  1. Aboutus Ambiotek SpA, is a spin off from Universidad de Santiago de Chile, that develops and offers environmental solutions for the mining industry. Ambiotek’s vision is to become a world class supplier for a more sustainable mining industry.

  2. What do we do? • Ambiotek SpA supports mining industry in regulatory compliance and enhancement of its environmental liabilities giving added value to solid and liquid residues. • Our offer is based on over 10 years of applied research with mining companies and our network of national and international partners.

  3. OUR OFFER • Chemical & mechanical stabilization of mine storage facilities and surrounding areas • Phytomining of mine storage facilities and surrounding areas • Treatment of wastewater and acid water derived from miming activities

  4. 1. Chemical and mechanical stabilization of mine storage facilities and soil We prevent dispersion of dust and particulate material by using native plants and microorganisms. Higher effectiveness at lower investment and operational costs Up to 30% potential reduction of particulate matter due to air erosion Potential metals recovery Potential power generation More aesthetically attractive solution Technologytested in Salar de la India (Chile) (Project FONDEF D06I1097), and implemented in Talabre (Chile) world'slargesttailingdam.

  5. 1. Chemical and mechanical stabilization of tailings and mine soilsEffectiveness ResultsfromPilotPlant - Project Fondef D06I1097: (Parameters evaluated after 13 months of implementation)

  6. 1. Chemical and mechanical stabilization of tailings and mine soilsEstimative Costs The process has three steps: • Diagnosis cost: MCh$ 5,000 • Implementation cost per hectare: between Mch$ 30,000 to MCh$ 37,000 (*) (*) Cost fluctuates according to the specific conditions of the site and the tailings

  7. 1. Chemical and mechanical stabilization of tailings and mine soilsAesthetic and Environmental Benefit

  8. 1. Chemical and mechanical stabilization of tailings and mine soilsCopper recovery • Tailing dams have about 26 000 tons of potentially extractable copper • Sand of tailings: 0.2 to 0.4 % Cu • Water of tailings: up to 2 ppm Cu at pH 7.5 • Sediments: 0.4 % Cu

  9. 1. Chemical and mechanical stabilization of tailings and mine soilsPhytomining 1. Growth of metal hyperaccumulator/accumulator plant species 2. Biomass harvest 3. Burning of biomass to recover the metal.

  10. 1. Chemical and mechanical stabilization of tailings and mine soilsRecovery potential & Operational Cost • Theoretical yields based on data from empirical copper accumulation: - Grass (Polypogon australis): 7.0 tons dry weight/ha/year. Average copper accumulation: 4.6 kg Cu/ha - Woody (Atriplex deserticola): 20 tons dry weight/ha/year. Average copper accumulation: 26 kg Cu/ha - Phragmites australis: 52.7 tons dry weight/ha/year. Average copper accumulation: Cu 15.8 kg/ha • Referential operational cost: 3 MUSD/ha.

  11. 2. Mining wastewater treatment, and acid water treatment

  12. Biological systems (plants and microorganisms) to the depletion of copper and sulfate, and improvement of pH and electrical conductivity. The offer includes diagnosis, conceptual and detailed engineering, implementation and monitoring of the solution.. • Technology being tested in a semi-industrial scale in Codelco Chuquicamata. 2. Mining wastewater treatment, and acid water treatment

  13. 3. Biofilter for depletion and/or recovery of metals • Development of adsorbent matrixes made off native brown algae biomass for the recovery and/or depletion of copper, arsenic and boron. • Technology at experimental stage.

  14. Partnerships and collaborations
