⛏ How Is Gold Collected?
Gold is collected through two main methods:
1. Placer Mining (Surface Gold)
Used in rivers, streams, and surface deposits
Common in historical gold rushes (e.g., California, Yukon)
Methods:
Panning – Manually washing gold from gravel
Sluicing – Using water channels to trap heavier gold
Dredging – Machines that scoop riverbeds
2. Hard Rock Mining (Underground or Open-Pit)
Most modern gold comes from this method
Gold is found inside rocks (quartz veins or ore)
Process:
Blasting or drilling rock
Crushing the ore
Extracting gold using chemicals like cyanide or mercury (in controlled industrial processes)
Purification through smelting or refining
🔬 New Technology in Gold Collection
Eco-friendly methods are being developed to reduce pollution.
Bio-mining uses bacteria to help extract gold.
Artificial intelligence helps locate new gold deposits.
Recycling of gold from electronics is also increasing.
💰 Interesting Facts
