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 lead-zinc sulfide ore.

Calculate the Value of Silver by its Weight. This will calculate the value of a certain weight of silver in U.S. Dollars, British Pounds, and Euros. Note: Precious metals are typically weighed in troy ounces and pounds, which are slightly different than standard ounces and pounds.After primary jaw crushing to minus 5 inches, ore is fed to the single SAG mill (9' x 22', 1,500 kW motor) operating in closed circuit with cyclones. Throughput and power is increased by adding 5" diameter steel grinding balls. The Bond Work Index is reported to be 14 kWh/t.

The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries.yttrium zirconium niobium molybdenum technetium ruthenium rhodium palladium silver cadmium indium tin antimony tellurium iodine xenon ...

The gold and silver head grades for the two composites were determined by screened metallics tests conducted at 106 µm. The gold head grades obtained are 3.92 g/t Au for MET-1 …Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.
