For many others, however, the reserves are estimated to be good for only ~20 years: e.g., lead, chromium, gold, and silver. As reserves supplies decrease, prices tend to rise, leading to the opening of new mines or extraction technologies that may not have been practical to use when the prices to extract were too costly.

Lead. Lead occurs as galena (PbS), cerisite (PbCO 3), and anglesite (PbSO 4).Galena is the most common. Lead ores are usually roasted and then reduced in a blast furnace with coke. Purification is carried out by adding zinc, which removes silver (Parkes process), or by electrolysis in a solution of lead hexafluorosilicate and hexafluorosilicic acid (Betts process).

Placer deposits are formed by flowing water, e.g. streams or along coasts. As the water velocity slows down, e.g. at a point bar in a stream, minerals may, over time, settle out and accumulate in these regions. The California gold rush of 1849 began when someone discovered a placer deposit of gold draining from the Sierra Nevada mountains.

The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].
