Wastes that are generated during the entire mining process i.e. extraction, beneficiation and processing are called ___________.

  1. Mining wastes

  2. Cement wastes

  3. Construction wastes

  4. Oil refinery wastes
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

During mining, extraction of minerals from rocks generates waste. In this process waste minerals are also generated. It is followed by benefaction wherein the mineral obtained is washed, crystallized etc to separate out the finer waste that comes along. After this, the mineral is chemically treated such that the waste obtained after the process is much different from the waste that entered the system.

Mercury and sulfur is the main mineral of volcanic regions of the Mediterranean sea.
Cinnabar has been found in locations worldwide, usually near the earth's surface in areas of moderate volcanic activity. It tends to be associated with hot springs, deposited by superheated water laden with elements like sulfur and mercury. 
Cinnabar is a toxic mercury sulfide mineral with a chemical composition of HgS. It is the only important ore of mercury. It has a bright red color that has caused people to use it as a pigment and carve it into jewelry and ornaments for thousands of years in many parts of the world.
