Acid mine drainage Essays

Mines are important to civilizations because mining has provided metals that are used in the construction, transportations, energy, etc. Many important mines in Ontario can be found in Sudbury. However, mines pollute the environment by polluting the environment with acid mine drainage. Microbes speed up the process of leeching and oxidation in producing acid mine drainage. Nadia Mykytczuk, an environmental microbiologist in Sudbury, Ontario is investigating how microbes could be used to retrieve

The perioperative experience involves the preoperative, intraoperative, and postoperative phase. I had the opportunity to closely observe the health care staff during the last two phases of the perioperative process. This experience allowed be to gain a better understanding of the role of nurses throughout these different phases. It was apparent that their day to day duties are different than registered nurses in other areas of the hospital. During the perioperative experience, I was able to observe

There are 16 unique fountains spread across the city; fountains are called “pacchas.” They were used for drinking, and irrigation. In modern society, waterways are typically used for drinking and bathing, with the addition of recreational use e.g. surfing, water parks, washing dogs (a luxury the Inca’s did not have). The first fountain was built in Emperor Pachacuti’s suite. Also the emperor had a bathing room with a separate drain, so the shower water did not renter the water supply. The purist

Geography is one of the most important subjects that are taught ever since the primary classes. It consists of the study of our planet, its climatic conditions, the various landforms on Earth and the different natural occurrences. It also includes the spatial analysis of human and natural phenomena, the exploration of earth sciences and the study of the relationship between nature and human life. The study of geography includes the analysis of social, economic, and environmental processes that affect

families in the Bay, moving away, finding another means of survival, or abandoning traditional ways is simply not an option. The community is so immersed in generational traditions that to remove it would be a catastrophic detriment. This Pebble Mine operation if completed will be one of the most devastating violations of environmental justice that the

The Living Situation Affects Carrie’s Moral Judgments In Theodore Dreiser’s Sister Carrie, Carrie Meeber, a young provincial girl without money, social status, and special ability, comes to glamorous Chicago alone. In such a poor condition, if she wants to chase her dream to live a high-level life in the urban, she must suit “the discipline of society” and it is like “the law of the jungle”. The city processes the cruel survival competition. Thus, she has to face two choices: “Either she falls

Lost Innocence is a major theme throughout in all three novels. Each novel portrayed it in different ways and each novels is also has a variety of other minor themes. When Liesel moves to Himmel street she befriends a young boy named Rudy. Throughout The Book Thief Rudy symbolises pure innocence. He never understands what is going on around him. He is know as the boy who is obsessed with the black athlete Jesse Owens. One day he paints himself with charcoal and runs around a field. His father catches

World War I was one of the very first wars that had a global effect on the whole world. According to the book about WWI, The Guns of August, A shocking 32 countries took part in it. In the very first stages of WWI, the U.S stayed neutral, and had good reasons for doing so, too. However, the U.S eventually became entangled in the conflict anyway. Three leading causes forced the U.S to join WWI. The first reason was the sinking of the ship Lusitania. The second conflict was the sending of the Zimmerman

The river that I went to was in Krugersdorp, an area known for its bad acid mine drainage. The river had no fish in it and there as very little fauna and flora in and around the river. It was also a small stream and looked quite clean. This could mean that it was near its source and could have had a little bit of acid rain, since rain is more acidic due to the water molecules coming into contact with Carbon dioxide as stated by Milton Kazmeyer

sulfide ores. Minnesota 's traditional iron ore mining and sulfide mining are two very different types of mining. Sulfide mining has more environmental risks than Minnesota 's traditional iron ore mining. AMD (Acid Mine Drainage) is created from sulfuric acid. It 's created when sulfuric acid makes contact with metals and other chemicals from the disposal site and then it creates AMD. Amd does many terrifying things to the environment like, it contaminates lakes, rivers, ponds, and other bodies of

The Hurricane Creek Mine Disaster December 30, 1970 is the day everything changed for 39 families in the small town of Leslie County, Kentucky. The Hurricane Creek explosion was the most deadly coal mine disaster in eastern Kentucky history, and remains the most lethal mining disaster in America in the last 45 years(Lexington Herald Leader). The Hurricane Creek mine disaster was very devastating for the families, friends, and the one man that lived that day. The coal mines play a huge role in the

Introduction Pike River Coal Mine was established in 1982 and was the largest underground coal mines. In the 19th and 24th of November 2010, two methane explosions took place. Twenty nine men lost their lives in these explosions. Emergency services were put in place and mine crews from various places got involved. The absence of information provided about the conditions underground interrupted the rescue pursuit. This caused the Pike River Coal Mine to lose millions of dollars. In this report outlines

Metal detecting for gold nuggets is a pastime that is fairly new. The old time prospectors who searched for gold decades ago, never had any piece of equipment remotely like a metal detector. Modern technology however, has brought us this new device - the metal detector and modern prospectors are finding some significant gold that was previously overlooked. A detector is an electronic device, which can sense metallic objects buried in the ground. Since gold is certainly a metallic material, metal

titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌ H2CO3 The popping sound we hear when we open the can of fizzy drink, the bubbles and sparkle we see in the soft drink, and the feeling of bubble popping on your tongue, all of these are due

waters (Environment Canada 2012). Through a dual oxidation process, Nitrate is formed in a reaction of Nitrogen with Ammonium ion producing fertilizer and manure. The oxidation state of a nitrate compound is 1- . Nitrate is the conjugate base of nitric acid (HNO3), a strong

role of stomach acid Chapter 14 section 1 Noopur Rajendra Grade – 11AA 25/04/2016 Ms. Sara Kassem Sharjah American International School Discuss the role of hydrochloric acid in the digestion of foods. Point out how excess acid contributes to the discomfort known as indigestion. Explain how the stomach secretes a mucous layer, which protects it from being damaged by the hydrochloric acid it produces. Abstract Hydrochloric acid, which is also called HCl, is a highly corrosive acid. It is a strong

oxygen in extreme cases it could cause death. It could react with other chemicals causing more sickness. If you consume nitrate then you could just get small stomach flu, but when pregnant, or a baby it could cause much worse because your stomach acids are different.

The aim of the investigation was to determine the effect of pH on the rate at which catalase decomposes hydrogen peroxide and consequently answer the researchable question “How does pH influence cells and consequently an organism”. The hypothesis, “As the pH deviates from 7 the initial rate of oxygen production will decrease” is supported by the results. The trend displayed in Figure 3 is, as the pH deviates from 7 the initial rate of reaction decreases. Figure 3 shows that the rate of reaction (%O2/s)

The temperature of the water was then recorded to the nearest 0.1⁰C. Then the melting points of phenylacetic acid, o-anisic acid, and benzilic acid were determined by the use of a Mel-Temp. The unknown sample was obtained from the chemical stockroom. A small scale of crystals from unknown was placed in a test tube with the following solvents: cyclohexane, hexane, toluene, diethyl

The objective of the Bromocresol Green Equilibrium System Lab was to determine if the equilibrium constant, K, was a true constant at constant temperature. To determine this, the value of the constant was found at different concentrations of HIn, HIn-, and at varying pH, which was used to determine the concentration of H+. K was found using the equation K= [HIn]/([In-][H+]). In order to be a true constant, none of the values of K found should differ from the average by more than two standard deviations
