A fresh approach to sulfide ores
· A smelting workaround. The traditional route for extracting copper from sulfide ores is smelting. Yet there is a growing case for leaching sulfides from lower grade ore bodies and especially for those ore bodies containing problematic elements like arsenic, which make smelting less economical. Smelting is increasingly expensive because, in ...
Roasting, smelting, and converting are pyrometallurgical process steps that are based on the relative affinities of metals for sulfur and oxygen. A typical process flowsheet is shown in Fig. 1 on sulfide is primarily converted to oxide in roasting. When only about half the iron is oxidized during roasting, less nickel and copper sulfides are oxidized.
Methods of Processing Ores from the Udokan Deposit ...
· The various pyrometallurgical and hydrometallurgical methods that have been examined for processing ores from the Udokan deposit are not cost-effective. It is proposed that all oxidized and low-grade ores in the deposit be processed by heap leaching and that the high-grade, readily concentrated ores be processed by the traditional pyrometallurgical scheme.
PYROMETALLURGICAL PROCESSING OF SULFIDE …
The main task of pyrometallurgical processes is consecutive removal of iron sulfide from complex sulfide system. Oxidation of iron sulfides is accompanied with heat release, hence, the possibility of specified autogeneous pyrometallurgical process in an apparatus of certain design is revealed by solution of extended equation of heat balance

· Zinc smelting is the process of converting zinc ores into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point. There are two methods of smelting zinc: the pyrometallurgical process and the electrolysis process; both methods are still used ...

· 70% of the world''s copper resources – estimated to be worth more than $20 trillion – are tied up in primary sulfide ores. The majority of this ore is too low-grade to justify traditional processing, and the alternative low-cost method of leaching does not work well on primary sulfides, despite decades of industry efforts.
