The solution cont. The hose also contained a wear indicator wire, which helped the maintenance team better plan for hose replacement or rotation before any failures occurred. Furthermore, Weir Minerals engineers standardized the hose length to fit in every installation at IOC in order to reduce the number of spare parts needed to be stocked in the warehouse. The total cost and life expectancy for the hoses from Weir Minerals for all 14 screens at IOC was CAD$165,200 with an 18 to 24-month life span. The results Above: Weir Minerals hoses in preparation for shipment to customer The custom-designed hose provided by Weir Minerals far exceeded the wear life of all other competitors. The Linatex® 808 Hard Wall Mining Hose lasted as long as 3 years, while the competitor hoses failed at 3, 4 and 12 months performing the same application. When compared to the incumbent hoses at IOC, Weir Minerals hoses lasted more than 10x longer. Operators at IOC needed to replace the two incumbent hoses operating on one screen six times per year, while the custom Linatex® hoses had no maintenance or downtime related issues during the same time. Replacing the incumbent hoses with the custom Linatex® 808 Hard Wall Mining Hose will save IOC CAD$338,800 over 2 years for all 14 screens, not including the added downtime to replace the hose and the mill tonnage that would need to be cut back if there were two screens down simultaneously for hose replacements.

  • Preparing for Carbon Pricing: Case Studies from Company Experience
    TECHNICAL NOTE 9 | JANUARY 2015 Preparing for Carbon Pricing Case Studies from Company Experience: Royal Dutch Shell, Rio Tinto, and Pacific Gas and Electric Company Acknowledgments and Methodology This Technical Note was prepared for the PMR Secretariat by Janet Peace, Tim Juliani, Anthony Mansell, and Jason Ye (Center for Climate and Energy Solutions—C2ES), with input and supervision from Pierre Guigon and Sarah Moyer (PMR Secretariat). The note comprises case studies with three companies: Royal Dutch Shell, Rio Tinto, and Pacific Gas and Electric Company (PG&E). All three have operated in jurisdictions where carbon emissions are regulated. This note captures their experiences and lessons learned preparing for and operating under policies that price carbon emissions. The following information sources were used during the research for these case studies: 1. Interviews conducted between February and October 2014 with current and former employees who had first-hand knowledge of these companies’ activities related to preparing for and operating under carbon pricing regulation. 2. Publicly available resources, including corporate sustainability reports, annual reports, and Carbon Disclosure Project responses. 3. Internal company review of the draft case studies. 4. C2ES’s history of engagement with corporations on carbon pricing policies. Early insights from this research were presented at a business-government dialogue co-hosted by the PMR, the International Finance Corporation, and the Business-PMR of the International Emissions Trading Association (IETA) in Cologne, Germany, in May 2014. Feedback from that event has also been incorporated into the final version. We would like to acknowledge experts at Royal Dutch Shell, Rio Tinto, and Pacific Gas and Electric Company (PG&E)—among whom Laurel Green, David Hone, Sue Lacey and Neil Marshman—for their collaboration and for sharing insights during the preparation of the report.

  • Rio Tinto Group from Wikipedia, the Free
    Rio Tinto Group From Wikipedia, the free encyclopedia Rio Tinto (LSE: RIO) is a multinational mining and resources group founded originally in 1873. The group is one of the world's largest mining companies, with a pre-tax profit of approximately 10.2 billion US dollars in 2006 on consolidated turnover of 25.4 billion USD. Since 1995, Rio Tinto has been a dual listed company. Rio Tinto Limited, formerly known as CRA, is listed on the Australian Stock Exchange, with Rio Tinto plc (formerly RTZ) listed on the London Stock Exchange as well as New York Stock Exchange (under ticker RTP). The two companies are managed as a single economic unit by a unified board, with a share in either company entitling the owner to the same voting rights and dividend payouts. RTZ shareholders made up 76.7% of the new unified entity, which is primarily managed from London. Its current chief executive is Leigh Clifford and the company board is chaired by Paul Skinner. History Rio Tinto's origins are in southern Spain, at the site of an ancient mine which supplied the Roman Empire. In 1873 N M Rothschild & Sons of London and de Rothschild Frères of Paris joined with other investors to acquire the Spanish government's money-losing Rio Tinto mines. The new owners restructured the company and turned it into a profitable business. By 1905, the Rothchild interest in Rio Tinto amounted to more than 30 percent. In 1962 the (British) Rio Tinto Company acquired a majority stake in Consolidated Zinc, an Australian company, and was renamed the Rio Tinto-Zinc Corporation (RTZ).

  • Its Your Turn: How Small- to Mid-Tier Mining Companies Can Win the Innovation Race
    Indian Oil & Gas Exploration and Production: Catalyzing Growth through Business Model Innovation | 1 Its Your Turn: How Small- to Mid-Tier Mining Companies Can Win the Innovation Race Satish Rao | Partner, Clareo rior studies have highlighted the challenges to ramp up productivity in the Mining sector. P Mining companies are struggling to be sufficiently profitable and to satisfy investors with the returns on capital, despite prices being 3 to 5 times higher than the lows of 2000. While pricing and increased extraction of deeper or lower grade ore are contributing factors, a significant threat to mining’s growth is its innovation deficit: the lack of application of technologies proven in other industries, and the slow speed from idea to adoption and scale. This is exasperated by recent events such as Vale’s tailings dam collapse in Brazil at Córrego do Feijão, which resulted in the deaths of an estimated 300 people and highlighted the significant safety challenges for mining companies. This is in addition to other health and safety risks, such as diesel emissions, water scarcity and pollution, dust, noise, and chemical hazards.

  • The Mining Engineer the First MS&T-UMR
    The Mining Engineer The first MS&T-UMR-MSM Engineer Newsletter for the Mining Engineering Program October 2008 December 2007 Graduates May 2008 Graduates This issue of The Mining Engineer is dedicated to our graduates. In December 2007 the last “UMR” graduate walked across the stage during commence- ment. This University started in 1870 as the Mis- souri School of Mines (MSM) and the first graduates were mining engineers. It was only befitting that the last UMR graduate was also a mining engineer. Alex Hofstetter, proudly wearing his hard hat, light and light belt, was the last undergraduate to walk across the stage in December 2007 to accept the con- gratulations by Chancellor Carney. Alex is working for Barrick in Elko, NV. Enrollment and Capacity Expansion: FS 2007 started with 33% increase in overall enrollment over the 2006-07 academic year. The total enrollment was about 215, which included 150 undergraduate and 65 graduate students. The program also graduated 25 mining engineers in the December and May Commencements. A number of program initiatives including the Summer Explosives Camps, Jackling Introduction to Engineering, and aggressive introduction of the program to the public contributed to this increase. The key to sustaining and growing this enrollment capacity is to provide the appropriate resources to train and educate the students. Toward this objective, the Department is planning a Capacity Renewal Conference to bring our alums and supporters to campus in April 2009 to discuss and develop a plan for reinvestments in critical areas of the program. The Department is also looking to boost the recruitment efforts by recruiting a Resident Recruiter for Mining Engineering.
