How is milk of magnesia prepared from magnesium carbonate?

What's the process? I can't seem to find it anywhere on the net, I can only find the process of creating milk of magnesia (Mg(OH)2) from magnesium carbonate.

Answer:
MgCO3--------- Heat ( 700 degrees centigrade )---->
MgO + water ----> Mg( OH )2

tained from the processing of naturally occurring minerals such as magnesite (magnesium carbonate), magnesium chloride rich brine, and seawater.

Large mineral deposits of magnesite are located in Austria, Brazil, Canada, China, the Commonwealth of Independent States (CIS), former Czechoslovakia, Greece, Turkey, North Korea, former Yugoslavia, and the U.S.

When heated from 700°C to 1000°C, magnesium carbonate thermally decomposes to produce magnesium oxide and carbon dioxide:

MgCO3 --heat-->MgO + CO 2(gas)
