The conventional treatment of copper–gold concentrates involves smelting, converting, and electro-refining to produce a copper-cathode product. The conventional treatment of copper–gold concentrates does elicit some compelling reasons to seek an alternative hydrometallurgical process for the recovery of concentrate values. These include: capital cost; impurity tolerance; lower-grade copper

Colloidal gold can be the product of exsolution of solid-solution gold or nucleation of adsorbed surface gold (Simon et al., 1999). It also forms along the ''reaction front'' where a gold-barren sulfide is replacing a sulfide or arsenide-containing solid-solution gold (Chryssoulis and Weisener, 1994; Mumin et al., 1994). Colloidal gold ranges in size between 5 and 500 nm, which is

Copper–gold carbon-loading ratios of 70:1 and eluate Cu–Au ratios of ∼6000:1 are obtained from slurries assaying ∼400 mg/L copper and ∼5 mg/L gold in solution. The carbon is continually eluted in a rubber-lined column using cold cyanide solution, before being returned to the last tank in the copper

He was born on November 19, 1939 in Cleveland, Ohio, and is a graduate of Harvard University, where he received his B.A. degree in chemistry and physics in 1961 and his Ph.D. in chemical physics in 1964.

This major symposium is in honor of the distinguished work and lifetime achievements of John H. Starkey. Mr. Starkey is a well-known figure for his strong impact on metallurgical process design including iron, base metals and gold processing. This work is especially well known in the area of autogenous and semi-autogenous grinding circuits and relating these to beneficiation. For the past 26

From 1970 to 1995, Copper, Gold, Silver, Molybdenum and a by-product Rhenium were mined, using conventional open pit truck and shovel methods. At closing more than 1 billion tons of material had been moved, leaving the deepest excavated depression below sea-level on earth. At one time, the mine employed over 900 people, and helped turn the tiny community of Port Hardy into a town of 5,000. It
