Silver occurs as native metal, but is usually found combined with sulfur. About two-thirds of the world silver reserves and resources are contained in copper, lead, and zinc deposits. Ores in which silver or gold is the main component account for the remaining one-third of total world reserves and resources. The chief silver minerals found in
Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves ...
The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9%.

So to make a 50ml of 10ppm silver solution, we will require 0.05ml of silver concentrate 10000ppm. We will need to further dilute the 0.05ml of silver concentrate 10000ppm in 49.95ml of distilled water to make 50ml of 10ppm silver solution. 0.05ml is equivalent to 1 drop of silver concentrate. And for reference, 1ml is equivalent to 0.03 fl. oz.
The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
In mining, the ore is extracted by drilling or blasting and then crushed and ground. The ore is then treated using extractive metallurgy. The Froth flotation process separates the Lead and other minerals from the waste rock (tailings) to form a concentrate. The concentrate, which can range from 50% to 60% Lead, is dried and then treated using ...
The zinc concentrate is actually the tails from this bulk separation step. The flotation tailing is the zinc concentrate. If the silver is associated with the galena, the silver reports to the lead concentrate. While pyrite is fairly easy to depress with lime, pyrrhotite is more difficult to depress.
