Koncentrate të bakrit, plimbit, sulfidit të zinkut - Përcaktimi i përmbajtjes së bakrit- Metoda titrimetrike

Copper sulfide concentrates — Determination of copper content — Titrimetric methods

Scope

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), titrating free iodine isolated by reaction between iodide ions and copper(II) ions with sodium thiosulfate using soluble starch as the indicator after separation (method 1) or without separation (method 2) of copper from interfering elements.
