用螯合树脂回收贵重金属新方法 本技术可用于回收废催化剂中的铂、铼、钯等贵金属。非矿石中的金、银、钌、钯、铂、铼、锇、铱(含阳极泥,CU阳极,Ni阳极,sb阳极),Ni等。CU矿阳极泥中金、银、钯、铂的回收。收率平均98％以上。 主要原料:树脂等。每公斤树脂价格为几百元不等。每公斤树脂可吸附1kg,金;0.4kg钯,0.4kg铂,0.3kg铼。而后洗脱,树脂可再生。每公斤树脂吸附总量为0.4kg贵金属,树脂可重复使用7-8次。 主要设备:反应釜、柱子、过滤装置、泵等,投资少,效益大。
New method for recovery of precious metals with chelating resins This technology can be used to recover precious metals such as platinum, rhenium and palladium in spent catalysts. Non-ore of gold, silver, ruthenium, palladium, platinum, rhenium, osmium, iridium (including anode slime, CU anode, Ni anode, sb anode), Ni and so on. CU ore anode mud gold, silver, palladium, platinum recovery. Yield average more than 98%. The main raw material: resin and so on. Per kilogram of resin prices for a few hundred dollars. Each kg of resin can be adsorbed 1kg, gold; 0.4kg palladium, 0.4kg platinum, 0.3kg rhenium. After that, the resin is regenerated. The total amount of resin adsorption per kg of 0.4kg precious metals, resins can be reused 7-8 times. Major equipment: Reactors, columns, filtration devices, pumps, etc., less investment, great benefits.
