processing slag from ferroalloy production

  • 12.4 Ferroalloy Production - US EPA

    12.4 Ferroalloy Production 12.4.1 General Ferroalloy is an alloy of iron with some element other than carbon. Ferroalloy is used to physically introduce or "carry" that element into molten metal, usually during steel manufacture. In practice, the term ferroalloy is used to include any alloys that introduce reactive elements or alloy

    Oct 08, 2019· However, the physico-chemical properties of the ferroalloy are very important since it has a major effect on the recovery of the ferroalloy. The recovery rate of the ferroalloy or simply the recovery of the ferroalloy is the amount of the element which actually increases in the liquid steel composition rather than being lost to the slag.

    Jan 06, 2005· Most ferroalloy plants lose considerable amounts of metal in their slag and metal–slag mix. A potential source of income for alloy smelters is the massive reserves of metal contained in their slag dumps. Depending on the smelting process and the age of the slag dump, the metal contents vary between 3% and 15%.
