“…Distilling zinc directly from the concentrate at a temperature of 800-900 • C was attempted, with other metals left in the residue. The work on vacuum distillation of various metals was carried out by us earlier [21][22][23]. The process was performed at 0.13 kPa under vacuum for 1 h. It was found that zinc was not completely removed from zinc and brass granules.…”

The heterogeneity and local distribution of elements are established as a result of the study of nonferrous metals distribution and the composition of domestic wastes processing concentrate containing 20–40% copper, 40–50% brass, 20–28% zinc and up to 1% aluminium. Metals are mainly concentrated in granules of three types: zinc-based, copper-based and copper–zinc alloy, i.e., brass. The phase composition of these granule types and their structure are determined. Zinc granules are covered with a refractory oxide shell. A distillation processing method for such raw materials based on full state diagrams, including the phase transition of melting pairs of double systems of copper and tin with zinc and lead, is offered. The possibility of a rather complete zinc distillation (over 90%) with the accumulation of other metals in the copper-based alloy, containing more than 96 wt. % of the basic element, has been demonstrated by electric crucible melting in a highly reducing atmosphere. Copper-based alloys, after adjustment for the content of some metals (tin), can be realized as pressure-treated tin bronzes. Copper with the content of impurities corresponding to the standard for blister copper can be electrolytically processed (after dissolution in sulphuric acid) in copper production. Equipment for the implementation of the electro-thermal processing process that provides metal recycling of the metal concentrate is proposed.

“…NIST 612 standard reference material [27] was used as the external, and Si (measured with 29 Si in the MS) as the internal standard, respectively. NIST 610 as well as BHVO-2G and BCR-2G basaltic glasses were analyzed as unknowns.…”

“…Many researchers have stated that the vaporization of tellurium in copper matte smelting conditions is not significant, and tellurium cannot be removed either by slagging or vaporization due to its high stability in matte [19,20]. This conclusion does not agree with the experimental observations of Sukhomlinov et al [24] or the tellurium-sulfur phase diagram, which suggests formation of a tellurium-containing sulfide gas phase at copper matte smelting temperatures [29].…”

The modern world continuously demands more raw materials for manufacturing all kinds of products. Nowadays, the lifetime of a single product can be very short, as is the case with electronic appliances. Waste electrical and electronic equipment (WEEE) is one of the fastest growing waste categories, and one of the most promising recycling routes for WEEE is to use it as a feed material in pyrometallurgical copper smelting. This article presents new experimental observations regarding the behavior of tellurium in secondary copper smelting process, and compares the results to primary smelting experiments. In secondary smelting conditions, most of tellurium distributed into the copper phase, and the distribution coefficient between copper and slag decreased with increasing oxygen partial pressure. In the primary smelting experiments, most of tellurium was vaporized into flue dusts, and the distribution coefficient between copper matte and slag increased with increasing oxygen pressure, i.e. increasing matte grade.
