ISO 11441:1995 PDF Download

The back titration method is described in full in the ISO 11441:1995 standard for determining the lead content in lead sulfide concentrates. A standard solution is used to titrate the leftover EDTA (ethylenediaminetetraacetic acid) after precipitating the lead sulfate from the sample.

This standard is applicable to concentrations of lead sulfide with lead contents between 10% and 80% by mass. The technique guarantees precise determination of the lead concentration in these concentrates, enabling the mining and extraction industries to manage quality. Operators can confidently assess the lead concentration in lead sulfide concentrates by adhering to the prescribed protocol, which gives them the information they need to decide how to process and use these materials.
