Technical advantages of precious lead vacuum treatment
· Can remove lead, bismuth and antimony and reduce the sub-silver furnace blowing and slag production;
· Big equipment production capacity, shortened the production period of silver separation process, and increased the output rate of silver;
· Produce lead, bismuth and antimony in the form of alloy, depending on the content of components, directly high bismuth-lead electrolysis
or antimony removal process can be applied;
· Generally high direct recovery rate of element vacuum treatment, less mechanical adhesion loss, high metal comprehensive recovery
rate.
Technical advantages of precious bismuth vacuum treatment
· Completely replace the zinc-adding process to remove silver during the bismuth refining process, eliminate zinc consumption, and no
Applied Raw Materials silver and zinc slag generation, reducing production costs;
· Big equipment production capacity, greatly reduced the refining time;
