1、摘 要本文是以黑钨精矿钨矿原料年产 1500 吨 APT（仲钨酸铵）生产车间的设计说明书。按照一般有色冶金生产车间设计步骤，文章首先概述 APT 生产的现状；结合原料特征，通过对 APT 整个工艺过程生产方法的比较，选择了苛性钠压煮法分解黑钨精矿离子交换法除杂和转型选择沉淀法分离钨钼连续蒸发结晶生产 APT 的工艺。根据所选的工艺特点以及黑钨矿的分布特点,选择了黑钨矿储量丰富的粤北地区阳山县作为厂区地址。通过对各生产工序金属平衡、物料平衡计算和设备选型，确定了各工序所需原料的量和设备的型号、规格和数目，并进行了合理的车间配置。通过分析生产过程中工业三废的来源和危害，提出了三废处理的方案；根据生
2、产过程需要，对车间进行了劳动定员。通过对整个工艺过程的技术经济分析，计算结果表明本设计所采用工艺流程技术上可行，经济上合理。投资回收期仅 1.43 年。关键词：关键词： 钨；黑钨精矿；APT；分解；浸出；离子交换；结晶；设计AbstractThe specification is a workshop of 1500t a year ammonium paratungstate(APT) produced with wolframite concentratesFollowing the general design steps of nonferrous metallurgy worksho
