There are a few common sense precautions which you must follow when working with Mercury. These include: Ø When working with Mercury always use latex gloves, they are cheap and provide good protection.. Ø Always store Mercury in tightly closed containers (unbreakable is better, and not ones made of Aluminum).. Ø Always put a layer of water on top of the Mercury unless it is charged Mercury.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer m
