目前处理钨精矿常用的工艺流程有四种:酸分解法、苏打烧结浸出法、烧碱浸出法和苏打高压浸出法。烧碱浸出法和苏打高压浸出法是其中最有效的方法,而这两个流程中又以苏打高压浸出法为优。这不仅是苏打比烧碱便宜易得,腐蚀性较弱,而且苏打浸出液中的杂质含量比烧碱浸出液中的杂质含量要低得多,这样就给以后的净化提纯作 At present, there are four commonly used processes for the treatment of tungsten concentrates: acid decomposition, soda agglomeration leaching, caustic soda leaching and soda high pressure leaching. Caustic soda leaching and soda high pressure leaching is one of the most effective methods, and in these two processes and soda high pressure leaching method is superior. This is not only cheap and easy to obtain than caustic soda, less corrosive, and the content of impurities in soda leachate is much lower than the content of impurities in caustic leachate, so that after purification purification
