金电解精炼残极率影响因素与系统性控制策略研究

Study on Influencing Factors and Systematic Control Strategies of Residual Electrode Rate in Gold Electrolysis Refining Process

摘要

残极率是衡量金电解精炼过程经济效益与技术水平的综合性关键指标。本文系统剖析了影响残极率的三大核心因素：阳极板自身质量（化学成分、物理结构）、电解工艺条件（电流密度、电解液体系、周期）及生产操作管理。研究指出，高银含量导致的阳极钝化是残极率升高的首要原因。在此基础上，本文提出了“源头控制-过程优化-操作规范-管理闭环”的四位一体系统性控制策略。通过采用绿色节能技术、智能化管控手段及全流程数据驱动，可实现残极率的精准控制与生产效能的全面提升，对推动黄金冶炼行业的高质量与可持续发展具有重要指导意义。

Abstract

The residual anode rate is a comprehensive key indicator for measuring the economic efficiency and technical level of the gold electrorefining process. This paper systematically analyzes three core factors affecting the residual anode rate: the inherent quality of the anode plate (chemical composition, physical structure), electrolysis process conditions (current density, electrolyte system, cycle), and production operation management. The study identifies anode passivation caused by high silver content as the primary reason for the increase in the residual anode rate. Building on this, the paper proposes a systematic “source control-process optimization-operation standardization-management closed-loop” control strategy. By adopting green and energy-saving technologies, intelligent management methods, and full-process data-driven approaches, precise control of the residual anode rate and comprehensive improvement of production efficiency can be achieved. This holds significant guiding importance for promoting the high-quality and sustainable development of the gold smelting industry.
