How mercury is made material, history, used, processing
The Romans used mercury for a variety of purposes and gave it the name hydrargyrum, meaning liquid silver, from which the chemical symbol for mercury, Hg, is derived Demand for mercury greatly increased in 1557 with the development of a process that used mercury to extract silver from its ore1282009 in this episode: a little insight on mercury toxicity, as a response to all the comments on my other "experiments with the liquid metal mercury" videos MUSIC: VALVE SOFTWARE STILL ALIVE (from the video game "PORTAL")experiments with the liquid metal mercury IV YouTubeMercury is used in thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps and other devices, though concerns about the element's toxicity have led to mercury thermometers and sphygmomanometers being largely phased out in clinical environments in favor of alternatives such as Mercury (element) Wikipedia

Amalgamation: Using Mercury to capture fine gold, retort
Amalgamation has been used for thousands of years to recover small sized or fine gold When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam sluices, dry washers, and similar devices to aid capture of fine gold At the base of most of the old stamp mills was a plate amalgamator Amalgamation has been used for thousands of years to recover small sized or fine gold When clean gold comes into contact with mercury, the two substances mix to form a compound called amalgam sluices, dry washers, and similar devices to aid capture of fine gold At the base of most of the old stamp mills was a plate amalgamator Amalgamation: Using Mercury to capture fine gold, retort Coke first is ground in ball mills, All premises intended for operations involving the use of mercury must be equipped with general and local exhaust ventilation Sodium silicate is an alkaline substance, and can be harmful if it comes into contact with the skin or eyes or is ingestedChapter 82 Metal Processing and Metal Working Industry
