Metallurgy in pre-Columbian America is the extraction, purification and alloying of metals and metal crafting by Indigenous peoples of the Americas prior to European contact in the late 15th century. Indigenous Americans have been using native metals from ancient times, with recent finds of gold artifacts in the Andean region dated to 2155–1936 BCE, and North American copper …

Slags with lower copper content (e.g., smelter slag) may be processed by mineral dressing techniques or in slag cleaning furnaces to increase the amount of copper recovered. In a slag cleaning furnace, the copper in the slag is removed and recycled back to the process. The resulting slag is referred to as cleaned slag.

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...

Some properties of a typical copper slag are shown in Table I, and it can be observed that air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from 2.8 to 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the

The experimental work was performed under slag-cleaning conditions for different levels of Fe in the matte and for a range of Fe/SiO ratios in the slag. All experiments were carried out under conditions where three phases were present (copper-matte-slag), which is the condition typically prevailing in many slag-cleaning electric furnaces.

This paper deals with the experiments conducted to study the effect of copper slag, GGBFS (Ground Granulated Blast Furnace Slag), metakaolin on the properties of concrete. While GGBFS and metakaolin are used as partial substitutes for cement, copper slag is used as a partial substitute for fine aggregate. This study investigates the mechanical strength of the concrete in terms of compressive ...

Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.
