new type of lixivant to leach base and precious
metal ores. The lixivant is a breakthrough in this
form of leaching as it is highly selective on
metals taken into solution (simpler downstream
extraction of metal), operates in an alkaline set
of conditions (no special materials of
construction), is regenerated as part of the
process (low operating costs), and is completely
biodegradable (environmentally benign reagent).

Metals from Smelter Slags by Alkali Glycine
Alkali glycine leaching technology offers a new
approach to retreatment of this slag. Glycine can
selectively extract copper, gold and other
valuable components while ignoring iron-rich
gangue minerals. Metals can be recovered from
leach solutions by conventional downstream
methods. Glycine losses are minimised by
recycling of barren liquor to the leach circuit.”
