摘要
离子吸附型稀土矿床的稀土配分是决定矿床价值的重要因素,以ΣYO,Eu_(2)O_(3),Y_(2)O_(3)作为划分依据评价矿床经济价值目前已不合理。本文通过收集近3年稀土产品价格和40个离子吸附型稀土矿山配分数据,分析40个不同稀土配分的矿山价值,并进行对比研究,提出了以ΣYO,Pr6O11+Nd_(2)O_(3)和Tb4O7+Dy_(2)O_(3)为划分依据的稀土配分类型分类方案;根据6500件配分样品数据,提出6种主要稀土配分类型:高铽镝低镨钕重稀土、中铽镝低镨钕重稀土、中铽镝中镨钕轻稀土、中铽镝低镨钕轻稀土、低铽镝高镨钕轻稀土、低铽镝中镨钕轻稀土,并按照近5年稀土产品平均价格评估矿床经济价值,与实际市场定价进行对比基本吻合。该分类方案对合理评价离子吸附型稀土矿的经济价值具有一定的指导意义。
Rare earth partitioning characteristics of ion-adsorption type rare earth ore is an important factor determining the value of the deposit, and it is unreasonable to evaluate the economic value of the deposit on the basis of ΣYO, Eu_(2)O_(3) and Y_(2)O_(3). This paper collected the prices of rare earth products in recent three years and the partitioning characteristics of 40 ion adsorption type rare earth mines, analyzes the mine value of 40 different rare earth partitioning characteristics. A new classification scheme of rare earth partitioning types based on ΣYO, Pr6O11+Nd_(2)O_(3) and Tb4O7+Dy_(2)O_(3). According to the data of 6500 dispensing samples, six main types of rare earth partitioning types are put forward. The economic value of the deposit is evaluated according to the average price of rare earth products in recent three years, Compared with the actual market pricing, it is basically consistent. The classification scheme has a certain guiding significance for the reasonable evaluation of the economic value of ion adsorption type rare earth ores.
