高中英语人教版 精品系列课件,specialized english course for mineral processing techonology,mineral processing technologies: showcased at the cim conference,mineral processing methods are critical to the profitability of mine operation, particularly as customers demand higher production, reliability, efficiency and new features from processing equipment. some of the most advanced technology in the world for crushing, grinding, washing and separating ores were showcased recently at the cim conference and exhibition,held may 9 -12 in vancouver, canada.,vocabulary,cim(computer-integrated manufacturing) 计算机集成化制造技术 conference 会议；讨论会；协商会 showcased 被陈列的，被展示的 vancouvern. 温哥华（加拿大主要港市）,among the 418 companies exhibiting at cim the most ever in the events 27-year history, according to conference organizers were some of the industrys leading mineral processing firms. in talking to these companies, m found that a common theme is the need to design equipment that is efficient not only in terms of production rates, but also with respect to power and water usage. processing companies are also increasingly designing equipment with environmental factors in mind, as regulations around tailings and waste piles become more stringcorrecent.,vocabulary,mineral processing firm 选矿厂 m 国际矿业杂志 in terms of 在.方面 regulations. 条例；规程（regulation的复数）string,these findings are supported by mineral engineering technical services , an australia-based consulting group that recently outlined the coming challenges for the mineral processing sector. the group says that technological innovation will be a major challenge for mineral processing companies as they seek to overcome barriers to profitability, including: tanking base metals prices; tightened access to capital caused by the financial crisis, and the potential for a carbon trading scheme which is expected to add to the cost of processing ore.,vocabulary,australia-based 驻澳大利亚 outlined 概述，概括 consulting group 顾问团 innovation 改革 mets(mineral engineering technical services) 矿物工程技术服务中心,the imperative to reduce energy and water consumption is an equally important driver in the push to innovate, according to the group. “energy is a major cost for processing minerals and the comminution processes we use are inefficient and large consumers of energy,”says mets. the group forecasts a shift away from pyrometallurgical processing toward hydrometallurgical processing, and points to the long-overdue need for new grinding technologies.,vocabulary,imperativen. n.需要；命令；规则 comminution n. 粉碎；捣碎 overdue adj. 过期的；迟到的；未兑的,on water inputs, mets also sounds a note of caution. “desalination as a water source for processing will become more common for projects. water is going to become a scarce resource and access is going to be difficult with an emphasis on conservation and re-use.” all of this points to an increasing emphasis on innovation to overcome the challenges faced by the global mineral processing sector. what follows is a pic-ture of the mineral processing technologies presented at cim.,vocabulary,caution n. 警告。警示 scarce a. 缺乏的 conservation n. 储存 sound v.宣告，提出 desalination n. 脱盐作用；减少盐分,flsmidth,market leader flsmidth offers a range of equipment and technologies for mineral processing, including testing, design, engineering, crushing, grinding, classifying, flotation, thickening and clarifying, vacuum and pressure filtration, pyroprocessing, material handling, slurry handling, and automation.,vocabulary,thickening and clarifying 增厚和澄清 vacuum 真空 filtration 过滤 pyroprocessing 高温处理 slurry 泥浆 fore-front 最前沿 install 安装 multiple 多个 maintenance 维护 scavenger 清除剂 interchangeable mechanisms 互换机制,as the worlds largest supplier of flotation equipment, flsmidth is at the fore -front of the industry trend to install fewer, larger flotation units rather than multiple smaller cells, which saves the mine operator space, power and maintenance.,the companys 26 x 300m3 wemco cells were the first cells over 300 cubic metres to be installed in a new plant, and the first used in rougher/scavenger duty.the 350m3 supercell flotation machine, the argest flotation cell in the world, will allow for inter changeable mechanisms to suit any application while handling more slurry per hour than normalcells.,notes,no1.master the basic mining vocabulary no2.translation skills: transfer the p
