Abstract:

The Marvel Loch Operations (MLO) plant was treating ores from up to six MLO sources and in
addition needed to blend externally sourced ores with its own ores. This presented a metallurgical
accounting dilemma, which was subsequently addressed by the design, implementation and
testing of an automatic sampling system.
The MLO automatic sampler was well designed and has been the subject of previous internal and
external reviews. The sampling action is fully automated and the unit is essentially self cleaning
particularly when sampling primary ores. The purpose of this paper is to document the rationale
behind the design, the specific details of the sampling station, its use for ore purchase purposes
and an assessment of the sampling system to meet the needs of the operator.
