The study of a well-preserved crucible fragment from the Middle Kingdom Egyptian fortress in Buhen lower Nubia revealed unexpected presence numerous prills very arsenic- and nickel-rich copper alloy what looks like smelting slag. Based on optical scanning electron microscopy polished section, this paper discusses potential metallurgical process that was carried out type crucible. Strongly reduc...

Abstract Novel aluminum-copper compound castings devoid of oxide layers at the interface between joining partners were developed in order to increase thermal conductivity hybrid component. Due natural both aluminum and copper, metallurgical bonds such bi-metal cannot be easily achieved conventional processes. However, an atmosphere comparable extreme high vacuum created by using silane-doped in...

Generally, trace precious metals remaining in wastewaters generated from the refining process of precious metals are not recovered, due to a relatively high processing cost as well as various technical problems. Recovery of precious metals from wastewaters is very important for the conservation of resources and the protection of environment. However, wastewaters containing a large amount of amm...

Flue dust waste coming from a copper (Cu) smelting company has been valorized using newly developed metallurgical process with the aim of recovering concentrated in valuable metals, such as lead (Pb) and zinc (Zn), studying feasibility replacing anthracite biochar reducing agent. Metallurgical trials different mixtures agents have performed furnace at 1400 °C. This employs high-power thermal pl...

Since many household systems are fabricated out of metallic materials, changes to the household environment that accelerate corrosion rates will increase the frequency of failures in these systems. Recently, it has been reported that homes constructed with imported wallboard have increased failure rates in appliances, air conditioner heat exchanger coils, and visible corrosion on electrical wir...

The process of metallurgical equipment information space is complex and diverse, including multi-level spatial information or spatial process factor. How to divide the metallurgical equipment information space, to plan its communication path intelligently and to enhance the level of intelligent equipment has become one of the metallurgical equipment systems’ problems needing to be resolved. Aim...

Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted physical, chemical, and mineralogical characterization copper slag, along with preliminary tests. article focuses flotation, which two oneyear campaigns (2016 2017). The first campaign carried out using existing circuit plant. During second (2017), for sulfide o...

Geochemical measurements on well-dated sediment cores from Lake Er (Erhai) are used to determine the timing of changes in metal concentrations over 4500 years in Yunnan, a borderland region in southwestern China noted for rich mineral deposits but with inadequately documented metallurgical history. Our findings add new insight into the impacts and environmental legacy of human exploitation of m...
