"Alkali" and "Magnesium" to improve pellet performance ...

This is because the magnesite also increases the porosity of the pellets during the preheating and roasting of the pellets, and MgO can increase the melting point of the slag phase and the floating body, so that it is not easy to melt during the reduction process, and the pores of the pellets are not melted. The material is filled to maintain a high porosity, which is conducive to

Magnesium: extraction-Metalpedia

Step 1: Dolomite ore is crushed and heated in a kiln to produce a mixture of magnesium and calcium oxides, a process known as calcining: Step 2: The next step is reduction of the magnesium oxide. The reducing agent is ferrosilicon (an alloy of iron and silicon) which is made by heating sand with coke and scraps iron, and typically contains about 80% silicon.

Magnesium: current and alternative production routes

Magnesium’s use in both aluminium and steel production strongly links its demand to these two other metal commodities. The usage of magnesium has historically been limited by relatively high cost of production and associated energy costs. There have also been scientific issues around alloy development, in particular, increasing creep resistance for drive train applications
