Gold Mining Techniques

Gold mining techniques vary depending on the location and geology. The main methods include: 1. **Placer Mining**: This involves extracting gold from riverbeds or sediment by washing away dirt to find gold nuggets or flakes. 2. **Hard Rock Mining**: Involves digging deep into the earth to extract gold from ore deposits, often requiring blasting and heavy machinery. 3. **Heap Leaching**: A chemical process where crushed ore is treated with cyanide to dissolve and separate gold. 4. **Artisanal Mining**: Small-scale, often informal mining operations using basic methods, which can impact local environments and communities. Each technique has its own environmental and economic implications.
