GB/T 8151.1-2012 《Methods for chemical analysis of zinc concentrates - Part 1：Determination of zinc content - Precipitate separation-Na2EDTA titrimetric method and extractive separation-Na2EDTA titrimetric method》 Related products

GB/T 8151.1-2012 specifies the determination method of zinc content in zinc concentrates, which is suitable for all kinds of zinc concentrates. Provide the settling separation Na -2 EDTA Titrimetric method and the extraction separation Na -2 EDTA Titrimetric method. The former first settles to separate the interfering elements, and then titrates the zinc with Na -2 EDTA; the latter separates the zinc from the interfering components by extraction and then titrates. The standard specifies the equipment, such as Burette, etc., and specifies the preparation of reagents. Detailed description of Sample Handling steps, standardizing the operation procedures of the two methods, including settling, extraction, titration, etc. According to this standard, the amount of zinc in zinc concentrates can be accurately determined, providing key data support for zinc concentrate mass evaluation and smelting process.
