ISO 10258-2018 硫化銅精礦--銅含量的測定--滴定法 Copper sulfide concentrates - Determination of copper content - Titrimetric methods

This document specifies two titrimetric methods for the determination of the copper content of copper sulfide concentrates in the range 15 % (m/m) to 50 % (m/m), using sodium thiosulfate after separation (method 1) or without separation (method 2) of copper from interfering elements.rd edition 2018-02 Copper sulfide concentrates — Determination of copper content — Titrimetric methods Concentrés de sulfure de cuivre — Dosage du cuivre — Méthodes titrimétriques Reference number ISO 10258:2018(E) ？ ISO 2018 ISO 10258:2018(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2018 All rights reserved.
