    Jan 01, 2016 Zn leach residues. 1. Introduction. Although most of the gold produced each year originates from primary gold ores or concentrates, a significant amount of gold is recovered as byproduct from the production of base metals (BMs) and from the recycling of scrap. From a gold world production of approximately 2600 metric tons in 2004, about 10% was
