一般认为,炼锰会产生锰危害,炼铅或铅接触才会引起铅中毒。然而,炼锰怎么会导致铅中毒呢?原来,锰矿石在地壳中不是独立存在,而是伴随着铁、铅、锌、砷等多种金属,只是锰含量相对高些。我们调查了一锰矿的贫锰矿石品位,锰含量为16-25%,铅含量为0.5-2.0%,砷含量为0.1-0.5%,锌含量为0.1-0.3%,镉为0.0015%-0.003%,铜为0.005-0.01%。上述结果表明,锰在地壳中不是独立存在的。由于在锰冶炼过程中,伴着铅首先被 Generally believed that manganese will produce manganese harm, lead smelting lead or lead exposure will lead poisoning. However, how can lead to lead poisoning caused by manganese? Originally, manganese ore did not exist independently in the crust, but with iron, lead, zinc, arsenic and other metals, but the manganese content is relatively high. We investigated the grade of poor manganese ore from a manganese ore with manganese content of 16-25%, lead content of 0.5-2.0%, arsenic content of 0.1-0.5%, zinc content of 0.1-0.3%, cadmium of 0.0015% -0.003% , Copper 0.005-0.01%. The above results show that manganese does not exist independently in the earth’s crust. As in the manganese smelting process, accompanied by lead was first
