the treatment of sulphide ores. The most common approach is bac terialassisted heap leaching, though one major project (Escondida) is planning ammonia leaching of sulphide concentrates, which was practiced commercially by Anaconda in Montana in the '70s. In the past, the flow of innovations has tended to be into the region from the outside.
Nickel processing Extraction and refining |
In the case of sulfides, the reaction of oxygen with iron and sulfur in the ore supplies a portion of the heat required for smelting. Oxide ores, on the other hand, do not produce Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used.
Ingots and the Bronze Age Copper Trade in the Mediterranean
Copper sulphide metallurgy requires a roasting process to oxidize the sulphur before smelting can take place; the presence of massive sulphide inclusions, many containing iron, and the porosity of the casting in some ingots probably indicate the imperfect nature of the earliest roasting operations.
