European iron and steel enterprises to enter the iron ore market that the "buyer's market" and insisted the price should come down to 2005 levels, which means that mine operators in Brazil's CVRD Carajas mineral powder the need to reduce the price of 54%.

欧洲钢铁企业认为铁矿石市场进入&买方市场&，并坚持价格应回落至2005年的水平，这意味着巴西矿商淡水河谷的卡拉加斯粉矿的价格须减少54%。

Modest quantities of coltan and cassiterite have also been produced and exported during the past eight years.

In the pH range of 6~12, the results of the flotation tests indicate that the performance of the new combined cationic collector (CS3:CS1=3) and (CS3:CS2=2) is similar, and they are effective collectors for reverse flotation of the iron ores. The combined cationic collectors exhibited the same collectability as dodecylamine, but better selectivity than dodecylamine. By using the combined collector, the dosage of the collector decreased from 1 10-4mol/L to 1 x 10-5mol/L .

单矿物可浮性试验结果表明，在pH=6～12的范围内，新型组合药剂CS_3：CS_1=3和CS_3：CS_2=2具有相近的药剂性能，在其捕收能力与十二胺相当的前提下，不但选择性较十二胺好，而且还能显著提高药剂的协同效应，使药量从单用时的1×10~(-4)4mol／L降至1×10~(-5)mol／L，是铁矿石反浮选的高效捕收剂。
