Slag

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 the smelting, and minimizing any re-oxidation of the final liquid metal product before the molten metal is removed from the furnace and used to make solid metal.

Ore smelting

In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed. In many smelting processes, oxides are introduced to control the slag chemistry, assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case, the slag is termed synthetic. A good example is steelmaking slag: quicklime and magnesite are introduced for refractory protection, neutralising the alumina and silica separated from the metal, and assist in the removal of sulfur and phosphorus from the steel.

Slag (disambiguation)

Slag (a liquid) is a by-product of smelting ore. Slag, as a liquid, is distinguished from dross, which is a solid.

Welding slag (a solid) is a form of slag produced as a byproduct of some arc welding processes.

Slag (play)

Slag is a 1970 play by British writer David Hare.Original cast: Lynn Redgrave, Anna Massey, and Barbara Ferris. Originally staged by the Royal Court. London

Slag is a biting satire in which the only characters are the three teachers of a tiny isolated girls' school. The play begins with a mutual vow reminiscent of the vow beginning the play Lysistrata in which Greek women vow to deny men sex to protest the Peloponnesian War. The three women teachers mutually pledge to abstain from sexual intercourse, in protest against the dominance and abusive treatment of women by men, epitomized in the slur against women as "slags." Conflicts among the teachers' different visions of radical feminism, different motivations, and different interpretations of and commitment to the vow become the grist for duplicitous dominant and abusive acts among them and distracts them from their teaching. Dominance and Feminism are ridiculed alike, while the number of pupils dwindles to zero in the resulting dysfunctional environment, leaving the three teachers to go their separate ways.

Debris

Debris or débris (UK: /ˈdɛbriː/ or /ˈdeɪbriː/; US: /dᵻˈbriː/) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, discarded, or as in geology, large rock fragments left by a melting glacier etc. Depending on context, debris can refer to a number of different things. The first apparent use of the French word in English is in a 1701 description of the army of Prince Rupert upon its retreat from a battle with the army of Oliver Cromwell, in England.

Disaster

In disaster scenarios, Tornado leave behind large pieces of houses and mass destruction overall. This debris also flies around the tornado itself when it's in progress. The tornado's winds capture debris it kicks up in it's wind orbit, and spins it inside it's vortex. The tornado's wind radius is larger than the funnel itself. In fact some studies suggest that in EF-5 tornadoes, the radius of the tornado could be classified as a new EF-6 tornado. Tsunamis and hurricanes also bring large amounts of debris. Such as Hurricane Katrina in 2005 and Hurricane Sandy in 2012. Earthquakes rock cities to rubble debris. Overall natural disasters can be very difficult to recover from. But in the end, we can always pull through what Mother Nature throws at us.

Debris (play)

Debris is an in-yer-face play by Dennis Kelly. It was first produced at the Latchmere Theatre (now Theatre 503) in London in 2003, before being transferred to Battersea Arts Centre the next year.

A one-act play where a brother and sister try to make sense of their dysfunctional childhood. The pair lie about their past creating new elaborate past stories, the central narrative is of the brother, Michael, who finds a baby who he names Debris trying to keep him a secret and alive from his alcoholic father confiding only in Michelle his sister who is fascinated with their mother's death and gives several contradicting stories of how she died.

In the first scene the brother describes coming home to see his father who has committed suicide by crucifixion. Kelly has said "I was brought up a Catholic, so, like every decent Catholic, as a child I fantasised about being crucified - it must have come from there"

Kelly original had problems getting Debris produced until approaching Theatre 503 "The play had been rejected by pretty much every other theatre around but 503 saw something in the play and decided to abandon common sense and produce it. For me it was one of the most important moments in my life"
