produced for electrowinning which is followed by smelting to create doré bars. Doré is a semi-pure alloy of gold and silver. Gold by nature is very dense (19.3x denser than water and 7.3x denser than quartz) and malleable, causing it to grind slowly. These properties cause gold particles to preferentially report to the cyclone

The La Demajagua gold/silver deposit incorporates the Delita deposit which was discovered around 1900 but received only cursory attention until the 1920s when a North American company acquired the concession. Production was minimal until after World War ll. In the period 1947 – 1950, approximately 60,000 t of ore were mined underground.

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.

You need quartz with at least 10 parts per million silver in order to smelt it using pre-modern techniques. This number was derived by comparing silver yields from smelting with silver concentrations determined by x-ray fluorescence and atomic adsorption (Enderlin, 1993; Helm, 2000). Samples came from the Silverado Mine and its environs.

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.
