镍钴高温合金废料湿法冶金回收

Hydrometallurgical Recovery of Waste Ni-Co Super-Alloys

由于高温合金废料中含有大量的镍、钴资源,如何使这些资源再生成为当今的热点话题。由于传统火法处理都存在金属回收率低、产品质量较差、生产成本高、环境污染大等缺点,因此用湿法冶金处理镍钴废料日益受到重视。本文简单介绍了高温合金废料的湿法冶金回收技术,包括合金废料的浸出处理技术和镍钴分离回收技术。

The super - alloy scrap contained large amounted of nickel and cobalt. How to make these to be renewable resources became a hot topic. Because of the low recovery rate, poor product quality, high production cost and environmental pollution for pyrometallurgy, hydrometallurgical process to deal with the nickel and cobalt waste took more and more attentions. The hydrometallurgical recovery technology of super - alloy scrap was briefly described, including the leaching processing technology, and nickel- cobalt separation and recovery technology.
