中文摘要: 分别在20~70 ℃、硫化钠浓度20~80 g/L范围内对含锑难冶炼金矿碱性湿法脱锑过程中金的浸出动力学进行研究。结果表明:在该范围内碱性硫化钠浸出锑金矿过程中,金的表观活化能Ea=10.948 kJ/mol,表观活化能较小,表明在考察范围内,金浸出主要受反应物扩散过程控制;在碱性硫化钠浸金过程中,仅从表观速率来看该反应未达到平衡时,硫化钠在溶解金的反应中级数为3.07。
Abstract:Leaching kinetics of gold from refractory antimony-bearing gold ores with alkaline sulfide under the condition of 20~70 ℃ and sodium sulphide concentration of 20~80 g/L was studied. The results show that apparent activation energy for gold leaching with sodium sulfide is Ea=10.948 kJ/mol within the scope. Lower value of Ea shows that gold leaching is controlled by diffusion of reactants. During gold leaching with sodium sulfide, when leaching reaction does not reach equilibrium only from perspective of apparent rate, reaction series of sodium sulfide in gold dissolution is 3.07.
