· They noted that the production of copper from Faynan was in quantities 'unparalleled in the southeastern Mediterranean, with the possible exception of Cyprus', with up to 200,000 tons of slag left behind. They identified mining and smelting dating from the Chalcolithic period (4500 – 3100 BC) and running fairly continuously until the 4th century AD. A final phase

Most ESR furnaces today are started "cold" with dry prefused slag. Consarc can also provide a slag melting furnace with the ESR system that gives "hot" (liquid) slag start capability. This is most useful in situations where humidity and moisture are concerns, as well as in locations where sourcing of prefused slag is problematic.
Slag is Shannon ward smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). Within these general categories, slags can be further
Slags and matte in Vanyukov's process, an autogeneous method of processing sulfide concentrates of non-ferrous metals used in a specially designed furnace at the Balkhash copper-smelting plant (Kazakstan), have been characterized by scanning electron microscopy, energy dispersive spectroscopy and X-ray diffraction. The liquid matte was shown to have contained
· In this study, electric furnace copper slag was found to be composed of magnetic iron (Fe 3 O 4), fayalite (Fe 2 SiO 4), calcium magnesium oxide, and a silicate solid solution. The magnetic iron

Slag. Blast Furnace Slag, is produced as a result of the reduction of iron oxide to iron. It consists of silicates, the alumina silicate of lime, a minor percentage of ferric and managanese oxide and sulphur. Boulder Slag, is produced by Pakistan Steel by using a semi direct method in which slag formed from the Blast Furnaces is processed at a
