Ground calcium carbonate used in the manufacturing of roofing, flooring, and other building materials. Ground calcium carbonate is often used to increase durability and reduce costs by displacing or "extending" other raw materials that are more expensive. It is the ideal raw material as it has low absorption qualities, consistent particle size distribution and color.

Physical and chemical and mineralogical characteristics of LD steel slag. It has been found that the density of LD slag lies between 3.3-3.6g/cm. 3 Due to its high Fe content, steel slag looks in appearance a loose collection, and appears hard and wear resistant. The grindability index of steel slag is 0.7, in contrast with the value of 0.96 and 1.0 for blast …
Nearly all crushers produce a product that is 40% finer than one-half the crusher setting. Source: Babu and Cook; The product of a jaw crusher will have a size distribution such that the -80% fraction size (d80) is slightly less than the open-side setting of the crusher. For example, if the open- side setting is 6 inches, the d80 product size ...

If the operation is stopped as soon as the metal is tough, the losses of silver in the slag are small. The losses of gold in the slag are insignificant, and bullion 990 fine in silver and gold may be obtained from metal only 500 fine in an hour or two. The slag prevents loss by projection or volatilisation, and the cost is trifling.
