Gold Mining Case Study

Decent Essays
Acid mine drainage has polluted the Tigithe River, which provides drinking water supply for more than 250,000 people. It was the main reason the Tanzanian Parliaments demanded the NMGM be closed in 2009, owing to the deaths of 40 villagers and their livestock (www.reuters.com, 2010). A study had conducted throughout the government accepted the "principle", and stated that there had been minimal environmental monitoring done in the area because the National Environment Management Council is quite small, with only 20 environmental inspectors for the entire country (Mutagwaba, 2006). As a result of low monitoring system, the water pollution is not only caused by acidic drainage of the company but also as by small-scale gold mining. In 2010, however, …show more content…
A combination of strong waste management policy and applied technology may result in a good tailing management of gold mining. The NMGM has an environmental policy statement and it needs to effectively implement in tailing management. The corporate social responsibility program of the company should take into account the environment issues. In addition, a fact that does not exist a comprehensive regulation, sites which have been designed, operated and closed using appropriate control measures of waste mining. The sustainable waste management policy might a framework for current pollution prevention technology is applied to the operation. A specific control measures are proving to be effective in retroactively controlling acid generation at some sites in combination with varied environmental features of the sites. Therefore, gold mining project must be evaluated in terms of the specific nature of the anticipated waste materials and its site characteristics in order to develop an effective waste management …show more content…
Controlling of technology and continuing research activity have been shown to be effective in management of mine wastes and also applied to the closure of existing facilities and reclamation of abandoned sites. However, at most of these sites, the control technology was implemented after the effectiveness of the control measures are reflected in a reduction of composed fine particles (sand, silt, and clay-sized material) and a high water content, which is particularly troublesome to manage. In response to tailing bad management and water contamination, the policy is in light of giving option to store the tailing in a dam. The dam design must be very technical, and takes a number of site-specific factors into consideration, such as flooding and earthquake predictions, seepage control, tailings discharge method and rate, and changes over the lifetime of the dams. Moreover, the water from the tailing dam can be recycled and reused for gold mining operation and dust suppression, or treated and discharged into the environment.
The sustainable waste water management regulatory approach for the NMGM’s waste facilities is essential to regulate such sites in accordance with the same technical criteria and principles as those applied to other solid waste facilities. One of the basic elements of this

    Introduction The Jackson Pike Wastewater Treatment Plant, located in Columbus Ohio, along with the Southerly Plant are responsible for treating a combined average of 208 million gallons of water per day [1]. Founded in 1937, the Jackson Pike Plant first treated approximately 50 million gallons of water per day. To keep up with a growing Columbus population, the wastewater plant has been upgraded to treat 150 million gallons per day. On September 7th, 2017 Carnell Felton, the plant’s assistant plant manager took myself and the OSU CBE 5761 class on a tour around the plant to demonstrate the water treatment process. Felton walked through the process how waste water from Columbus and 22 suburban comminutes is treated.…

    The Brukunga Mine site lies above Brukunga Township in South Australia, located 4km north of Nairre and 40km east of Adelaide, Mount Lofty Ranges. The operation of iron sulfide (pyrite and pyrrhotite) quarrying in Brukunga mine occurred between 1955 and 1972 (PIRSA, 2005). The manufacture of sulfuric acid in fertiliser industry caused the production of superphosphate fertilisers. The sponsorship from the state and federal government for the development of the mine provided employment and self-authority in local agriculture. During the operation, 5.5Mt of iron sulfide, 8Mt waste rocks and 3.5 tailings were produced.…

    *Both the communities of Shoal Lake 40 and the land surrounding the Marlin Mine have been environmentally affected which also affects the health of locals. In the surrounding areas of the Marlin Mine, there have been many complaints by locals that the water is being contaminated by toxic metals (Zarsky and Stanley 2013). Research encourages that there is this heightened level of metal in the river close to the mine, which puts the ecosystem and human health in danger (North and Young 2013). There is also evidence that acid from the mine is being drained close by, which could be why there are elevated metals in the water, aluminum, copper, and manganese (Holden and Jacobson 2008). Many Guatemalans have voiced their opinion on the issue but proposals have been…

    In the western world, environmental management and stewardship are key responsibilities of both public and private institutions. In U.S.A for instance, the Superfund insurance scheme was established under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) of 1980. The overall purpose of the fund was to provide protection to individuals and properties against the possible hazards arising from “potential polluter industries” and related facilities. As a requirement by federal government and related legal structures, the Superfund has worked to ensure that individuals living in close proximity to the polluter premises are well covered and protected. Moreover, superfund has taken into consideration all losses and adverse effects impacting the environment from polluter firms.…

    Tailing ponds are one of the greatest environmental challenges that the Oil Sands Industries of Alberta and other locations in the world face today. Tailing Ponds can be described as large “dump holes” in which the industry exposes of all the waste materials obtained from the refinement of Bitumen - a raw material which can be processed into oil. Tailing Ponds include many different types of waste materials such as water, fine silts, residual bitumen, salts and soluble organic compounds. They also include solvents that are added to the oil sands during the separation process. After the oil has been extracted from the sand the residue is dumped into the tailings and quickly settles to the very bottom.…

In the beginning, David was getting results from Frank’s waste water discharge tanks that showed that they have been releasing arsenic and lead at higher levels than what the city allows. The waste water ends up into the popular and profitable sludge product called Gilbane Gold. Gilbane Gold is sold as a fertilizer to farmers for about 75 years. David mentions his concern of this in the monthly meeting.…
