Experiment 1: The Effects of Coal Mining Coal mining‚ particularly surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp. Activated

Chemistry Assessment Coal is a combustible rock of organic origin composed mainly of carbon (50-98%)‚ hydrogen (3-13%) and oxygen with lesser amounts of nitrogen‚ sulphur and other elements. Some water is always present‚ as are grains of inorganic matter that form an incombustible residue known as ash. In New South Wales‚ black coal is mined near the eastern and western edges of the Sydney-Gunnedah Basin where the seams are relatively close to the surface. Mining along the western edge‚ where

Introduction The earliest traces of mining can be traced back to our prehistoric ancestors with the oldest mine on record being the Lion Cave mine in Swaziland‚ with radiocarbon dating it to be 43‚000 years old (Weisgerber‚ G.‚ & Pernicka‚ E. 1995). There is even speculation among scientist that the mining of Lion Cave could probably date back even further to 70-110‚000 years (Weisgerber‚ G.‚ & Pernicka‚ E. 1995). Mining is still one of the most prevalent industries throughout the world with there

It then flows into northern Idaho‚ then back into Canada and Kootenay Lake. Ultimately it joins with the Columbia River. Endangered species like the bull trout and the Kootenai

of green house gases and therefore the contribution of nuclear power plants to global warming is therefore relatively little. Between mining the uranium‚ refining and enriching fuel‚ and finally to building and operating the plant‚ a big 1‚250 250-megawatt nuclear facility produces an estimated 250‚000 tons of carbon dioxide during its lifetime. In contrast‚ coal-fired plants produce close to 2 billion tons of carbon dioxide every year in the U.S. alone while also emitting lots of other pollution:
