What are three major types of of processes for extracting gold in png
Answers
GPT 3.5
1. Open-pit mining: This method involves creating a large open pit to access the gold ore, which is then extracted using heavy machinery and explosives. This process is commonly used in PNG due to the relatively shallow depth of gold deposits in the region.
2. Alluvial mining: Alluvial mining involves the extraction of gold from rivers and streams, where the gold has been deposited by water action. Miners use simple tools such as pans, sluice boxes, and dredges to extract the gold from the sediment.
3. Underground mining: Underground mining involves accessing the gold deposit through tunnels and shafts dug into the earth. This method is more costly and complex compared to open-pit mining but may be necessary for deeper deposits. Underground mining is less common in PNG due to the challenges of operating in remote locations with limited infrastructure.
