标准范围
本文件规定了测定铜、铅和硫化锌精矿可运输水分极限(TML)的流程表方法,这些精矿在运输过程中可能会液化。本标准适用于铅含量为10%至80%(质量分数)、锌含量为10%至65%(质量分数)或铜含量为10%至55%(质量分数)的精矿TML的测定,并适用于TML值在3%至28%(质量分数)范围内的测定。
This document specifies a flow-table method for the determination of the transportable moisture limit (TML) of copper, lead and zinc sulfide concentrates, which can liquefy during transport.It is applicable to the determination of the TML of concentrates containing 10 % to 80 % (mass fraction) of lead, 10 % to 65 % (mass fraction) of zinc or 10 % to 55 % (mass fraction) of copper and is applicable to TML values in the range 3 % to 28 % (mass fraction).
