Method for synergistically recovering valuable metals in arsenic-containing waste tailings and waste residues

The invention relates to the technical field of tailings recovery, in particular to a method for synergistically recovering valuable metals in arsenic-containing waste tailings and waste residues, which comprises a box-type roasting furnace and a magnetic separation device arranged on the horizontal line of the left side of the box-type roasting furnace, and an adjusting device is arranged on the top surface of the box-type roasting furnace. A smoke dust collecting device is arranged on the outer horizontal line of the right side of the box-type roasting furnace, and a metal precipitation device is arranged on the horizontal line of the rear side of the box-type roasting furnace. According to the method for synergistically recovering the valuable metals in the arsenic-containing waste tailings and the waste residues, reaction solutions corresponding to the valuable metals are placed in different precipitation barrels in a metal precipitation device, and flue gas is guided into the metal precipitation device t
