摘要
现行离子型稀土地质勘查规范,与专门针对该矿种的提取工艺技术互不协调,出现一些问题.其中最主要的问题是矿床评价对象不恰当地规定为"全相"稀土,而目前真正可利用的"离子相"稀土,未具体评价,一般工业指标亦以"全相"稀土为依据,规范所确定的评价对象缺乏针对性和实用性.执行该规范将导致以下后果:以"全相"指标计算的稀土储量(资源量)大,而可利用的"离子相"稀土只是其中的一部分,相当一部分所谓的储量(资源量)没有工业利用价值;"离子相"稀土储量(资源量)估算不准确;矿床评价结果,在某种程度上可能误导宏观决策,困扰其后的开采与储量管理工作.另外,该规范规定的矿石"可选性"研究内容,不适应现行提取工艺,不能互相兼容;勘查工程布置缺乏灵活性、适用性;缺乏快速、简便、经济、适用的勘查手段.文中着重针对评价对象和一般工业指标问题进行了探讨,提出了修订建议,并从工艺角度出发,提出地质勘查工作的重点.
The current ionic adsorption rare earth geologic exploration specifications are not in concert with the extraction technology specifically designed for the mineral,which has caused some problems.One of the main problems is that mineral deposit evaluation object is ascribed as ＂whole-phase＂ rare earth inappropriately;while no specific evaluation goes to the truly available ＂ion-phase＂ rare earth at present.The general industrial indexes are based on ＂whole-phase＂ rare earth,and the evaluation object lacks pertinence and practicability.The implementation of the specifications will lead to the following consequences： rare earth reserve（resource） calculated by ＂whole-phase＂ rare earth is large,while available ＂ion-phase＂ rare earth only accounts for part of it,with a considerable part of so-called reserve（resource） having no industrial utilization value;inaccurate estimation of the reserve（resource） of ＂ion-phase＂ rare earth;the result of deposit evaluation might mislead macro-level policy-making to some degree,causing trouble to the future exploitation and management of reserves.In addition,the ore ＂preparability＂ research content set by the specifications does not adapt to the current extraction process and is not compatible with each other;the general layout of reconnaissance project lacks flexibility and applicability;speedy,simple,economical and applicable reconnaissance means is in short.Evaluation object and general industrial index are discussed,and amendment proposal is put forward.The focus of the geologic exploration work is proposed from the perspective of technology.
