Basic Information
Scope
Scope: This document specifies the chemical separation methods for niobium-bearing minerals such as calcites, pyroxenes, niobites, and carbonates, fluorites, and iron minerals in Baotou rare earth ores. This document is applicable to Baotou rare earth ores (primary ores) with a niobium pentoxide content of ≥0.05%. Main technical content: This standard takes existing technical methods as a reference, fully considering the current development and application status of niobium phase chemical separation methods and equipment, ensuring the effectiveness, reliability, and operability of the used technical methods and equipment, strengthening the standardization of text preparation, and guaranteeing the scientific and technological value and practicality of the standard. This standard includes nine content elements, namely: scope, normative reference documents, terms and definitions, method summary, reagents and materials, instruments and equipment, sample preparation, analysis steps, and quality assurance and control.
