GRANULATED SMELTER SLAG**** Abstract Smelter slag is obtained in the process of metallurgical converting of copper concentrate in the Smel-ter Plant in Bor, Serbia. Today, the reserves of this material are evaluated at about more of a year, with the average copper content of 0.6-0.9%. Production of copper concentrate by flotation of smelter slag

Copper slag, an important by-product of the copper smelting process, is mainly composed of 2FeO SiO2, Fe3O4, and SiO2. Due to the sufficient metal oxides, copper slag is regard as a potential oxygen carrier (OC), which can be applied in chemical looping technology. This research proposed to use the granulated copper slag particles …

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).

The process is highly flexible; and the compact sub-plant can be applied to any furnace configuration. Granulation, dewatering and storage of the slag can be done adjacent to the furnace or can be split up to suit available plant space or logistics. Modern condensation concepts and closed loop water circuits ensure effective environmental control.
