A process has been evaluated, on a continuous pilot plant scale, to treat refractory gold arsenopyrite/pyrite . concentrates. The process consisted of biological leaching to partially oxidise sulphides, followed by pressure leaching for complete sulphide oxidation and arsenic precipitation, followed by liquor neutralisation and cyanidation of ...

2006-9-1 Over the last 10–15 years, a variety of biological and chemical leaching processes have emerged for overcoming the passivation of chalcopyrite. A number of these processes are now entering commercial production or are approaching this status. The BIOCOP™ process of BHP Billiton has now been commercialized at the Alliance Copper plant in Chile.
2016-4-15 Pilot plant is a relative term in the sense that plants are typically smaller than full-scale production plants, but are built in a range of sizes. (A pilot plant is a small scale replica of the full scale final plant that is not yet built to provide design data for the ultimate large one). ¾ Model: A ...
