Industry & Occupation
Classification
Summary
Placer mining operators extract, transport, and sort sand and gravel resources to supply them as construction materials.
Description
Placer mining operators work in riverbeds, mountain quarries, and sea areas to extract placer minerals (sand and gravel). They operate heavy machinery (dump trucks, wheel loaders, dredgers, etc.) for excavation and dredging, and perform sorting and washing using belt conveyors and vibrating screens. The extracted resources are shipped as construction materials and various industrial raw materials. At work sites, they consider safety management and environmental protection, implementing measures to prevent sediment outflow and site restoration after work. They may also handle machine inspections and maintenance, troubleshooting, and verification of survey data. It is physically demanding heavy labor outdoors, requiring protective gear for dust and noise control.
Future Outlook
Stable job demand is expected due to sustained infrastructure development needs, but operators will need to upskill as automation and mechanization advance. With strengthening environmental regulations, environmentally friendly extraction techniques and recycling utilization may expand.
