最近,杜邦公司向埃里考特机械公司采砂船分公司订购一艘大型采砂船开采佛罗里达的钛砂矿。杜邦公司是世界上主要的TiO_2生产者和消费者。最近世界的TiO_2需求量增长,杜邦公司开始实施一项投资数百万美元的计划以扩大TiO_2生产能力。目前,已有两艘装备有选矿设备的采砂船在开采邻近的特莱尔里奇钛矿床,增加这艘新采砂船后,杜邦公司将把矿山开采年限延长到2010年。采砂船把钛砂泵送给浮船式选矿厂,分离出TiO_2和其他副产矿物后,再 Recently, DuPont ordered a large-scale sand-mining vessel for the production of titanium sands in Florida from the Yerevan Machinery Company Sand Dredging Division. DuPont is the world’s leading producer and consumer of TiO 2. With the recent increase in TiO 2 demand in the world, DuPont has started a multi-million dollar plan to expand its production capacity for TiO 2. At present, two sand mining vessels equipped with mineral processing equipment have been extended to 2010 after the mining of the nearby Tritrich Ridge Titanium Deposit and the addition of the new sand mining vessel. Sand mining vessels to the titanium sand pumped pontoon concentrator, the separation of TiO_2 and other by-product minerals, and then
