3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.

Subsidence happens when the weight of the land above the limestone is too much for the limestone to support. If the limestone cave collapses, it can cause damage to buildings and homes. The collapse can also be dangerous to people. Karst is a geological formation that occurs in some areas where there is a lot of limestone.

The organisms that directly cause acid mine drainage are able to thrive in water with a pH that's near zero. It's possible for a negative pH to occur if water evaporates from acidic pools, which will increase hydrogen ion concentration. Nearly 50% of coal mine discharges come with a pH that's below 5.0. Acidic water is highly corrosive ...

Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.
