一、锡矿的类型和成分我厂处理的复杂錫矿包括:高錫鎢矿精选产出的副产品錫尾矿和原矿略經粗选的毛錫矿。錫的品位較低,均含有鎢、鉍、銅、鉛、钼、铁、砷、硫和硅等杂质。根据主要杂质的含量可划分为高鉍-黑鎢-錫矿;高硫-黑鎢-錫矿;高砷-白鎢-錫矿;高砷-硫-錫矿;高钼-銅-錫矿和高鉛-鉍-錫矿等六种类型。其成分如表1所示。 錫矿石系由錫石、鎢錳鉄矿、鎢酸鈣矿、黄鉍矿、
First, the type and composition of tin mine complex processing of tin mine, including: high-tin tungsten ore by-product of selective tailings and rougher crude roughage roughage. Tin has a low grade and contains impurities such as tungsten, bismuth, copper, lead, molybdenum, iron, arsenic, sulfur and silicon. According to the main impurity content can be divided into high bismuth - black tungsten - tin; high sulfur - black tungsten - tin; high arsenic - scheelite - tin; high arsenic - sulfur - tin; high molybdenum - copper - tin And high lead - bismuth - tin and other six types. Its composition is shown in Table 1. Tin ore from the cassiterite, tungsten manganese 鉄 ore, calcium tungstate, yellow bismuth,
