...Should We Mine This Ore? Names CHM113 TA Name Class Time Introduction One of the most important skills to have in the chemistry lab is the understanding of how chemicals will react. Knowing for example, how a chemical will react with a metal, is an excellent way of determining the amount of a particular metal in a deposit. This knowledge was used in this lab to determine the amount of copper in an unknown sample mixture. It is also known that the determination of the percent concentration of a certain solution, will directly effect the percent transmission and absorption of a solution, dependent upon its dilution. By first testing known concentrations of a solution, and plotting this information graphically, a line is formed and a slope determined. That mathematical data of known mixtures can be used to determine the unknown solution by comparison. Materials & Procedure Materials: Colorimeter, Cuvettes, Balances, Spatula, Pipets, Processed Copper Ore, Cu(NO3) 3H2O(s), Diluted water, 2* 50ml beakers, 2*Test Tubes, Centrifuge machine Method: First Calibrate the colorimeter next Fill one clean cuvette with DI water then Set colorimeter to 635nm wavelength.

...planet. A prerequisite of sustainable development must be to ensure uncontaminated streams, rivers, lakes and oceans. There is growing public concern about the condition of fresh water in Canada. Mining affects fresh water through heavy use of water in processing ore, and through water pollution from discharged mine effluent and seepage from tailings and waste rock impoundments. Increasingly, human activities such as mining threaten the water sources on which we all depend. Water has been called “mining’s most common casualty” (James Lyon, interview, Mineral Policy Center, Washington DC). There is growing awareness of the environmental legacy of mining activities that have been undertaken with little concern for the environment. The price we have paid for our everyday use of minerals has sometimes been very high. Mining by its nature consumes, diverts and can seriously pollute water resources. Negative Impacts While there have been improvements to mining practices in recent years, significant environmental risks remain. Negative impacts can vary from the sedimentation caused by poorly built roads during exploration through to the sediment, and disturbance of water during mine construction. Water pollution from mine waste rock and tailings may need to be managed for decades, if not centuries, after closure. These impacts depend on a variety of factors, such as the sensitivity of local terrain, the composition of minerals being mined, the type of technology employed, the skill...

The mineral sector’s operations include mining and quarrying. Several projects have recently been completed including: an economic feasibility study on silica ore in Wadi Buwa and Abutan in the Wusta Region, which confirmed that there were exploitable reserves of around 28 million tonnes at the two sites; a feasibility study on the production of magnesium metal from dolomite ore; a draft study on processing limestone derivatives; a project to produce geological maps of the Sharqiyah Region (Ibra); economic feasibility studies on the exploitation of gold and copper ores in the Ghaizeen area; a study on raw materials in the wilayats of Duqm and Sur for use in the Sultanate’s cement industry; and a study on the construction of a new minerals laboratory in Ghala in the Governorate of Muscat The sultanate produces copper, chromite, gold, and silver. Oman's main copper reserves are in the Suhar area on the Al Batinah coast. The processing of ore at the Suhar complex, operated by the government-owned Oman Mining Company, began in 1983. The production of chromite by the Oman Mining Company also began in 1983 in the Suhar area. Exports of the Oman Mining Company are primarily destined to the Far East market. In 1990 Taiwan accounted for 38.5 percent of exports, followed by Japan with 11.1 percent...

...Baffinland Iron Mines Corporation Set in 2010 against the backdrop of the global iron ore industry, the case is about Baffinland Iron Mines Corporation, which is caught in a tug of war between Nunavut Iron Ore Acquisition Inc. and Arcelor-Mittal. Both Nunavut and Arcelor-Mittal have their eyes set on Baffinland's Mary River project, which consists of seven deposits and reserves of 865 million tonnes of high grade, direct shipping iron ore in deposits 1-3 alone. The Mary River project has been hailed as one of the best undeveloped iron ore deposits in the world. However, with the onset of the global financial crisis, the project fell on hard times and owing to a lack of financing partners, Baffinland found itself unable to move forward with the project's development. Between October 2007 and September 2010, Baffinland's share price plummeted almost 90% from $4.68 to $0.56 and seeing this as an opportunity to secure ownership of a lucrative asset that was currently trading at a discount, Nunavut made a bid to acquire all shares of Baffinland at $0.8 per share, valuing the company at $274 million. The offer was met with much consternation from Baffinland's board, which set out to look for alternative bidders. High on its list was Arcelor-Mittal and what ensued was a series of competitive bids. As of December 2010, Nunavut had raised its bid price to $1.35 per share for a 50.1% stake in Baffinland and was offering shareholders 2% royalty on the potential sale of iron ore. Pitted against...

...(20344878), An Li Xu (20341923), Jeffrey Wang (20342506) Subject: New Earth’s South Africa Iron Ore Investment Analysis ______________________________________________________________________________ New Earth Mining Inc. (“New Earth”) has substantial investments in the precious metals industry, specifically gold, but is facing volatile gold prices that may not be sustainable in the future. In response to this threat, New Earth should consider opportunities to diversify its business through exploration activities for other minerals. Attractive Investment for New Earth New Earth should take the opportunity to invest in the iron ore deposits in South Africa due to the following reasons: 1) It is a stable investment with long-term prospects of 15 years and a floor price of $80 per metric ton, and 2) The NPV of the project is $181.75 million, thus providing enough cash flows to cover debt and provide dividends to shareholders. Stable Iron Ore Investment The iron ore investment satisfies New Earth’s desire to diversify its business from precious metals with this potential investment life of 15 years. Prices are expected to stay over $80 per ton, with ore prices having reached a high of over $100 per metric ton in 2012. Production costs are expected to be low due to the easy access to ports from the mine location, reducing the need for infrastructure investment to support the development of the mine. Crude steel production in three Asian countries (i.e. China, South Korea, and Japan) are...

...INTRODUCTION This memo addresses the feasibility of the NESA project and provides a brief overview of: our financial condition, the iron ore market, major risks associated with this project, estimated project NPV, and the benefits of the financing packages. From our analysis, the NPV of this project is $137.36M - $104.31M. While there is risk associated with venturing into an unfamiliar market in a politically volatile country, the debt financing packages mitigate this risk. Thus, we believe that the project should be accepted. FINANCIAL CONDITION We experienced growth in earnings from $98M in 2002 to $1.84B in 2011, due to improved operating margins (Appendix 1). The improvements in ROE and ROA have outpaced our competitors, implying that we are getting higher returns for each dollar invested in shareholder’s equity and assets. Although we have a more aggressive debt strategy, our D/E ratio never exceeded 50% from 2002 to 2011. Despite the slight 4% decrease in our cash and current ratios, their values are still well above one. We are still in a good financial position as we have accumulated a lot of cash and our debt is being used effectively to take advantage of investment opportunities. Therefore, we are in an excellent position to take on new projects. NEW INVESTMENT OPPORTUNITY AND ASSOCIATED RISKS The iron ore investment in South Africa is an attractive opportunity since it allows us to diversify our operations and lessen our dependence on unsustainable gold...

...SAG MILL GRINDING DESIGN VERSUS GEOMETALLURGY – GETTING IT RIGHT FOR COMPETENT ORES J Starkey1 and P Scinto2 ABSTRACT Smarter processing for the future, in the area of SAG mill design involves accurate grinding test data, completing final mill design in less than three months, and at a cost of less than $80 000 US. More detailed variability testing on the other hand takes longer, is more expensive, and is used for throughput optimization for an existing or newly purchased mill. This paper shows that SAGDesignTM testing is excellent for new SAG plant design due to relatively low cost per test and the ability to do more testing for a limited budget on larger projects. It also briefly examines a way to develop proper geometallurgical ore hardness information on every block in the mine model, from the more detailed analysis data. Keywords: comminution tests, bond work indices, grinding mill design, database, ore hardness measurements, SAGDesign test, JK dropweight test INTRODUCTION The selection of SAG and ball milling sizes and configurations for new projects is complicated by the fact that grinding characterisation data is typically limited at best. The use of this grinding characterisation data by different grinding consultants, to specify totally different equipment and or configurations for the same project is becoming a major concern for the industry. This is highlighted by the fact that a number of new projects are following the concept of selecting the largest proven equipment...

...Copper is extracted from its ore using many different methods depending on the ore itself. The process includes heating it up with silicon dioxide or and oxygen in a furnaces and then the parts of copper in the chalcopyrite are made into copper sulphide which then is made into metal copper then the sulphur in the chalcopyrite is created into sulphur dioxide which is used to make sulphuric acid and the equation for all this is known as 2CuFeS2 + 2SiO2 + 4O2 ------> Cu2S + 2FeSiO3 + 3SO2. After all those steps the copper sulphide is finally transferred to copper with a gush of air the equation is CuS2 + O2 ------> 2Cu +...
