  • The Metallurgy of Cyanide Gold Leaching An Introduction

    Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen the ore should either be sufficiently porous for cyanide to reach the gold or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed i.e. the gold is liberated.

    ) has been used to leach gold over 100 years since it was patented in 1888 by MacArthur and Forrest brothers (MacArthur et al. 1888). Despite the longterm use of cyanidation there is a growing interest in noncyanide gold technology based on the lixiviants noted in Eqs.

    CLS will leach pieces of gold 40 mesh and smaller within 8 to 12 hours. This is a definite advantage over cyanide which can take up to a week to leach 40 mesh gold. This presents a number of tradeoffs between CLS and cyanide. In most cases the CLS leaching system can be built much smaller than the cyanide system.

  • Cyanide Leaching Mining SGS

    Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process a cyanide solution or lixiviant is percolated through ore contained in vats columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.
