Abstract

Abstract:

Rational allocation of leaching rates is significant for the organization of leaching process production. Generally, each leaching rate is given by engineers with the help of their experiences, which makes the supervision of leaching process production with a large extent of fuzziness and randomness, and it does not guarantee that the adjusted total leaching rate is the maximum. In order to determine the optimal leaching rate of gold hydrometallurgy process, an optimization model is established with maximizing the total leaching rate of hydrometallurgy process as the goal. And the second-order oscillating particle swarm algorithm is applied to solve the model. Finally, an experimental research demonstrates the effectiveness of the established model and algorithm.

Key words: gold hydrometallurgy, cyanidation leaching, leaching rate, optimization model, particle swarm algorithm

摘要：

各浸出率的合理分配对组织金矿湿法冶金浸出过程生产具有重要作用,当前各浸出率通常由精炼厂氰化车间工程师凭人工经验给出,导致对浸出过程生产的指导具有很大的模糊性与随意性,不能保证调整后的总浸出率最大。为优化确定金矿湿法冶金各浸出率,建立以总浸出率最大为目标的优化模型,并将二阶振荡粒子群算法用于模型的求解。最后通过实验研究验证了模型和算法的有效性。
