Problems solved by technology

The separation effect of sulfur and other substances is poor, resulting in low sulfur content of anode slime entering the dryer and melting tank, large material handling capacity, and thus high energy consumption
At the same time, crude sulfur is melted using normal pressure suction filtration, the recovery rate of sulfur is low, and the working conditions are poor.

Abstract

The invention discloses anode mud treatment equipment, which comprises an air flotation slot, a dryer, a melting slot and a sulfur filter press, wherein the dryer is connected with the air flotation slot and is used for receiving and drying crude sulfur discharged from the air flotation slot; the melting slot is connected with the dryer and is used for melting the dried crude sulfur; and the sulfur filter press is connected with the melting slot and is used for carrying out pressure filtration on the melted sulfur. The invention also discloses the air flotation slot used for the anode mud treatment equipment. According to the invention, three substances in anode mud are simultaneously separated in the same air flotation slot, less equipment is needed, and the separation effect is good. The sulfur content in the separated crude sulfur is high, and the energy consumption in melting is further reduced because the crude sulfur is dehydrated and dried before being melted. Since the sulfur content in the crude sulfur is high, and the sulfide content is low, the operation and the efficiency performance of the sulfur filter press become convenient.

Description

technical field [0001] The present invention relates to an anode slime treatment equipment and an air flotation tank thereof, in particular to an anode slime treatment equipment for recovering sulfur and sulfides rich in valuable metals from anode slime, a by-product of electrolytic production of nickel metal, and its Air flotation tank. Background technique [0002] Traditionally, the production of metallic nickel from copper-nickel sulfide ore has to go through many processes to separate nickel, impurities in the ore and other metals to obtain pure metallic nickel. The last process is the electrolysis process of nickel, in which the metal is precipitated at the cathode Nickel, while the sulfur contained in the anode and other valuable metals (such as platinum, lead, gold, silver, etc.) rich in sulfides (such as nickel sulfide and copper sulfide) remain in the electrolytic cell in the form of solid sludge , commonly known as anode slime. Anode slime contains a large amoun...
