乙硫氮学名为二乙基二硫代氨基甲酸钠,曾用名SN-9号,是一种铜试剂。产品呈白色结晶粉末状,性质稳定,易溶于水,无毒,含量在94%以上。浮选实践表明,乙硫氮对铜、铅、锑等金属硫化矿物捕收力强,对黄铁矿、磁黄铁矿捕收力弱,具有良好的选择性。是实现无氰浮选,综合回收贵重金属的优良捕收剂。其用量一般为丁黄药的1/2～1/3。(一)乙硫氮是实现无氰浮选的优良捕收剂广西大厂长坡选厂是应用乙硫氮最早的矿山之一,成功地将乙硫氮用于混合浮选的硫化矿粗精矿的无氰分离。
B thiosulfate named diethyldithiocarbamate, formerly known as SN-9, is a copper reagent. Products were white crystalline powder, stable in nature, soluble in water, non-toxic, content of 94%. Flotation practice shows that diethylthionine has strong catching power for metal sulphide minerals such as copper, lead and antimony and weak catching ability for pyrite and pyrrhotite, and has good selectivity. Is to achieve non-cyanide flotation, a comprehensive recovery of precious metals excellent collector. The dosage is generally 1/2 to 1/3 of butyl xanthate. (I) B Sulfur Nitrogen is an excellent collector for non-cyanide flotation Guangxi Dachang Changpo Sewage Treatment Plant is one of the earliest mines that use B and S, and successfully used B and S nitrogen in sulphide ore of mixed flotation Non-cyanide separation of concentrates.
