Copper and Cyanide Recovery in Cyanidation Effluents

Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the MerrillCrowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as the precipitator, and sulfuric acid for ...

Froth Flotation Method

 · (3) For refractory gold and silver ores which cannot be treated directly by mercury amalgamation or cyanidation, a combined process including flotation is needed. However, there are some limitations in flotation, such as ores with gold particles larger than mm or pure quartz gold ores without metal sulfides, which are difficult to deal with by flotation separation alone.
