Tailings Characteristics and Handling
The tailings mass balance for production and neutralization, and the product
geotechnical characteristics will need to be confirmed to verify the assumption
used in the TSF preliminary feasibility design. These include the handling
requirements for transport and placement of the tailings, and potential changes in
characteristics and behavior over time and exposure to climatic conditions.
Tailings Geochemical Characteristics
Additional geochemical testing is needed to properly characterize the tailings
once the final tailings product and neutralization mass balance are defined and
representative samples in sufficient quantity are available for testing. Testing
includes interaction/compatibility of tailings seepage with the foundation soils.
