Description: Tombstone, Arizona State Of Maine Mining Co .999 Pure Very Large Silver Crystal Extremely Rare. These items are part of my family estate who were in the mining industry in Tombstone Arizona since the 1890's. From the Bailey Escapule & Fred Libby Jr Collection. Included in this sale will be copies of some of the papers that were with these items including the flow sheet. This is an example from Bailey Escapule: In 1982, I, Bailey Escapule, poured these silver bars in Tombstone, Arizona, at the State of Maine Mine. The process used to recover the silver involved cyanide heap leaching. The ore was crushed and put on a pad, then sprinkled with cyanide for 30 days. During this time, the gold and silver dissolved into a solution called a pregnant solution. The solution was then run through a clarification filter and an oxygen-reducing vacuum chamber. Zinc powder was added to the pregnant solution to precipitate the gold and silver into concentrates. These concentrates were dried and smelted into a dore cone of silver, gold, and other metals. The dore metal was further smelted into an anode plate. The electrolytic process used anode and cathode plates to produce .999 silver crystals. These crystals were then poured into 1-ounce and 10-ounce bars. Each bar is individually stamped with the exact weight, purity, and the State Of Main Mining Company logo. I will be adding more info about the silver crystals from Fred Libby Jr and a little story from him on how they became a big part of his career and legacy of the State of Maine Mining Co.
