  • Cyanidation of Refractory Gold Ores: A Review (PDF Download

    These types ofgoldmineralisation are referred to as refractory gold ores(Turney et al , 1989) Depletion of amenable ores alert researchers to decipher the polylemma associated with treating refractory ores The degree of refractoriness has been classified based on the proportion of gold recovered (Table 1) Cyanidation

  • Gold Flotation - 911 Metallurgist

    Mar 17, 2017 In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation Research leading to the development of new reagents and to our understanding of the mechanism involved has been largely in the hands of academic institutions and

  • A conceptual model for gold flotation - ScienceDirect

    A review of the literature suggests that there have been numerous studies on the flotation of free gold particles and refractory sulphides, but these investigations have typically focused on the individual flotation behaviour of each gold bearing species in synthetic mixtures and not when they are present together in real ores

  • Assessment of options for economic processing of preg-robbing

    Abstract One of the challenges facing the gold industry in the twenty-first century is the continuing need to identify new reserves of economically treatable ores Discoveries of large Ores which contain naturally occurring carbonaceous material ('preg-robbing ores') is an example of one such ore type Newmont's Jundee
