在铅锌矿的采选冶中,经常要同时测定铅、锌以控制生产。过去采用的化学分析法,流程长不太适用。我们经试验提出如下方法适用于铅锌矿中。原矿浮选铅锌精矿、尾矿及沸腾焙烧后的锌精矿中铅锌的连测,可用于铅锌矿中采选冶的生产控制分析,结果满意。本法是把试样用6N硫酸分解,使铅成硫酸铅沉淀,过滤后用络合法测定铅;而于滤液中加入1—2克氟化物掩蔽其它常见元素(在PH 2—3)后,用碘氟法测定锌。
Mining and smelting in lead-zinc mining, often at the same time to determine lead and zinc to control production. Chemical analysis used in the past, the process is not suitable for long. We have tested the following method is suitable for lead-zinc mine. The results also showed that the continuous measurement of lead and zinc in ore flotation lead-zinc concentrate, tailings and zinc roaster after roasting roasted can be used for the production control analysis of mining and metallurgy in lead-zinc mine. This method is the sample with 6N sulfuric acid decomposition, the lead into lead sulfate precipitation, after filtration complexation method for the determination of lead; and in the filtrate by adding 1-2 grams of fluoride masking other common elements (after PH 2-3) , Determination of zinc with iodine fluoride method.
