| titleOfInvention | A kind of selectivity for regenerating the refining of lead bullion protects tin agent and application method except antimony arsenic |
| abstract | A kind of selectivity for regenerating the refining of lead bullion protects tin agent and application method except antimony arsenic, belongs to the refining removal of impurities field of regeneration lead bullion.The antimony arsenic guarantor's tin agent that removes is made of on the basis of its gross mass the lead powder of the aluminium of 10~30wt%, the calcium of 65~85wt%, the coke powder of 1~10wt% and 1~5wt%.According to the content of antimony in lead, to protect tin agent temperature is added according to a certain percentage except antimony arsenic be to carry out reacting except antimony, arsenic in 550~650 DEG C or so lead liquid by above-mentioned, antimony arsenic dross is pulled in cooling, which out, after reaction must remove antimony, arsenic lead liquid, and antimony arsenic content is reduced to 0.0005wt% hereinafter, Theil indices are basically unchanged.The antimony arsenic provided by the invention that removes protects tin agent to the removal efficiency height of antimony arsenic in lead liquid, it realizes and the depth of impurity antimony arsenic is removed, effectively remain valuable metal tin, reduce the production cost of metal preparation, except antimony, in arsenic reaction process, smoke-free and tasteless, working environment are good simultaneously. |
