摘要： Molybdic oxide is recovered from molybdenite by a multistep process in which (A) the molybdenite is converted to soluble and insoluble molybdic oxide by pressure oxidation, (B) the insoluble molybdic oxide is converted to soluble molybdic oxide by alkaline digestion and then combined with the soluble molybdic oxide, and (C) the molybdenum values of the combined streams are extracted into an organic phase using a nonprimary amine. The extracted molybdenum values are recovered from the organic phase using aqueous ammonia to form ammonium dimolybdate (ADM) which is recovered as refined crystals from a two-step calcination process. Hallmarks of the process include one or more of economic ammonia recovery and recycle, use of ferrous sulfate to remove arsenic and/or phosphorus from the Mo-loaded aqueous ammonia strip liquor, two-stage calcination of ADM crystals, recovery of rhenium from a filtrate of the residual molybdenum precipitation stage, selenium removal from the liquid fraction from which rhenium is recovered, and caustic boil of the mother liquor from which the selenium is precipitated.
摘要翻译：通过多步法从辉钼矿回收钼酸盐，其中（A）通过压力氧化将辉钼矿转化为可溶性和不溶性氧化钼，（B）通过碱性消化将不溶性氧化钼转化为可溶性氧化钼，然后与可溶性氧化钼和（C）组合物流的钼值使用非主要胺萃取到有机相中。使用氨水从有机相中回收提取的钼值，以形成二钼酸铵（ADM），其由两步煅烧过程作为精制晶体回收。该方法的标志包括经济氨回收和再循环中的一种或多种，使用硫酸亚铁从负载氨的氨气条带液中除去砷和/或磷，对ADM晶体进行两阶段煅烧，从滤液中回收铼的残余钼沉淀阶段，从其中回收铼的液体馏分中除去硒，以及沉淀出硒的母液的苛性碱沸腾。

摘要： A process for the recovery of gold from a gold-bearing aqueous filtrate, the process comprising the steps of: (A) Contacting the aqueous filtrate with dibutyl carbitol (DBC) in a two-stage solvent extraction process to remove the gold from the aqueous filtrate into the DBC to form a gold-loaded DBC; and (D) Contacting the gold-loaded DBC with an aqueous acid scrub of hydrochloric acid in a four-stage countercurrent scrub process to remove impurities, e.g., non-gold metal, from the DBC into the aqueous scrub solution to form an impurity-loaded aqueous scrub. Each stage of the solvent extraction circuit and the aqueous acid scrub circuit is equipped with a mixing assembly and a phase separation tank in a head-tail arrangement such that the mixing assembly of one stage is adjacent to the phase separation tank of the adjacent stage.
