A phenomenological mathematical model of the gold cyanidation process, calibrated with a set of industrial data from an Australian plant, together with an economic performance index is used to analyze this problem. The simulated results show that the best compromise between the two antagonistic effects, cyanide consumption and gold recovery, which are both function of cyanide concentrations, leads to a reagent distribution that depends on the leaching and cyanide consumption kinetics, pulp feed characteristics, and economic factors such as the gold market value. For the specific studied plant, in the operating range of low cyanide consumption and fast gold dissolution, all the cyanide must be added in the first tank; however, in the operating conditions of high cyanide consumption, cyanide has to be distributed in the first, second and third tanks.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2012-07-06T14:46:58Z No. of bitstreams: 1 CC.pdf: 420625 bytes, checksum: 0b528e5d00f8267e194f0a52d1526c5b (MD5)Made available in DSpace on 2012-07-06T14:46:58Z (GMT).
