Rock wool, a man-made material consisting of natural minerals like basalt or diabase. Slag wool, a man-made material from blast furnace slag (the waste matter that forms on the surface of molten metal). Mineral wool contains an average of 75% post-industrial recycled content.
Welcome. The Ohio Aggregates & Industrial Minerals Association is the trade association in Ohio that represents all of the state's mining operations, except coal. These commodities include mostly construction materials, both natural and man-made, such as aggregates (which are sand, gravel, slag, and crushed limestone, dolomite, and sandstone), salt, clay, shale, gypsum, industrial …
Some smelter slags represent a significant environmental hazard. Since the beginning of the industrial age, slag, the glassy material left over when metals are refined from ore, has been ...
INDUSTRIAL SLAG. Industrial slag is a by-product of the copper smelting process. When in a molten state, the slag is quenched rapidly and washed by highly pressurized water. It is then granulated to create a black irregular shaped material that has a glossy appearance. Industrial slag has a very consistent chemistry and sizing.
Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace. Molt
If you have a rock that does attract a magnet, then it is also probably not a meteorite because the mineral magnetite is common in Earth rocks. Cut or break the rock open. If it has metal flecks or veins like in these ordinary chondrites, then it might be a meteorite, but more likely it is just industrial slag, which often contain metal blebs.
Slag from industrial processes is often confused for meteorites, although slag has a porous surface. Other commonly mistaken types of rock include lava rocks and black limestone rocks. If you're having trouble discerning between holes and regmaglypts, it may be useful to view side-by-side comparisons of these features online to learn how to ...
Today's rock and slag wool insulations are high-tech versions of their predecessors, produced from plentiful basalt and industrial slag. Rock and Slag Wool Composition and Manufacturing Process. Rock wool and slag wool insulations are composed of basically the same raw materials in different proportions and are produced in the same way.

The industrial slag available on the site are made of sturdy quality stainless steel that prevents all forms of rusting and possesses a multifunctional dehydrating system applicable to many industries. These powerful industrial slag are accessible with distinct capacities and the drying system can be fully customized according to your requirements.
Steel slag is a calcium-rich industrial waste. Direct aqueous carbonation is one of the routes to slag carbonation. The reaction mechanism of direct aqueous carbonation of steel slag is first discussed. Various models have been proposed to model aqueous carbonation of steel slag. The merits and shortcomings of these models are discussed.
Use of Slag. Slag plays an important role in industrial production, especially in some large factories, slag is extracted and processed into slag cement, slag fine powder, slag powder, slag Portland cement and slag cotton. Blast furnace slag can also be used as raw materials for cast stone, glass-ceramic, fertilizer, enamel, ceramics and so on.
Mary McMahon Aluminum is a common component of slag, along with silicon and magnesium. Slag is a byproduct of metal smelting, and hundreds of tons of it are produced every year all over the world in the process of refining metals and making alloys.Like other industrial byproducts, slag actually has many uses, and rarely goes to waste.

The industrial slag is rather way different, and is mainly built of silicates; industrial slags may be porous/vesicular, while the natural ones are rather not of this texture. Hard to say what kind of rock is in the image, but I'd vote for a highly recrystallized industrial slag rich in a clinopyroxene (diopside?).
Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
slag, botrom ash, boiler slag, steel slag, and rubber tire have ... Enormous quantities of domestic, industrial, and mining waste are generated annually in the United States. There are three techniques for disposal of these waste materials: (a) recycling,

On January 16, 1918, an organizational meeting of slag processors was scheduled at 3:30 pm at the Chittenden Hotel, Columbus Ohio. A total of 13 slag processing companies were represented at this meeting in addition to press and trade journal representatives from Rock Products and Building Materials, Pit and Quarry, and staff from the Ohio State Journal.
Blue slag is popular because of its aesthetic beauty and because it is a very unique and relatively rare type of rock. The type of iron smelting that produced blue slag was phased out in the late 19th century, so little to no blue slag is being created these days.

Slag usually refers to a glassy by-product of smelting ores to retrieve the metal. I use the term here to also include any man-made, rock-like by-product of heating things to high temperature. Thus, clinkers are a form of slag. Slags catch people attention because of their morphology. Many slags contain metal from inefficient separation of ...
This industrial directory contains a broad range of Slag companies serving all industries. This premier and trusted vertical directory contains manufacturers, distributors and service companies giving access to all their information available on the internet.
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 ...
Because slag is formed by the cooling of melted industrial byproducts, it often displays melt texture, such as flow marks and vesicles (holes or "bubbles" in the surface where trapped gas has escaped during cooling) and can be heavy and magnetic. It may even appear similar to some meteorites, so be wary of this meteorite impostor!
Blast Furnace Slag is the co-product of iron making in a blast furnace, while Steel Slag is a co-product of steel making in a BOF (Basic Oxygen Furnace) or EAF (Electric Arc Furnace). Blast furnace slag is used in a variety of applications including structural concrete, mineral wool, and glass manufacture. Steel slag also has numerous ...
