SILVER ORES Even though certain silver bearing ores contain silver, none of them contain silver as their major constituent. A distinct ore might contain 0.085 percent silver, 0.5 percent lead, 0.5 percent copper, and 0.3 percent antimony and after flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony.

Apr 07, 2009 Canada remains one of the worlds leading mining countries and has become a centre of global mining finance and expertise. Description . Mining entails the extraction of ore, defined as rock from the earths crust containing valuable minerals. It may also include quarrying, or the digging of sand, gravel or aggregate for construction purposes.
Water is also added, which turns the ore into a slurry. We send this slurry to leaching tanks, where we add a weak cyanide solution to the slurry, which leaches gold and silver into the solution. This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution.
Dec 17, 2016 The ore is then crushed into finely ground tailings for processing with various chemicals and separating processes to extract the final product. In Canada on average for every tonne of copper extracted 99 tonnes of waste material (made up of soil, waste rock and the finely ground tailings) must also be removed.
