Embodiment 1
[0015] The weight percent of the main chemical components of the treated precious antimony raw material is: Sb72.73%, Pb2.06%, Cu1.34%, Fe12.36%, Au content is 158.00g / t, Ag content is 2321.50g / t, It is processed through the following steps:
[0016] (1) Noble antimony smelting: According to the size of the reverberatory furnace, the noble antimony raw materials are added to the reverberatory furnace in batches, and the slag is removed after being filled; the reverberatory furnace is a commonly used antimony reverberatory furnace with a size of 12m 2 , the particle size of the noble antimony raw material is 50-100mm, and the weight added in each batch is 1.5-2.0t;
[0017] (2) Noble antimony impurity removal: add quartz sand to remove iron, the addition of the quartz sand is 2 to 4 times the total amount of iron impurities, and the iron content after the impurity removal is required to be <0.01%;
[0018] (3) Precious antimony ash blowing: After the iron content test meets th...
