Restriction on the dissolution of Ag in Sb-Au alloy chlorination leaching process
It is difficult to completely recycle Ag which dissolved in the chloride solution.In this paper,when treating with Sb-Au alloy by chlorination leaching ,four leaching mediums such as the lower concentration medium of HCI,HCI-NaCl medium,HCl-H2SO4 medium and the higher concentration medium of HCI were studied to restrict the dissolution of Ag into chloride solution.Results showed that the acidity,the leaching potential and the total concentration of Cl- in the medium were key factors.Treating with the alloy in HCl-H2SO4 medium,while the condition was controlled as:HCI 5mol/L,H2sO4 1mol/L,L/S 7:1,potential 100mv.The leaching rate of Sb was 89.1%,the residue rate was 5.5%,and about 82.5%of Ag in raw alloy remained in the residue.
如何抑制银在从锡-金合金中提取时被氯化.
想要从熔解的氯化物中充分回收银时很难办到的.所以正如本页所提到的,当采用氯化过滤处理锡-金合金时,通常有四种方法被用来研究如何抑制银被氯化：低浓度盐酸法、盐酸-氯化钠法、氢硫酸法和高浓度盐酸法.结果显示,酸度、电势和氯离子的浓度是解决问题的关键.使用氢硫酸法处理时,使参与反应的物质浓度如下：HCI 5mol/L,H2SO4 1mol/L,L/S 7：1,电势为 100mV.那么锡的滤出率为 89.1%,渣中剩余5.5%,并且约有82.5%的银会留在初渣当中.
