ENVIRONMENTAL SERVICES

Environmental services include:

  BIO-REMEDIATION OF CONTAMINATED WATER

        The technology is applicable for remediation of surface and groundwaters which have been contaminated with sulfates, nitrates, toxic metals (Cu, Hg, As, Cr, Cd, V, Se, Mo, etc.), radionuclides (U, Th, Cs, Sr, etc.) and organic compounds (oil products, formaldehyde). The technology utilizes naturally occurring micro-organisms for sulfate reduction under anaerobic conditions. Sulfates are reduced to insoluble carbonates and metallic compounds, radionuclides are transposed to a stable insoluble phase, and oil products are anaerobically oxidized by micro-organisms to produce CO₂ and H₂O.

WASTEWATER AND SLUDGE TREATMENT

       Wastewater and sludge treatment include: substitution/modification of process methods or chemicals; elimination of particular process steps; appropriate disposal of particular wastes; and recycling of particular materials and/or chemicals.

GROUNDWATER ANALYSIS

        MSRDI provides groundwater analysis (with certification) for identifying as well as quantifying toxic elements contaminating water-tables and aquifers.

MILL TAILINGS AND MINE WASTE TREATMENT FOR RESIDUAL METALS
RECOVERY

        MSRDI has always played a leading role in this particular area, even prior to the inception of the EPA and other regulatory agencies. Included are: heavy media upgrading of oil shale; preconcentration of minerals from low grade resources; recovery of fine and ultra-fine minerals; reprocessing of tailings and waste dumps; secondary metals recovery; resource recovery from municipal wastes; and silver and gold extraction from refractory ores.

METALS AND MINERALS RECYCLING

       MSRDI has also focused on marketing metals which are originally identified as being environmentally hazardous by collecting, assessing , and recycling such metals.
