In the good old days for steelmakers, that is there was one global price of iron ore, based on a free on-board quote before shipping, applying universally to all players in the steel industry, no matter where they were located.
SHANGHAI — Rio Tinto, the British-Australian mining giant, said Friday that it had joined two other global mining companies and decided to sell iron ore based on quarterly prices, a move that effectively ends a decades-old benchmark annual pricing system.
Depletion of phosphate rock is estimated to occur sooner than depletion of potash ore, based on the assumption that the amount of fertilizer used will increase by 3%% annually (Kuroda et al. 2005).
In contrast to these ore solutions, the composite ore-brine based on the Giordano and Barnes[39] MVT ore fluid (Table 10, Fig. 2 and 3) is comparable to the high salinity (> 170 000 mg L-1 TDS) subset of modern brines characterized by low trace-metal content and high total reduced sulfur (∑H2S) (Table 10, bottom half, right column).
The composite ore-brine based on the Giordano and Barnes (1981) MVT ore fluid is comparable to the high salinity (> 170 000 mg L-1 TDS) subset of modern brines characterized by low trace-metal content and high total reduced sulfur (∑H2S).
In addition, the one-way distances for a conservative estimate of silver ore concentration based on published in newspaper assays (m = 50 oz silver/ton or 0.05511 oz/kg) for both 20 and 45 kg loads are also calculated.
The move came soon after BHP Billiton and Vale said they had begun making iron ore deals based on quarterly prices, with BHP saying it had already made a significant number of deals with steel mills in Asia.
However, CISA pledged it would negotiate with BHP, Rio and Vale on iron ore imports based on the price settled with Fortescue.
The case for oil and commodities like copper and iron ore is based on China's gross domestic product rising from 6% to 10%.
