Its production of anode mud is expected to reach 800,000 tons per year to be used in gold and silver purification process.
Results from both tests indicate that the anode mud concentrate contains encouraging gold, silver and platinum group metal (PGM) grades.
In addition to the anode mud, the R&D laboratory which conducted the tests recovered a small amount of filter residue from the electrolytic solutions.
Pavlich continued, "Although the quantitative AA results of the filter residues were extremely encouraging, we remain cautious about extending the analytic results from that small amount of material to the anode mud.
This anode mud has been subsequently examined using both atomic absorption (AA) and Scanning Electron Microscope (SEM) techniques.
Pavlich concluded, "While we recognize that this approach represents a cumbersome assay procedure, we are pleased that the anode mud is, essentially, a saleable product.
