Mercury ore is obtained through the extraction process. Following steps are involved in the process

Step 1- In first step, ore is roasted.

2HgS + 3 o2  -----> 2HgO+ 2 SO2

Step 2- In this step, the mercury oxide is heated strongly at a 300-celsius temperature. Mercury oxide decomposes at this temperature and pure mercury metal is obtained.
