Gold Mining Case Study

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 (, 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
