Electrolytic Gold Extraction
Apparently electrolytic extraction tended to aid the solution of undesirable substances. A porous pot was placed in a jar containing dilute sulphuric acid and a large sheet lead cathode. In the porous pot were placed a carbon anode, 100 grams of ore and 50 c.c. of a saturated sodium chloride solution and 5 grams of sodium chloride.
