Ladle metallurgy (LM) slag is generated during the refining process step in stainless steel making. In view of its very fine particle size, due to the transformation of β- to γ-C 2 S, and the Cr content, the slag is challenging in terms of handling and disposal and is used in only few applications. The current work explores the utilisation of the LM's fine fraction in Ordinary Portland ...

Abstract. The ultimate goal of this project is to find an efficient way to separate the slag phase from the metal phase in the molten state. A basic knowledge of the thermal, transport, and metallurgical phenomena that occur in the melting and solidification of glass, metal, and their mixtures is the foundation of the development of the separation methods.

The "slag" is the liquid metal mixture that will be the result of the temperature being raised to the high level that it is. To create the slag, you'll need to mix in the silica and the sodium borate chemicals into the furnace and on top of the gold-plated circuit.

They usually contain a quantity of valuable metals except for blast furnace slag and they are actually a secondary resource of metals. By applying mineral processing technologies, such as crushing, grinding, magnetic separation, eddy current separation, flotation and so on, leaching or roasting, it is possible to recover metals such as Fe, Cr ...

The method of metal and graphite inclusions extraction proposed here, provides mechanical or explosive grinding of solid slag to 0–10 mm in dimension, followed by gravity-magnetic and aeration separation of the formed fine slag-metal-graphite mechanical mixture.

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 ...

Blast furnace slag. Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

The complete separation of hot metal from slag is expected in the main trough of a blast furnace. However, in practice slag may take some hot metals away when it goes through the slag port. Therefore, it is important to optimize the slag‐metal separation in order to decrease the metal loss associated with the slag.
