Environmental Geology - Assignment ExampleSulphides have a simple formula, and signal properties exhibited by metals, like luster and conductivity. Sulfides atomic number 18 identified by the anion S-2 (Britannica). Like Sulphides and sulfates, changes are in any case non-silicates. The carbonates are one of those exploitrals which are not localized and found in abundance and are distributed far and round-eyed (GeoSci). When a carbonate ion, CO32- , is present in any exploitral family it s referred to as a carbonate mineral.Iron sulphide, also known as pyrite has the chemical formula FeS. More commonly it is also referred to as the Fools Gold (GeoSci). It is found in Illinois, Wisconsin, Missouri, and Grant county (Galleries).Q. 2. There are a number of mines which have been developed in different parts of the world which now release dit mine drainage (AMD). For the following three mines or mine districts, 1) Iron Mountain Mine in Shasta County, Redding, California, 2) Britan nia Mine in Britannia Beach, British Columbia, Canada, and 3) the Rio Tinto mining district near Huelva, Spain, describe the years of operation, the type of ore mined, and the outstrip and nature of wastes generated from the mining activities.1. Iron Mountain Mine in Shasta County, Redding, California iron, gold, silver, zinc, copper and pyrite were mined. The mine operated from the 1860s up to 1963. The mine generated cadmium, copper, zinc, copper compounds, zinc compounds as wastes, which contaminated the Sacramento River. Richmond mine has the highest acidic mine water with pH values as low as -3.6, metal concentrates 200g/L, and sulphate concentrates 760g/L.2. Britannia Mine in Britannia Beach, British Columbia, Canada was a copper mine, which operated from 1900 to 1974. It also generated zinc sulphide and pyrite (Mills). intertidal discharge from the mine resulted in sub-aqueous deposits in Howe Sound, which was in excess of 44 million tones. Also 980 mg/l
