针对某金矿厂金泥生产过程中存在的问题：坩埚使用寿命低，熔炼产品合金中金银品位低及渣含金高，金收率低等，提出了金泥酸浸除锌、浸渣再熔炼，一步获得金银合金的新工艺同时研究了硫酸加入量、浸出时间对锌浸出率的影响．试验结果表明，采用该新工艺不仅能消除锌对熔炼过程的危害，延长坩埚使用寿命，而且可将锌回收．当硫酸加入量为理论量15％～17％，浸出时间不少于80min，固液比1：3时，锌浸出率≮95％．含金浸渣在适宜条件下进行熔炼，渣含金可降低至40g／t左右，金收率达998％以上.
Aiming at the problems existing in the gold mud production process in a gold miner, the crucible has low service life, low gold and silver grade in the smelting product alloy, high gold content in the slag and low gold yield. Gold leaching with gold mud acid, , One step to obtain a new process of gold and silver alloy at the same time studied the amount of sulfuric acid, leaching time on the leaching rate of zinc. The test results show that using the new process not only can eliminate the harmful effects of zinc on the melting process, prolong the service life of the crucible, and can recover the zinc. When the amount of sulfuric acid is 15% ~ 17% of the theoretical amount, the leaching time is not less than 80min and the solid-liquid ratio is 1: 3, the leaching rate of zinc is ≮95%. Gold-bearing leachate smelting under appropriate conditions, slag gold can be reduced to about 40g / t, the gold yield of 998% or more.
