黄饼

采用氟化物挥发法从黄饼生产UF6的适应性

The applicability of fluoride volatility process to producing uf_6 from yellow cake

通过小型试验、台架试验和扩大试验，筛选出混合萃取体系的最佳组成，同时确定了以黄饼为原料制备核电级U3O8的工艺流程和工艺参数。

By bench scale test , pilot test and expanding test , optimum proportion of various constituents in the mixed extractant , and process flow and process parameters for preparing nuclear power level U_3O_8 using yellow cake as raw material is determined .

铀矿石堆浸浸出液用沉淀法回收铀时，对最终沉淀黄饼产品质量影响最大的杂质元素是Fe和Al等。

In this paper a novel method is presented for recovering uranium from leaching solution of uranium ore heap leaching by jarosite hydrogen peroxide two step precipitation .

通过编制专门的计算机程序，对黄饼产品分析结果进行数据处理和误差分析，找出误差来源，最终提出解决办法。

Data processing and error analysing for yellow cake products were discussed .

返晶浆沉淀工艺在黄饼生产中的应用

Application of precipitation process of returning slurry in production of yellow cake

它已经把黄饼转化为六氟化铀气体。

It has converted yellowcake into uranium hexafluoride gas .

黄饼的铀品位为60.3%。

The precipitation efficiency of uranium is 99 % , and uranium content of yellow cake is 60.3 % .

结果表明，该工艺生产的黄饼具有良好的沉降过滤和脱水性能。

The results show that the produced yellow cake by the new production technique has better performance of settlement , filtration and dehydration .

向伊朗出口有“黄饼”之称的提纯铀，将违反联合国因伊朗拒绝冻结铀浓缩计划而实施的制裁规定。

Exports to Iran of purified uranium known as " yellowcake " would breach United Nations sanctions imposed on Tehran for refusing to freeze its uranium enrichment programme .

新工艺投资省、操作简单、消耗低，它比用离子交换法及溶剂萃取法提纯并最终制取黄饼的工艺更具有竞争力。

To take it as producing yellow cake will save investment , simplify operation , and cut down the consumption of raw materials and energies . It is more competitive than ion-exchange or solvent extraction in the process of extracting-purifying and preparing yellow cake .
