用铅试金法分别对铜精矿,粗铜,镍精矿,低冰镍,高冰镍等冶金物料进行一次试金,将熔渣和灰皿进行二次试金,测得一次试金和二次试金所得贵金属合粒中的金量,得到一次试金中金的回收率。随样品中金量的增加,一次试金中金的回收率随之增加。 The lead test method was used to test gold, copper, nickel concentrate, low iced nickel, high iced nickel and other metallurgical materials respectively. The slag and ashware were tested twice, The amount of precious metal in the gold obtained from the gold test, get gold gold gold recovery rate. With the increase of the amount of gold in the sample, the recovery of gold in a gold test increases accordingly.
