RECOVERY OF SILVER, GOLD, AND LEAD FROM A COMPLEX SULFIDE ORE USING FERRIC CHLORIDE, THIOUREA, AND BRINE LEACH SOLUTIONS By R. G. Sandberg 1 and J. L. Huiatt 2 ABSTRACT The Bureau of Mines investigated a hydrometallurgical procedure to re cover gold, silver, and byproduct lead from a complex leadzinc sulfide ore.
Lead processing Lead processing Mining and concentrating: Once the ore is removed from veins (narrow channels) or lodes (roughly spherical deposits) in the Earth, usually at depths of about 60 metres, the ore is treated at concentrating mills. Here the ore is finely crushed, sometimes to particle diameters of less than millimetre ( inch), and then treated by one of several mineral ...

Plants for the production of lead are generally referred to as lead lead production begins with lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.
It sounds absurd, but our resident alchemist, Mikey B got it to work. The gold that we got this way looked a bit black and bitty, but it was definitely gold. I don''t know how efficient the process was, but we probably got a couple of grams of gold from several large sacks of our goldbearing rock.
The refiner places the ore in clay pots, heats the vessels in a furnace and pumps chlorine gas into each pot. After cooking for a few hours, the refiner retrieves the pots and skims off the molten chlorides, leaving behind gold with a purity of to percent. The Miller process replaced the Wohlwill process for most of the industrial ...
