In the process of non-ferrous metal smelting, silver slag treatment has always been a technical problem
for enterprises. The low processing efficiency, serious loss of precious metals, high risk of environmental
pollution and other pain points that exist in the traditional process are being fundamentally solved with
the in-depth application of intelligent technology. In this paper, we will analyze the silver slag processing
automation transformation of the six major technological breakthroughs, revealing the transformative
opportunities brought about by intelligent transformation for the industry.
Intelligent sorting system to achieve accurate purification
Intelligent sorting device based on multi-spectral imaging and X-ray sensing can analyze the parameters of silver
slag components in real time. Through the synergistic control of high-precision robotic arms and AI algorithms,
the processing system can complete the identification of slag components within 0.3 seconds, realizing
millimeter-level sorting of silver elements and other metal impurities. Compared with the traditional magnetic
separation - flotation process, the precious metal recovery rate increased by 27%, and the silver content of
the tailing slag was reduced to less than 0.03%.
Dynamic reaction control improves processing efficiency
The closed-loop intelligent control system automatically adjusts the process conditions of the reactor through
online monitoring of 18 key parameters such as pH, temperature, ion concentration, etc. The system is equipped
with a predictive maintenance module. The system is equipped with a predictive maintenance module, which
can warn of equipment abnormalities 24 hours in advance to ensure continuous production stability. The actual
application data shows that the reaction time is shortened by 40%, the consumption of chemicals is reduced
by 33%, and the daily processing capacity of a single line exceeds 50 tons.
Digital twin optimization process for the whole process
The virtual factory created by three-dimensional modeling technology can synchronously reproduce the operational
status of the production site. Process engineers through the digital twin platform, can be completed in the virtual
environment, process parameter tuning, equipment layout improvement and other simulation tests, the technical
reform cycle from the traditional mode of 3 months compressed to 72 hours. After a medium-sized smelting
enterprise applied the technology, the cost of silver slag treatment dropped by 1,200 yuan per ton.
Environmental monitoring network ensures compliant emissions
The distributed IOT sensing network covers the whole process of wastewater and waste gas treatment, tracking the
emission data of 21 types of pollutants in real time. The intelligent environmental protection control platform is
equipped with three functional modules: automatic warning, traceability analysis and emergency treatment, which
reduces the risk of environmental violations by 85%. The matching intelligent dosing system can automatically
adjust the treatment program according to the fluctuation of water quality, and the reuse rate of wastewater is
increased to 92%.
Energy efficiency management center reduces operating costs
The intelligent power distribution system with integrated energy monitoring and optimization algorithms can
dynamically adjust the operating power of equipment. The system analyzes multi-dimensional data such as
production load, energy price, equipment status, etc., and automatically generates the optimal power plan.
The application cases show that the comprehensive energy consumption is reduced by 18%, the peak
electricity load is cut by 25%, and the annual electricity cost is saved over 2 million yuan.
Quality Traceability System Enhances Product Value
The blockchain-enabled traceability system completely records the data of the silver slag treatment process,
forming a tamper-proof quality file. Each batch of recycled silver products comes with a digital certificate
containing 11 key information such as purification process and inspection report. The system increases the
product premium capacity by 15%, helping the enterprise to enter the supply chain of high-end electronic
materials.
At present, intelligent transformation is promoting the silver slag treatment process to the direction of precision,
cleanliness and high value. Intelligent processing system with self-adaptive ability can not only effectively respond
to the fluctuation of raw material composition, but also build up a new model of circular economy for the
enterprise. With the deep penetration of 5G + industrial Internet technology, in the next three years, the market
penetration rate of intelligent silver slag processing equipment is expected to exceed 60%, becoming the core
driving force of the industry to improve quality and efficiency.
For non-ferrous smelting enterprises, grasping the window period of intelligent transformation is not only about
environmental compliance and cost control, but also a strategic choice to reshape core competitiveness. By building
a closed-loop system of intelligent perception-autonomous decision-making-accurate implementation, the
traditional silver slag treatment process is completing its transformation and upgrading to modern green
manufacturing, opening up new paths for the sustainable development of the industry.
