Technical Field

The invention relates to the technical field of electrochemistry, in particular to a novel plate-shaped cathode.

Background

The high-arsenic antimony gold concentrate ore pulp electrolysis project is a novel technology for producing antimony by wet electrolysis, which is jointly developed by Beijing university of technology and New Shachen antimony industry Limited liability company, wherein the cathode adopted in electrolysis is a net-shaped titanium material, each cathode is formed by welding two specially-treated titanium nets, and the upper end of each cathode is in a full-welding form. In the use, often influence negative pole efficiency because electrically conductive effect is not good, and because of metal antimony is too big at negative pole electrodeposition deposit longitudinal stress to lead to shelling the antimony difficulty, in addition because netted negative plate bulk strength is low excessively, thereby appear damaging easily in the use, the maintenance degree of difficulty is big and the cost is higher, has produced certain influence to production.
