flotation gold ore

  • Rcovery of gold in pyritic ores

    Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.

  • Gold flotation,Gold processing,Gold ore processing

    Characteristics of native gold flotation Native gold is a mineral that is easy to float,the crystal structure of native gold is metallic lattice,forming the character of the metal bond. Because of the weak metal bonding force, the native gold has the characteristics of small surface wettability and easy to float.

  • Gold Extraction and Recovery Processes

    The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
