Description: "This paper discusses two reagent development projects the author was involved with. The first project was the development of LIX 87QN, a reagent developed specifically for the Queensland Nickel plant. After testing most commercially available reagents, and piloting one for 6 months, it became apparent a new reagent needed to be developed and it needed to be developed in “weeks not months”. The second project was the development of XI-57. This reagent was developed for use in the Escondida ammonia leach / SX / EW plant for copper recovery from chalcocite concentrate. LIX 54, the SX reagent used in the plant, reacted with the relatively high ammonia concentration in the leach solution to give a degradation product that caused severe operating and copper quality problems. In both cases the development of the particular reagent was speeded significantly by asking one or two key questions. This presentation will discuss the respective plant processes, the key questions asked and answered and how this significantly speeded the development of LIX 87QN and XI-57 "
