Abstract： This article describes the use of inductively coupled plasma optical emission spectroscopy （ICP-OES） to determine the levels of harmful elements in copper concentrate. It also discusses the assessment of measurement uncertainty by considering factors such as repeatability， volume adjustment， working curves， dilution of standard solutions， sample weighing， and the influence of the inductively coupled plasma optical emission spectrometer. These analyses provide a basis for the evaluation of uncertainty in the determination of harmful elements in copper concentrate.

Keywords： copper concentrate； harmful elements； inductively coupled plasma emission spectroscopy； uncertainty
