Ore Characterization and Quality Control Aspects of Gold Cyanidation

because they present the problem of low-grade ores to the
metallurgist or mineral processing engineer. Quality control
operations are also significant in obtaining good products by flowing
the sequences of processes. In this study, the ore was characterized,
and quality control issues were discussed. Results showed that the
gold grade is 9.7 g/ton, the minerals are mainly silicates, and the pH
of the ore is high, which means that without pre-treatment, i.e.,
roasting, oxidation, etc., it can be cyanided directly. Therefore, the
CIL plant could recover more than 90% gold. In quality control of
the plant, from each unit at a different time, a representative sample
and an accumulative sample were collected and then subjected to
analysis like fineness and solid percentage, moisture, and conditions
of cyanidation. The results showed steady operation conditions for
each unit.
