Magnesium Production by the Pidgeon Process Involving Dolomite .
Mar 6, 2008 . Thermochemical equilibrium calculations indicate the possibility of considerable fuel savings and CO2 emission avoidance in the three steps of the Pidgeon process: (a) calcination of dolomite; (b) production of ferrosilicon from quartz sand, coal, and iron oxide; (c) silicothermic reduction of calcined.
Dolomite - Wikipedia
Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium. It is an important petroleum reservoir rock, and serves as the host rock for large strata-bound Mississippi Valley-Type (MVT) ore deposits of base metals.

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,.
Magnesium: current and alternative production . - Research Online
The source of magnesium can be from sea water, brine, dolomite, magnesite, and carnallite. The other process involves reduction of magnesium ores by a reactant. A list of selected magnesium production routes are given in Table 1. Electrolytic Processes. Electrolytic processes have dominated production magnesium from.
Raw Materials : Dolomite | KELSEN Refractarios | Calcinor Group
Our dolomites are very close to these values because they do not have the undesirable impurities for brick manufacture such as melting oxides SiO2, Al2O3 y Fe2O3. Mastering and controlling all the steps involved in sourcing and manufacturing this basic raw material is a critical and integral part of this process at KELSEN.
How Is Magnesium Metal Produced? - The Balance
Sep 20, 2017 . Electrochemical processes are used to extract the metal from dolomite and magnesite ore. When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride.
