The main constituents of blast furnace slag are Cao, SiO 2, Al 2 O 3, and MgO. These are the minerals that are found in most of the cementitious substances. The particles are further dried and ground in a rotating ball mill to form a fine powder, known as ground granulated blast furnace slag.
This is known as "spread" and is a common problem in unstabilized driveways. Stabilizing Your Slag with Permeable Pavement. Unstabilized aggregate like slag is not ideal for the average driveway, but you can eliminate almost all of the problems that occur with slag by stabilizing it with permeable pavers.
Slags are sometimes treated by slow cooling, milling, and flotation. This approach is satisfactory when the metals in the slag are in either the sulphide or metallic form, but is not suitable for the recovery of oxidized metals. Cobalt in particular, and nickel to a lesser extent, are found in an oxidized form, and for these slags, treatment in ...

The slag is tapped at temperatures around 1350ºC, and the matte is somewhat cooler, around 1200ºC. The unwanted slag constituents are discarded (usually after being subjected to granulation using a high-flow water stream, milling, and flotation to re-capture any entrained droplets of matte).
The electron-binding energy of ball milling 2.5 h slag is the smallest and that of raw slag is the largest; thus, from the binding-energy value, it can be concluded that the aluminum in the raw slag is mainly in the state of six-coordination, and the aluminum in the ball-milled CGS is mainly in the form of the aluminum–oxygen tetrahedron ...

Air is circulated in the mills for homogeneous grinding. The product obtained after grinding is Portland slag cement. Another known process (L. Opoczky, Grinding technical questions of producing composite cements, Int. J. Miner. Process 1994, 44-45) uses grinding of cement clinker and granulated blast furnace slag separately in a mill.
Thus, slag from bin 2 is milled in Cascade mill 3 in a semi-autogenous manner (the mill contains only about 0.5% to 2.0% charge of steel balls) to produce pulp 80% of which passes 100 mesh. This pulp is conveyed via screw classifier 4 and pump 5 …
