Carbothermal reduction of copper smelter slag for recycling into …
Increased demand of copper in the last few decades resulted in the generation of a large amount of smelter slag. About 80% of the world's copper to date was produced from sulfide ores by concentrating followed by the pyrometallurgical operations such as smelting and refining (Heimlich et al., 2010, Fan et al., 2014).While slag from blast furnace in iron making has found …

Zinc and Lead Metallurgical Slags as a Potential Source of Metal
1. Introduction. Metallurgical slags resulting from zinc and lead production processes are characterised by a diversity of technical parameters, chemical and mineral composition, which in turn depend on the type of feedstock used, i.e., zinc–lead concentrates (type of bed), additives used in the processing (e.g., fluxes), the technological process applied and its course.

Copper slag as a potential source of critical elements
The granulated slag is processed in the slag milling plant and the by-product sulphuric acid is sold to industrial consumers in Namibia (Dundee Precious Metals, 2020). Tsumeb blister copper production benefits distinctly from the considerable tolerance of the Tsumeb smelter towards arsenic and lead in copper concentrates feed (Mapani et al., 2014).

Utilization of granulated lead slag as a structural material in roads
AbstractPyrometallurgical processing of lead ores generates large amounts of slag which is stockpiled as chunk or granules. Romanian dump heaps of such slag produced in the period 1972–1998, occupy an area of 4522 m2 and a volume of 6616 m3. To assess the possibility of using this material in road construction, a complex characterisation of this waste …
