Slag - Wikipedia
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 ...

Chemical characteristics of iron and steel slag : …
Chemical composition of iron and steel slag The primary components of iron and steel slag are limestone (CaO) and silica (SiO 2 ). Other components of blast furnace slag include alumina (Alsub>2 O 3 ) and magnesium oxide (MgO), as well as a small amount of sulfur (S), while steelmaking slag contains iron oxide (FeO) and magnesium oxide (MgO).
Steel Slag - an overview | ScienceDirect Topics
Air-cooled steel slag may consist of big lumps and some powder. The mineral composition of cooled steel slag varies and is related to the forming process and stone composition. Air-cooled steel slag is composed of 2CaO · SiO 2, 3CaO · SiO 2 and mixed crystals of MgO, FeO, and MnO (ie, MgO · MnO · FeO), which can be expressed as RO phase.
Metal leaf - Wikipedia
A metal leaf, also called composition leaf or schlagmetal, is a thin foil used for decoration. Metal leaves can come in many different shades. Some metal leaves may look like gold leaf but do not contain any real gold. This type of metal leaf is often referred to as imitation leaf.. Metal leaves are usually made of gold (including many alloys), silver, copper, aluminium, brass (sometimes ...
PHYSICOCHEMICAL CHARACTERIZATION OF COPPER SLAG AND ...
in slag composition during oxidation at high temperatures [4, 5]. In case of use of basic slag, in processes such as the Mitsubishi smelter, the liquid region is extended to the right side of the diagram, given the possibility to operate at higher oxygen pressures than using silica. This fact is shown in Figure 3 where both situations
THE ESTIMATION OF SLAG PROPERTIES
and the slag composition shows a steady increase in CaO concentration and a decrease in Al2O3. Slag/container reactions Some slags are so aggressive and reactive towards the refractory walls that a process has had to be abandoned because no suitable refractory could be identified.
Chemical, Mineralogical, and Morphological …
The oxide composition of both the BOF slag and EAF(L) samples was determined by the slag processing companies (Multiserv and Edward C. Levy Co.) using X-ray fluorescence (XRF) analysis. In order to determine the mineralogical phases present in the steel slag samples, X-ray diffraction analyses were carried out on both BOF slag and on EAF(L) slag samples with a Siemens D-500 diffractometer ...
SLAG ANALYSIS SOLUTIONS - Bruker
Slag formers are either charged with the scrap or blown into the furnace. The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 (fluxing oxides). As oxygen is blown into the furnace, the principal flux (FeO) is generated. The "slag balance" now starts to shift and the slag becomes more liquid.

The borax contribution to flux composition can be up to 60% of total flux weight but is typically around 30-40%. Borates are also used to facilitate the attack of gold ore at a lower temperature and to make the slag more fluid at the furnace operating temperature, thus reducing viscosity. The benefits of Dehybor in gold refining are numerous:

Iron and Steel Slag Statistics and Information
Slags are nonmetallic byproducts of many metallurgical operations and consist primarily of calcium, magnesium, and aluminum silicates in various combinations. Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the
