Copper sulfide concentrates — Determination of copper content — Titrimetric methods

ISO 10258:2018 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.

Concentrés de sulfure de cuivre — Dosage du cuivre — Méthodes titrimétriques

Bakrovi sulfidni koncentrati - Določevanje bakra - Titrimetrijska metoda

Ta dokument določa dve titrimetrijski metodi za določevanje vsebnosti bakra v koncentratih bakrovih sulfidov v razponu od 15 % (m/m) do 50 % (m/m) z natrijevim tiosulfatom po ločevanju
(1. metoda) ali brez ločevanja (2. metoda) bakra od motečih elementov.
