The answer is Cinnabar.

Explanation:

The ore of mercury is cinnabar. Its formula is HgS and is called mercury(ii) sulfide.

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.

2HgO+ heat ------> 2Hg + o2
