Machine Operators

Mineral and stone processing plant operators run plant that crushes, grinds, saws and washes rock and ore and separates the useful minerals by flotation, filtration or magnets. They watch gauges and control panels; they do not work stone by hand like stonemasons.
Every department, for 12 months.
