The Metallurgy of Cyanide Gold Leaching

Oct 20, 2014Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 m of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Specimen gold is generally found and retrieved from lode gold deposits. These are usually high-grade occurences found in quartz veins, or less commonly calcite. Gold may also be found as specimens in, or with iron oxides, adularia (a low-temperature feldspar), sulfides, and with other silica-rich minerals such as tourmaline, amythest, or clay minerals.

Setting Up the Proper Recovery System

It is reasonably safe to say that any recovery system is efficient down to a certain size-fraction of gold or platinum in any given area. The size-fraction might vary from one place to another. The reason for this is that the specific gravity of gold and platinum is generally 5 to 6 times greater than the average of other materials which commonly exist within a streambed.
