DOM-TEC® TECHNOLOGY
How it works?
DOM-TEC® technology electrolytically extracts elements from solutions in a process not dissimilar to dialysis for cleansing of waste products in the human body. The unique system utilizes electro ionic membranes as a selective filter to preferentially remove and concentrate metals from solutions. The process has applications for cleaning effluents and recovery of metals from solutions for a wide range of elements and spectrum of concentration. Specific uses are for recovery of elements such as copper and precious metals in pregnant leach solutions that would conventionally be treated by SX/EW and other traditional extractive technologies. DOM-TEC® process does not require chemical or fossil additives and operates at room temperature.
This technology implies a paradigm shift in the mining industry, since it processes solutions at room temperature, without acid mist, without chemical or fossil additives, with variable flows and concentrations in an economically and environmentally sustainable way.
Types of liquors to be treated:
- Concentrations from 3 to 100 g/L.
- pH 1-13.
- Polluting elements (Fe, Cl, Bi, Sb, As, etc.).
- Inorganics and organics.
- Metals recovery (Cu, Fe, Sb, Zn, Au, Ag, etc.).
DOM-TEC® TECHNOLOGY ADVANTAGES
Environmental characteristics
- No acid mist produced.
- No chemical or fossil additives needed.
- Room temperature operation.
- Leaching agent recovery.
- Energy efficient (compatible with NCRE). Continued or Batch operation.
- Sustainable technology and environmentally friendly.
Low capital expenditure (CAPEX)
- “Turnkey Plant”. Modular and scalable design. Easy installation.
- Reduced required space (25% of a standard SX/EW plant).
Low operational and maintenance expenditures (OPEX)
- Corrosion resistant hardware (brine, acids and alkalis).
- Reduced EW times.
- Reduced work force.
- Optional cathodes harvests (Cu) in the same equipment.
- SX/EW processes in one step (reactive electro-dyalisis).
- Processes variable pH, concentrations and fluxes solutions.
- Polluting elements of solutions (As, Bi, Sb and others) do not interfere EW process.
- Modular and scalable.
- High purity Cu cathodes production (same quality as SX/EW process)
Main applications of DOM-TEC® technology
