Rusredmet specializes in solvent extraction, a key process for the efficient recovery, concentration, and purification of valuable metals. This continuous, high-throughput method operates at ambient temperature and atmospheric pressure, minimizing energy and reagent use.

Benefits of Solvent Extraction:

Precise separation of metals with similar properties, including REEs, platinum-group metals, zirconium, hafnium, tantalum, and niobium;
Production of high-purity metals and compounds (99–99.995%);
Recovery from polymetallic ores, concentrates, and low-grade raw materials;
Environmentally responsible closed-loop processing with minimal wastewater and emissions;
Reduced capital and operating costs.

Our Capabilities:
R&D of new extraction processes;
Design of industrial and pilot-scale horizontal mixer-settlers, pulsed columns, and columns with mesh trays or structured packing;
Laboratory-scale multistage continuous extraction units;
Pilot testing and process optimization to determine mass transfer and phase separation parameters.

We design and manufacture two main categories of industrial solvent extraction equipment:

1. Flow-contact extraction columns
Energy-free column systems—tray columns and packed columns—where phase contact is achieved through counter-current flow.

2. Energy-driven extraction systems
Including:
Horizontal box-type mixer-settlers with mechanical agitation
Pulsed columns with mesh trays or packing
Air-agitated columns with mesh trays or packing

Our horizontal mixer-settlers offer working volumes up to 12 m³ and capacities up to 40 m³/h (total phase throughput). Column units are available with diameters up to 2,500 mm, heights up to 15,000 mm, and capacities up to 60 m³/h. Equipment is manufactured from polypropylene with a metal reinforced shell, ensuring durability and chemical resistance.

All extraction equipment is engineered to order, fully tailored to the specific process and operational parameters of each client.
