to travel different paths to effect .
AMALGAMATION - IN METALLURGY Amalgamation is the process of extracting gold and silver from their ores by means of mercury It depends on the fact that mer cury, or quicksilver as it is usually called by metallurgists, "wets" and adheres to metallic gold and silver and penetrates them, form ing pasty amalgams of a silvery colour

he gold ores found above the waterline in the Lachlan Fold Belt of south eastern Australia in the 1850s, were free milling, meaning that most of the gold could be easily separated from the quartz by crushing, followed by amalgamation with mercury 1 The particles of gold were relatively large and separated cleanly from the quartz
amalgamation (often involving the use of mercury) Wastes from these processes include waste rock dumps, tailings, heap leach materials (for gold and silver operations), and dump leach materials (for copper leach operations) Leaching involving the use of cyanide is a kind of beneficiation process, usually used with gold.
Gold bearing ores containing liberated/free gold particles, such as alluvial/free milling ores, gravity concentrates or gravity plant tailings was found to be suitable for the CGA process, as associations with other minerals/metals, such as pyrites, arsenopyrite etc reduce the oleophilicity of gold, and hence limits gold recoveries2,3,6 High gold
