Metal Recycling

Modern technology diversifies people’s lifestyle and also accelerates the generation of all kinds of scraps, for example, the electric and electronics are updated every 1-3 years. Among these scraps, WEEE/PCB, spent lead acid battery, nickel metal hydride battery, lithium-ion battery are of great value and have to be treated in a safe and economic manner.

Metalcess is a professional company offering metal extracting/ recovery/ recycling solution. We provide customer-tailored engineering process and service for medium and small-scale metal recycling projects. Whether standard or non-standard application, we are confident to offer the most optimal solution targeting stable performance, flexible and clean operation and environmental-friendly effects.

Metalcess provide PM recovery≥99.6%, TBRC mini-scale smelting system to recover precious metal and rare metal from anode slime,WEEE/PCB/IC,copper scrap and gold-silver refining ash/slag/residue.
Rotary Reverberatory Furnace Smelting

The furnace can be designed with effective working volume minimal 0.15m3, suitable for the recovery of anode slime, PM-containing smelting slag, lead refining dross and all kinds of dust. It can also treat secondary material like scrap copper, WEEE/PCB/IC and etc.

Slag/Dross Recovery

Slag/dross and leaching residue are produced from the process of metal extraction. The commonly-seen slag/dross/residue includes copper dross, lead dross, tin slag, zinc leaching residue, antimony/arsenic dross, cadmium residue/cake, sulfur residue/cake, vanadium slag, nickel slag, iron tailing and iron bearing red-mud waste.

Due to its low concentration, it may be not profitable to extract single metal, so it is usually landfilled. However, the increasing awareness of environment protection requires a safer and better treatment method. Comprehensive recovery of these slag/dross has been emphasized with greater attention.

Metalcess is a professional company offering metal extracting/ recovery/ recycling solutions. We have rich experience in slag treatment. We cater for smelting process to coordinate with clients’ existing operation, achieving safe and comprehensive slag recovery and high ROI.

Metal Distillation Separation

Metal distillation is the thermodynamics process using the difference of boiling points of metal alloy to separate them from each other. Usually, the metal of low boiling points is evaporated from the liquid alloy and later the vapor is condensed in a separate container. In a distillation system, by setting up condensing elements along the evaporation passage, the metal of high boiling point gets condensed before taking away by the vapor. Consequently, low boiling point metal are purified.

Distillation technology is applied for many industrial sectors to treat scrap/waste generated from industrial production and daily use household, especially favored by high purity product application.

Metalcess is a professional company offering metal distillation technology. Metalcess is specialized in treating waste acid with organics from chemical plant and pharmaceutical factory, lead-tin alloy, silver froth, crude zinc with lead and cadmium, hard zinc with aluminum and iron from hot galvanizing, waste acid with selenium and mercury from acid-making process, and soldering tin from waste electrical and electronic element, etc.
