Abstract: In order to the analysis of the phase of high gold-silver anode slime, the thesis does the research by the way of XRF, XRD, particle size analysis, scanning electron microscope analysis and so on. The research shows that anode slime has particle size and complex structure, which is rich in noble metals such as gold and silver, with a content of 10.42%. The main impurity metals are copper and lead, and their content are 17.26% and 13.28% respectively. The main phases of the gold include gold silver alloy and gold wrapped in copper selenide and lead sulfate with a small amount of silver and antimony. The main phases of silver include silver selenide, gold-silver selenide, copper-silver selenide, gold silver alloy, and silver wrapped in copper sulfate, lead sulfate. The main phases of copper exist in the form of copper sulphate. Copper sulfate is the base of anode slime with a large number of other impurity elements. The main phases of lead are mainly composed of lead sulphate, lead sulfate, and lead antimony arsenate with wrapped antimony, gold, silver, arsenic and so on. In addition, the anode slime also contains barium sulfate and antimony sulphate. This article analyses the composition and occurrence state of gold, Ag and main impurities of copper and lead in the anode slime in detail, which laid a foundation for the efficiency extraction of gold-silver process.
