The theoretical equation for predicting volume expansion of steel slag is deduced based on both chemical reaction and physical changes of free lime in steel slag during the hydration process. Laboratory volume expansion testing is conducted to compare the results with the theoretical volume expansion. It is proved that they correlated well. It is furthermore experimentally proved that certain v...

Issue: Processed recycled glass has been sold as an abrasive blasting medium under several brand names in different parts of the United States. However, limited public information is available regarding the performance of finely sized crushed glass in abrasive applications because manufacturers have developed their own proprietary data. Historically, the predominant material used for abrasive b...

The removal of copper dissolved in liquid stags by pyrometalIurgical means such as gaseous reduction and sulfidization is thermodynamically investigated. The lowest level possible for copper content is theoretically determined and compared. The results show that gaseous reduction is not as effective as sulfidization. Slags with very low levels of dissolved copper can be obtained with sulfide tr...

An investigation was carried out in an aluminium recovery works after the simultaneous occurrence of haemolytic anaemia in two workers in the slag disposal plant. The first worker was admitted to hospital suffering from nausea, backache, and haematuria. Jaundice developed on the next day. His urine contained protein, urobilin, haemoglobin, and methaemoglobin but no red cells. During the course ...

In recent years, the demand for copper and nickel has risen world-wide due to their use in printed circuit boards, batteries, application in marine alloys (due to excellent resistance to corrosion by seawater), and a wide range applications in day-to-day life (Doebrich, 2009). Increasing demand for these metals is leading to rapid depletion of high-grade resources. Alternative sources, such as ...

After the beginning of metal processing at the transition from the Neolithic to the Bronze Age, further knowledge of ore mining and smelting had spread from the Near East to central Europe. In the copper ore deposits of Schwaz, in the central part of the Alps, the oldest traces of copper mining derive from the early to middle Bronze Ages. Investigation of a middle to late Bronze Age (1410–920 c...

The archaeometallurgy of copper have been pioneer technologies in ancient Iran and goes back to about ten thousand years ago in Iranian Plateau [1, 2]. The Haft Tappeh Middle Elamite Site is located in Southwest Iran and have been an important city belonging to early phase of Middle Elamite period (14th century BCE) [3, 4]. Based on various metallurgical evidences found in archaeological excava...
