DIAGNOSTIC LEACHING IN THE DEVELOPMENT OF

1987-1-1  The diagnostic leaching results show that the majority of the locked gold is associated with the copper mineralisation. Thus with direct cyanidation sodium cyanide consumptions will be high. Further investigations were conducted to determine the feasibility of producing separate copper and arsenic concentrates for treatment by various methods.

2013-10-1  Variants of the diagnostic leaching methodology have been applied to several different ore types, in particular gold (Lorenzen and Tumilty, 1992), copper (Parkinson and Bhappu, 1995), and lateritic nickel ores (Botsis et al., 2011, Swamy et al., 2003). In our research, we have developed tests that are run in parallel rather than in series with ...

1992-3-1  Diagnostic leaching was developed at the Anglo American Research Laboratories [1,2] to answer the above questions and in doing so it opened-up the field of mineralogical analysis to the metallurgist. With diagnostic leaching, the metallurgist or scientist is able to get a much clearer view of which minerals the gold is associated with.

Effect of Ultrasound on the Oxidative Copper Leaching

The objective of this study is to compare the reaction kinetics of copper leaching from chalcopyrite in acidic ferric sulfate media with (UAL) and without (non-UAL) ultrasound assistance. Four leaching parameters were evaluated and optimized. The parameter with the strongest effect was temperature, followed by ultrasonic power, the solid-to-liquid ratio (S/L), and acid concentration.
