2. Whatis air pollution?
-Air supplies us with oxygenwhich is essential for our bodies to live.
-There are several main typesof pollution.
The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.

2. What is the Air Pollution?
Toxic or radioactive gases that introduced into the atmosphere as a result of human activity.
Dirty air that could injure human health or property, or animal life, and/or prevent normal plant use and enjoyment of property.
Tannery effluent contains large amounts of pollutants, such as salt, lime sludge, sulfides, and acids. The process of tanning stabilizes the collagen or protein fibers in skins so that they actually stop biodegrading—otherwise, the leather would rot right in your closet. People who work in and live near tanneries suffer, too.

The Ball Mill, B-101, grinds the 0.25" ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.
