Liming Heavy Industry MTW European Trapezium Mill Achieves A Win-win Situation

Recycling Value of Copper Anode Slime

Electrolytic copper anode slime, as the insoluble residue formed during electrolytic refining, is rich in rare and precious metals such as gold, silver, selenium, and tellurium. It serves not only as a secondary resource of high economic value but also as a strategic reserve to alleviate the pressure of non-renewable mineral resource depletion. With the surging global demand for resource recycling, solid waste recycling enterprises are focusing on the in-depth development of copper anode slime. Through advanced processes, they achieve efficient extraction of precious metals, driving the industry's transformation toward the "urban mine" resource recycling model.

Electrolytic Copper Anode Slime Precious Metal Recovery Production Line

Liming Heavy Industry has focused on the resource recycling track of copper anode slime. Through an innovative multi-stage grinding system and precise classification process, it grinds the processed copper anode slime into powder, improving the reaction activity and recovery rate of valuable metals in subsequent leaching, smelting, and other processes. This establishes a full-process solution for the high-value recovery of precious metals from copper anode slime.

Electrolytic Copper Anode Slime Powder Production Line by Liming Heavy Industry

Liming Heavy Industry has established a full-chain integrated service system for its copper anode slime powder production line. From precise chemical analysis of raw material composition and customized solution design to basic construction guidance, equipment installation & debugging, and technical training, a team of professional engineers is deeply involved throughout the process to ensure rapid project commissioning. The production line is deeply integrated with the user's on-site conditions. Through modular design and an intelligent control system, it achieves collaborative material processing and multi-metal cascading recovery, transforming the traditional approach of "turning hazards into safety" into "turning hazards into treasures"—realizing the integration of comprehensive solid waste management and reuse.

Customer Testimonial

Process Flow of Copper Anode Slime Powder Production Project

The process flow of the copper anode slime powder production project centers on efficient grinding and resource utilization. First, coarse particle impurities in the raw materials are removed through screening. During the drying process, precious metal-containing dust is generated and recovered by a pulse bag dust collector. Inside the grinder, the roller pressure is adjusted via hydraulic loading, and a built-in high-efficiency powder separator realizes cyclic re-grinding of unqualified coarse powder. The ground material is collected as finished product by a pulse bag dust collector.

The core advantages of MTW European trapezium mill

01 Exquisite technology and mature craftsmanship

After several generations of innovation, MTW European trapezium mill has reached a state of mature stability, which is widely applicable to various materials, demonstrating extensive adaptability and stability.

02 Precise fineness and excellent quality

Equipped with a new hanging cage type powder separator, integrated with frequency conversion control technology, the fineness of finished products can be freely adjusted and precisely controlled.

03 Green energy-saving and environmental protection priority

The advanced dust removal design complements the powder separation system, effectively curbing dust emissions during material grinding, perfectly aligning with the era concept of green development and contributing to environmental protection.

04 Safety first and explosion-proof guarantee

The entire production line is carefully equipped with explosion relief devices, and multiple safety explosion-proof measures are interlocked, featuring superior safety performance. Oxygen content detection points are set at key positions such as the mill inlet, outlet, and dust collector outlet, and nitrogen explosion-proof fire extinguishing devices are equipped to comprehensively safeguard production safety, effectively avoiding the risk of material self-ignition or explosion.

05 Simple maintenance and cost reduction

Using thin oil lubrication technology, the oil change cycle is long, and maintenance costs are significantly reduced. Meanwhile, by optimizing the grinding material process flow, resource waste is reduced, and operating costs are effectively controlled, adding more profit space to your grinding processing business.

Against the strategic backdrop of global efforts to promote green development and circular economy, solid waste recycling technologies such as copper anode slime have formed a demonstration effect in solid waste resource utilization projects, effectively connecting the industrial closed-loop of industrial solid waste regeneration and raw material value release. In multiple dimensions including efficient energy utilization and environmentally friendly production processes, Liming Heavy Industry has built a regeneration bridge from industrial solid waste to rare and precious metals with a series of practical achievements.
