    MINING AND PROCESSING : Lead is known to naturally occur in free form in nature, but is generally obtained from the ores galena(PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4). It is never considered to be a rare element even though it makes up only about % of the earth's crust since it is easily mined and refined.

    As mentioned above, the gold grains in many epithermal deposits are very minute, requiring a cyanide process for extraction, as well as the complex methods used to extract gold from a silica ore. Recently the Japanese government has tried to find more epithermal gold deposits. As a result, the Hishikari mine was discovered in 1981. This has an estimated total gold of 250 tonnes with an average ...

    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.
