Unleash Potential | Liming Heavy Industry's Lithium-Containing Waste Resource Recovery and Utilization Solution

Amid the rapid development of the global new energy industry, lithium, known as "white petroleum", has become a core resource supporting strategic fields such as power batteries and energy storage equipment. However, the mining of primary lithium ore is facing three major challenges: limited resource reserves, high environmental costs, and rising mining costs, leading to an increasingly prominent contradiction between supply and demand.

Against this backdrop, lithium-containing waste, known as "urban mines", has become the key to breaking the deadlock, thanks to its advantages of concentrated resources, low recycling costs, and significant environmental benefits.

Four Recycling Directions of Lithium-Containing Waste

1. Overhaul Slag

It comes from waste cathode carbon blocks generated during the overhaul of electrolytic aluminum cells. Recycling it can solve the problem of hazardous waste disposal and recover components such as fluorine and carbon.

2. Waste Electrolyte

It is the waste electrolyte replaced during electrolytic aluminum production, with a lithium content of 1%-3%. Recycling it can reduce the risk of fluoride solid waste accumulation.

3. Carbon Slag

It is the residue produced in the electrolytic aluminum process, entraining electrolyte with a lithium content of 0.5%-1.5%. After treatment, components such as lithium and metallic aluminum can be recovered.

4. Lithium-Containing Waste Glass

It comes from the leftover materials of consumer electronics screens (e.g., mobile phones) and lithium-containing glass components disassembled from scrapped equipment, with a lithium oxide content of 1%-4%.

Recycling Process Flow of Lithium-Containing Waste

Solid wastes with complex components such as aluminum electrolyte, carbon slag, overhaul slag and lithium-containing waste glass contain high-value lithium resources. Efficient grinding is an important link in resource recycling.

High-Performance Equipment Demonstrates Solution Strength

Liming Heavy Industry has focused on the grinding field for nearly 40 years and launched core equipment solutions including the MTW European trapezium grinding mill and LM vertical roller mill. With excellent material adaptability, operational stability and precise particle size control capability, it efficiently processes diverse lithium-containing solid wastes. This lays a solid raw material foundation for the subsequent efficient separation and extraction of key valuable elements such as lithium, and unlocks the potential of "urban mines" through high-performance equipment and one-stop services.

LM Vertical Roller Mill

LM vertical roller mill is a large-scale, high-efficiency and energy-saving grinding product developed by Liming Heavy Industry with great concentration, integrating nearly 40 years of R&D and manufacturing experience. It integrates drying, grinding, powder selection and conveying functions in one, and owns a number of independent patent technologies and intellectual property rights. Its main technical and economic indicators have reached the international advanced level.

MTW European Trapezium Grinding Mill

MTW European Trapezium Grinding Mill is a patented product of Liming Heavy Industry, with a number of independent patent technologies and intellectual property rights. It features high grinding efficiency and large output, and serves as an upgraded replacement for traditional Raymond mills and pendulum mills. It is widely used in fields such as power plant desulfurization, large-scale non-metallic mineral powder production, building materials, and chemical engineering.

One-Stop EPC General Contracting Service
