摘要：

目前稀土磷肥的生产都须在磷矿原料中单独添加稀土成分。贵州织金磷矿中伴生的丰富稀土因赋存状态差而难以通过常规的选矿方法进行分离提取而实现资源的综合利用。为探讨该含稀土磷矿在不单独另加其他稀土成分的条件下直接应用于稀土磷肥生产的可行性，首先深入研究了目前国内稀土磷肥的生产工艺并总结了稀土磷肥的共性，从织金磷矿的稀土存在形式、配分和含量以及放射性等方面进行评价。结果表明该磷矿中稀土的存在形式和配分较为符合稀土磷肥的生产要求，含稀土磷矿的放射性一般也都低于放射性标准500 Bq/kg，而织金磷矿稀土总量一般低于0.2%，可能更趋向于生产稀土低含量的稀土磷肥。从而从理论角度初步证实了织金含稀土磷矿可直接应用于稀土磷肥生产。

Abstract:

REE phosphate fertilizer is produced from phosphate material with added REE. Phosphate ore in Zhijin, Guizhou province, abounds in REE, but too hard to be recovered by normal processing. This paper, attempting at the feasibility of this phosphate ore to be used for producing REE phosphate fertilizer without adding other REE, reviews the processing technology of phosphate fertilizer, and evaluates the feasibility from REE occurrence, composition, content and radioactivity, which are all consistent with the requirements of REE phosphate fertilizer production. Radioactivity is less than standard 500Bq/kg, and the total content is 0.2%, means the ore fits for producing lowREE fertilizer. This paper theoretically verifies the feasibility of REEbearing phosphate ore can be directly used for production of REE phosphate fertilizer.

Key words: REEbearing phosphate ore, REE fertilizer, REE occurrence, component, content, radioactivity, feasibility, Zhijin
