What is shown in Dr. Pantoja's sketch is (or was) a common way to produce chlorine. The salt (sodium chloride) separates under electrolysis producing chlorine from the positive anode (graphite rod) and a sodium-mercury amalgam (Na(Hg)) from the cathode (mercury)
The  Na(Hg), is called activated mercury and it is considered superior to plain mercury because it holds together better and less is lost and often is reused.


However it is estimated that some 70 to 100 million persons are active in artisanal gold mining around the world including some 15 - 20  million women and children.  This board is located in British Columbia Canada where the use of such produces are banned and in general any discussion on the use of mercury is discouraged.

Millions of dollars have been spent in monitoring studies and bewailing the "horrid toxic effects" but only the very few have tried to produce solutions that work for the miners on the ground.
Most of the countries that have populations of artisanal gold mining have laws banning the use of mercury and cyanide but some 99% still obtain and use both.

All the best in your endeavors and be safe.

Hi.Crew cut good read.Too bad we cannot get it across to all the folks in Canada that still use mercury.It is death.Slow and painfull.Thousands of canadians have died or will die from polluted ground water and poison fish.It does not go away it follows the food chain.Bear eats poison fish hunter kills bear and eats poisoned bear hunter dies and is put in the ground full of mercury.And the cycle goes round and round,it never goes away.It should be banned period.Mcbain.
