Abstract: An agent for selective antimony and arsenic removal and tin retaining includes 10-30 wt % of aluminum, 65-85 wt % of calcium, 1-10 wt % of coke powder, and 1-5 wt % of lead powder. According to the content of antimony in lead, the antimony and arsenic removal and tin retaining agent is added to a molten lead which is at a temperature of about 550-650° C. at a certain proportion so as to carry out an antimony and arsenic removal reaction; after the reaction is completed, cooling is carried out, and antimony and arsenic scum is fished out to obtain a molten lead with antimony and arsenic removed; the content of antimony and arsenic is reduced to 0.0005 wt % or less, and the content of tin is substantially unchanged. The production costs for lead alloy preparation are reduced, and no smoke and odor appear in an antimony and arsenic removal reaction process.

Abstract: A lead needle and lead slime separator for treating thin lead grid of waste lead-acid storage battery, includes: a barrel body, corrosion-resistant and wear-resistant balls, a feed device, a bracket device, a discharge device and a driver. A feed hole is arranged at one end of the barrel body, a discharge port is arranged at the other end of the barrel body. The feed device is mounted at the feed hole, and the discharge device is mounted at the discharge hole. The bracket device is connected to the barrel body, the driver is connected to the barrel body. The corrosion-resistant and wear-resistant balls are arranged in the barrel body. The separator can make the thin lead grid separation complete, clean and impurity-free. It does not need to be melted at high temperature in the melting furnace.
