This also lowers vibration and specific power consumption on the

Grinding Mill - an overview | ScienceDirect Topics

The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003). Metallic iron and iron minerals are separated by magnetic separation. The phosphorus-bearing minerals occurring in steel slag are removed in the tailings of high gradient magnetic separation.

Silicon recovery from metallurgical-grade silicon refined ...

The slag agent (CaO–SiO 2 –CaCl 2) was added to MG-Si refined slag for the separation and purification of silicon. In this process, the ratio of slag to silicon was 1:1, so that a large amount of slag agent was needed. Meanwhile, the smelting process for silicon recovery

A new technological approach to the granulation of slag ...

2021-11-3 · The technological factors required to improve the operational properties of granulated metallurgical slags demanded in the building industry have been analyzed. In order to satisfy these factors, a new technology for hydro-vacuum granulation of slag melts (HVG) has been developed. It is shown that the main advantage of the proposed HVG process is the provision of forced high-speed

High efficiency grinding of blast furnace slag ...

2017-9-13 · Grinding of blast furnace slag is conventionally performed in a tube mill with a dryer, which is a power-intensive option. Energy efficiency of this process can be improved by grinding the blast furnca slag using vertical roller mills (VRM) or by using a VRM as a pre-grinding step for the tube mills. It is important to note that the iron grains ...
