Abstract

The invention discloses a method of preparing gold-silver alloy with precious antimony. The method comprises the following steps of sequentially adding a precious antimony raw material in a reverberatory furnace, a lead smelting furnace and a vacuum furnace, and performing the steps of precious antimony smelting, precious antimony impurity removal, precious antimony cupellating, lead adding, continuous cupellating, copper removal with sulphur addition, coarse lead preparation with condensation and the like to prepare the gold-silver alloy. By directly preparing high-value gold-silver alloy with the precious antimony, the method provided by the invention is short in technological process and relatively low in cost, is efficient and environmentally friendly, saves the energy, is the first invention in the antimony industry, has better application value and is worthy of large-scale popularization and use.

Description

【Technical field】 [0001] The invention belongs to the technical field of metal smelting, and in particular relates to a method for preparing gold-silver alloys from precious antimony. 【Background technique】 [0002] In the antimony industry, with the fluctuation of the antimony market and the consumption of single antimony raw materials, the processing capacity of antimony gold raw materials is gradually increasing. Precious metals such as gold and silver to obtain noble antimony containing antimony, gold, silver and other impurities. At present, reverberatory furnaces are usually used to treat noble antimony to improve the taste of gold and silver and obtain rich antimony. However, due to the high antimony content of this kind of rich antimony, it is easy to affect the recovery rate of antimony. The common method in China is to extract precious metals by chlorination. mine development. 【Content of invention】 [0003] The present invention aims to provide a method for p...
