The progress on the disposal and treatment of effluent and tailings from uranium mill and technical flowsheet without producing wastes is also introduced concisely.

还描述了由磷炔岩、褐煤、碳质页岩、含铀多金属矿及海水提铀的重大新进展，扼要阐述铀水冶的废水及尾矿处理和铀水冶的无废物工艺流程研究的新进展。

That is, U-enriched muscovite peraluminous granites are the uranium source for metallogenesis, and the uranium is mainly devided from the parent granite rocks weathered and denudated, not from the hydrothermal solution derived from the parent granite rocks.

即铀含量较高的晚期二云母过铝质花岗岩是铀成矿作用的铀源，而且，铀源主要来源于被风化并剥蚀掉的那部分母岩，而不是来源于热液流体对现存母岩的交代。

In order to study the reaction kinetics of uranium with CO or CO 2,uranium samples of different forms are obturated in reaction vessels and then CO or CO 2 is filled in. Gases in vessels are analyzed at different storage time.

在一定温度下，将不同形态的铀样品密闭贮存在容器中并充入一定压力的高纯CO或CO2 气体，通过定期测量贮存容器中气体组成，初步研究了铀与CO或CO2 的反应动力学。

Avalon Rare Metals, for example, owns a rare-metals property at Thor Lake in the Northwest Territories. Ucore Uranium, based in Halifax, has a project in southeastern Alaska. VMS Ventures optioned a uranium and rare-earth property in Manitoba. Billingsley's company, Great West Mineral Group of Saskatoon, owns the Hoidas Lake project on the northern fringe of Saskatchewan.
