The smelter separates precious metals in a copper bullion, from mostly all other metals, concentrated in a lead slag, further treated at the Base Metals Operations. After leaching out the copper in the leaching and electrowinning plant, the precious metals are collected in a residue that is further refined at the precious metals refinery.
Metals that during their path through the recycling chain are dissipated – for example, into dust fractions – or that are diverted by unintended co-separation into the wrong end-processes, such as precious metals directed into steel plants or aluminium smelters, are lost (Meskers et al. 2009a, b).The total efficiency of a recycling chain is …

Slag is also called molten slag. The melt that floats on the surface of liquid substances such as metals during the pyrometallurgical process is composed mainly of oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), and often contains sulfides and a small amount of metal. Slag Introduction The composition of the …

KEY WORDS: recycling; nickel slag; aluminum dross; iron-exaction; secondary slag stabilization. base and precious metals, and in the past years, extensive researches have been carried out.12–16) Although most of the works are focused on the copper and other waste slags, the thermal reduction techniques they used can still provide lots of ...
The distributions of precious metals (Ag, Au, Pd, Pt, and Rh) between copper matte and silica-saturated iron silicate slag were determined at 1523 K to 1623 K (1250 °C to 1350 °C), in controlled CO-CO2-SO2-Ar gas mixtures. The experiments were done in silica crucibles and a fixed partial pressure of sulfur dioxide for matte grades of 55, 65, and 75 …

Lead recycling has many benefits. For example, it provides an alternative to lead, thereby avoiding the environmental impacts of primary lead smelting. In addition, as with other secondary metal operations, it consumes less energy at a lower cost than primary production. An emerging process has been evaluated in which these attributes are …
Economic Impacts and Aspects of Precious Metal Recycling. Mining PGMs is expensive, costing companies millions of dollars to maintain mines, transport material, and transform mined materials into useable form. Extracting PGMs from spent auto catalysts, however, is 10 times less expensive than mining because it requires less human workforce and ...
