一、前言元素赋存状态是矿床物质组成研究重要内容之一,它对于研究元素迁移结合规律、矿物、矿床形成条件、以及对矿床的工业评价,矿石选冶工艺指标及流程的拟定皆具有重大的理论及实际意义。对于稀有分散元素的赋存状态研究更具有重要价值。这是因为稀散元素往往对地质作用中元素迁移成矿过程的物理化学条件特别敏感,能较理想地指示矿物、矿床的形成等一系列地球化学问题。同时,由于它们在工业应用和国民经济中所占有的特殊地位,因而在矿床评价和矿石综合利用方面成为不可缺少,甚至是举足轻重的因素。
I. Introduction Presence of elements is one of the important contents of the study on the composition of mineral deposits. It is of great significance for studying the law of element migration and combination, the conditions for the formation of minerals and deposits, the industrial evaluation of the deposits, the ore processing and metallurgical process indicators and the process formulation The theoretical and practical significance. Research on the occurrence of rare dispersed elements is of great value. This is because the scattered elements are often particularly sensitive to the physico-chemical conditions of elemental migration and mineralization during geological processes, which can ideally indicate a series of geochemical problems such as the formation of minerals and deposits. At the same time, due to their special status in industrial applications and national economy, they have become indispensable and even pivotal in the evaluation of deposits and the comprehensive utilization of ores.
