一、前言玛瑙山锰矿是个以含铁、锰为主的多金属矿床,矿点较多,玛瑙山和玉皇庙是两个主要矿点。矿石中除含铁、锰外,还含有铅、锌、银、锡、铋、钨等元素。矿床储量较多,开采条件较好,具有综合利用价值。由于矿石结构上的特点,采用一般的选矿方法难于使铁、锰、铅等分离,为了充分利用资源,综合回收有用金属,寻求一条合理的途径,我们对该矿石进行了火法冶炼试验。另外玛瑙山堆存有数十万吨老炉渣,据说是清代土法提炼银的废 I. Introduction Anaoshan manganese ore is a ferrous and manganese-dominated polymetallic deposit with more ore deposits. The Anhai Mountain and the Jade Emperor Temple are the two major ore mines. In addition to iron ore, manganese, but also contains lead, zinc, silver, tin, bismuth, tungsten and other elements. More deposits, mining conditions are better, with comprehensive utilization value. Due to the structural characteristics of ore, it is difficult to separate iron, manganese and lead by using the common beneficiation methods. In order to make full use of resources and comprehensively recover useful metals, we seek a reasonable way to conduct pyrometallurgical tests on the ore. In addition there are hundreds of thousands of tons of old slags stored in the agate hill, which is said to be abolished in the Qing Dynasty
