本文選題：條帶狀鐵建造(BIF) + 高品位赤鐵礦　； 參考：《巖礦測試》2017年02期

【摘要】：國內(nèi)外鐵礦石價格對標基準多采用離岸價或到岸價,而非盈虧平衡運營成本,難以揭示我國鐵礦石所面對的真實市場承壓價格。為了厘清國際一線生產(chǎn)商的鐵礦石盈虧平衡運營成本價格,本文對世界上最重要的條帶狀鐵建造(BIF)礦產(chǎn)地——西澳哈默斯利盆地高品位赤鐵礦礦床的礦化特征及代表性鐵礦石產(chǎn)品展開系統(tǒng)研究,同時引入巴西鐵四角地區(qū)的鐵英巖型赤鐵礦礦石作為對照,分析全球典型高品位赤鐵礦礦石經(jīng)濟指標。結(jié)合前人研究成果,將西澳哈默斯利盆地與BIF相關的高品位赤鐵礦的富集礦化類型劃分為假象赤鐵礦-針鐵礦、微板狀赤鐵礦與河道沉積型赤鐵礦,巴西鐵四角主要為鐵英巖型赤鐵礦。上述各礦化類型對應的鐵礦石產(chǎn)品的鐵元素含量均高于56%;在雜質(zhì)元素含量上,假象赤鐵礦-針鐵礦的磷含量高,微板狀赤鐵礦的磷、硫含量較高,河道沉積型赤鐵礦的磷、硫含量較低,鐵英巖型赤鐵礦含錳。經(jīng)定量估算,西澳力拓、必和必拓、FMG和巴西淡水河谷的鐵礦石盈虧平衡運營成本價格分別為34.66、36.76、47.35、38.07美元/干噸,可為中國海外權(quán)益鐵礦項目開發(fā)提供運營成本的參考。
[Abstract]:Domestic iron ore price benchmarking benchmark by FOB or CIF, rather than breakeven operating costs, it is difficult to reveal the true market price pressure in China's iron ore face. In order to clarify the international line of producers of iron ore breakeven operating cost price, this paper built the iron strip of the world's most important (BIF) -- the systematic research of mineral deposits in Western Australia Hamersley basin high grade hematite mineralization characteristics and typical iron ore products, while the introduction of Brazil iron four corners area iron quartzite type hematite ore as control, analysis of the typical high grade hematite ore global economic indicators. The results of previous studies, divides the enrichment of mineralization the type of Western Australia Hamersley basin associated with BIF high grade hematite is martite goethite, hematite and micro plate river sedimentary hematite, Brazil iron angle four The main iron quartzite type hematite. Iron content corresponding to the various mineralization types of iron ore products were higher than 56%; the content of impurity elements, phosphorus content of martite goethite, hematite micro plate of phosphorus, sulfur content is higher, the river sedimentary hematite phosphorus, sulfur low content of iron, manganese containing hematite quartzite type. By quantitative estimation, Australia Rio Tinto, BHP, FMG and vale of Brazil iron ore breakeven operating cost price was $34.66,36.76,47.35,38.07 / ton, can provide reference for the operation cost of the Chinese overseas iron ore project development rights.
