In general, higher reduction temperature produces larger metal diameter (Fig. 5d). The maximum metal diameter of 6.85mm was obtained by the addition of copper smelt-ing slag into manganese ...
Slag from copper flash smelting contains not only slag-forming components, but also copper levels comparable to that in ores from modern mines (~1 wt%). In addition, it contains iron oxide (~50 wt%), alkalis and heavy metals (K, Na, Zn, Pb++, ~3–5 wt%), as well as smaller amounts of molybdenum, cobalt and nickel.
Abstract: Copper slag is generated when copper and nickel ores are recovered from their parent ores using a pyrometallurgical process, and these ores …
The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and cobalt from copper slag was investigated through the process of sulfation roasting–water leaching and the process of sulfation roasting–sulfate …
The copper production in the Alps began three thousand years BC, usually near ore deposits in Austria and Switzerland. For copper smelting, sulphidic ores like chalcopyrite and fahlores were used.
The article is devoted to the archaeological iron slag. One of the most serious problems in russian archaeometallurgy is that iron slags have been ignored by russian archaeologists as a source of information. ... 245 Elena Silvestri, Paolo Bellintani, Andreas Hauptmann Bronze Age copper ore mining and smelting in Trentino (Italy) 261 Markus ...
A recovery ratio of 97.47% Cu in the copper phase was obtained at a lower temperature and shorter duration compared to the pyrometallurgy methods. Wang et al. [ …
With the increases in the costs of iron and copper ores, the incongruity between the significant imports of these ores into China and the ongoing accumulation of unused copper slag has greatly increased. Even so, there are few low-value methods for the utilization of copper slag. The present work demonstrates the processing of this …

The most common ore minerals that remained in the slag sample were sulfidic solid solutions of copper and iron such as Cu 5 FeS 4, Cu 2 S, and Cu 9 S 5 …
In the production of copper from sulfide ore, slag accumulates at the processing plant. In the present work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be …
The collection of mineral deposits at the Natural History Museum Basel includes different types of coal (turf, coal, asphalt, bituminous shale and oil, various salts (rock salts) and ores (iron ore, manganese ore, copper ore, molybdenum ore, nickel and cobalt ore, lead and zinc ore), as well as talc and asbestos. These minerals and rocks are ...
The main phases of the copper slag were Fe2SiO4 and Fe3O4. The suitable conditions of reduction were a temperature of 1373.15 K, a H2 partial pressure of …
Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron …
