从含铂废耐火砖中回收提纯铂及制备超细铂粉工艺研究

Study on Recovery and Purification of Platinum from Waste Refractory Bricks and Preparation of Ultrafine Platinum Powder

提出了一种从含铂废耐火砖中回收提纯铂的全湿法工艺,使铂的回收率达99%以上,纯度达99.99%。制备的铂粉平均粒径为0.66μm。

A selective leaching process of recycling and purifying platinum from waste refractory bricks is given in this paper. The results show that over 99% of platinum has been recovered, of which purity reaches 99.99%. The average size of Pt powder prepared is 0.66μm.
