本文介绍了已知的第一批处理含铀炉渣的工业试验结果，这些含铀炉渣是在高炉冶炼含碳铁铀矿石（Zhovtorichenske存款，乌克兰）时获得的。结果表明，铁和铝杂质的分级沉淀可以减少铀的损失，提高硝酸盐氮和氨氮的利用程度，另外还可以生产硝酸铵作为肥料。化学精矿处理方案确保了成品中铀沉积程度的显著提高--高达60%。硝酸污泥处理技术可以保持水平衡，并完全防止向第聂伯河排放不平衡的废水。
The article presents the results of the first known industrial trials for the processing of uranium-containing slag obtained during blast-furnace smelting of carbonaceous iron-uranium ore (Zhovtorichenske deposit, Ukraine). It is shown that the fractional precipitation of iron and aluminum impurities allows reducing the losses of uranium and increasing the degree of utilization of nitrate nitrogen and ammonia nitrogen, additionally producing the ammonium nitrate as fertilizer. The scheme for chemical concentrate processing ensured a significant increase in the degree of uranium deposition into the finished product – up to 60%. Nitric acid sludge processing technology made it possible to maintain the water balance and completely prevented the discharge of off-balance effluents into the river Dnipro.
