6 Ways to Identify Silver Ore - Something Borrowed

2021-7-23  Nowadays, people extract silver using a floating flotation process. It was discovered in the 20t century, and it involves placing ore in a bath. More so, air bubbles pass through the mixture and help transfer the silver to the top section of the flotation bath. Then, the silver-rich froth undergoes skimming and smelting for separation procedures.
