BIOX® Process OutotecThe process was developed for the pretreatment of refractory concentrates ahead of conventional cyanide leaching for gold recovery. As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide.
Copper Smelting IFCsitu leaching of copper ores; from an environmental point of view, this is a questionable production route. Several different processes can be used for copper production. The traditional process is based on roasting, smelting in reverbatory furnaces (or electric furnaces for more complex ores), producing matte (copperiron sulfide), and con
Bioleaching WikipediaBioleaching is the extraction of metals from their ores through the use of living is much cleaner than the traditional heap leaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.
COPPER(II) EXTRACTION FROM AMMONIA LEACH SOLUTIONAbstract: Hydrometallurgical processing of copperbearing materials (ores, concentrates, byproducts) is usually done with the use of acidic or ammonia leaching. In the case where a leaching feed material contains significant amounts of carbonate rocks and iron minerals the second method is preferential due to a higher process selectivity.
