低品位铁矿资源开发经济分析模型与应用研究

随着铁矿资源选冶技术水平的提升,在国内消费不断扩张及市场价格不断高涨的情况下,使得低品位铁矿资源开发利用的时机日益成熟。通过引入经济品位概念,从量上界定了低品位铁矿资源的具体范畴;以盈亏平衡为基点,导出了计算低品位矿产资源开发利用临界品位的经济分析模型。在广泛收集相关参数及预计未来铁精矿价格走势的基础上,通过计算,从促进低品位铁矿资源开发利用角度考虑,认为我国低品位铁矿资源开发利用的临界品位定在17％是比较合理的。建议对铁品位在17％及以下的低品位铁矿资源开发实施优惠的激励政策;对铁品位在17％-23％的铁矿资源开发,在目前的经济技术条件下可以不需要政策优惠,但要注重政策引导.

Future copper resources

Concerns about future supplies of raw materials demand careful examination of underlying assumptions and data. Flawed deposit information, ignored undiscovered resources and questionable assumptions about future consumption require a new look at copper resources.A careful compilation of 1978 copper-bearing mineral deposits totals 2700 million metric tons of copper including past production—considerably more than reported in previous studies. About 69% of the copper is in porphyry copper deposits and 12% in sediment-hosted copper, Magmatic sulfide (mostly intrusive Ni) deposits account for 5.1%, and IOGC adds about 4.7%. VMS deposits represent 45% of the 1978 deposits but only 4.9% of the copper.The largest 20% of the deposits account for over 92% of the total copper metal. In other words, total Cu content in the smaller 1600 deposits is only about 8% of all Cu known in all deposits. This is a consequence of highly skewed frequency distributions of deposit tonnages and contained metals in all kinds of mineral deposits. This relationship is critical if one is concerned about long-term supply of copper. Typically, distributions of contained metal can be modeled well by the lognormal distribution for individual types of deposits.Information used here and in many other studies on copper includes past production. Total past production through 2015 is about 667 million tons Cu. After subtracting past production from the total copper in known deposits, the remaining unproduced copper from known deposits is 2030 million tons. Known deposits inform us about undiscovered copper resources.Over 80% of known copper is in porphyry copper and sediment-hosted copper deposits. A reliable and robust USGS managed global assessment of 225 tracts for porphyry Cu and sediment-hosted Cu produced an expected value estimate of 3500 million tons Cu in undiscovered deposits. Deposit types not assessed such as IOGC are likely to have significant amounts of undiscovered copper. If the proportion of total Cu accounted for by the two major deposit types assessed is the same proportion in all undiscovered deposits, total Cu expected in these other deposit types would add an additional 850 million tons. The reasonable estimate of copper in undiscovered mineral deposits of 4350 million tons when added to the unmined 2030 million tons in known deposits provides an estimate of 6380 million of tons Cu, which far exceeds estimates published by other researchers.Growth in copper production appears to be exponential over time but appears to be linear with respect to population. Demand for copper is not driven by time, but rather by population and per capita income. Rates of population increases are slowing and incomes in many countries are increasing. Per capita consumption of copper will increase over the coming years as populous nations such as China and India develop increasing per capita incomes, but the demand will likely level off as their economies improve. The large estimated copper resources along with evidence of slowing demand for copper over the long term considerably extend the time of “peak copper” and the long mine life of large deposits means the decline in production after will not be rapid. The focus of copper supply concerns should be on important problems such as improving recovery rates, careful consideration of the benefits and costs of mining very large deposits, technologies to increase exploration success in covered areas and reducing costs of underground mining.     

Marine mineral resources

Oceanic manganese nodules, for long the cornucopia of sea floor mineral deposits, have lost much of their economic attractiveness in recent years as a result of depressed metal prices and difficulties surrounding their potential extraction under the Law of the Sea Convention. In their place, commerical interest in mineral deposits within Exclusive Economic Zones has increased, while the scientific world is enamoured with the black smokers discharging at mid–ocean ridges and the polymetallic sulphides that precipitate from them.     

Mineral resources of the ocean

Major data concerning the history of investigation, distribution, mineral and chemical composition, and formation processes of mineral resources of the ocean, namely ferromanganese nodules, ore crusts, phosphorites, and hydrothermal mineral formations, including ore-bearing and metalliferous sediments, massive sulfides, and hydrothermal ferromanganese crusts are reviewed. The problem of the scale of mineral accumulations in the ocean and their quality, along with prospects of their future recovery, is discussed.     

Metallic mineral resources of Greece

Today Greece produces and exports raw bauxite and alumina, concentrates of galena and sphalerite and ferronickel. The indicated reserves of bauxite, located in the Mt Helikon-Mt Parnassus-Mt Giona-Mt Iti zone, are estimated at approximately 100 mt and those of aluminum 2.5 mt. The probable and indicated reserves of lead and zinc from Chalkidiki are approximately 3.125 mt. The total production of concentrates of galena and sphalerite is approximately 220,000 tpa. The proven reserves of nickel are approximately 1.392 mt and the production of ferronickel is approximately 18,500 tpa. Production of copper, silver and gold is pending in 2015. The probable and indicated reserves of copper from Skouries Chalkidiki are approximately 1.943 mt. In the Prefecture Units of Chalkidiki and Evros the probable and indicated reserves of gold are approximately 19.37 million ounces and those of silver 131.6 million ounces. Chromium, manganese and molybdenum present good prospects of exploitation. Calculated at current prices, the total gross value of the probable and indicated reserves of the metallic minerals of Greece is ?79.4 billion.
