in simple ores, the amenability of the composite to the recovery influenced by the gold minerals distribution, gold particle size, degree of oxidation and occurrence. sometimes, gold deposits are not exploited due to the mineral was not well understood and the process was not able to give high recoveries, or at least, expected recoveries.
the gold ore is then gathered up and taken to a mill for refinement. 2 placer deposits contain large pieces of gold ore nuggets and grains of gold that have been washed downstream from a lode deposit and that are usually mixed with sand or gravel.

jewelry: jewelry is the most common way gold reaches consumers, and has been a primary use for the metal in various cultures. because of its beautiful and durable properties, gold jewelry is an adornment that is both ethereal and revered. especially in india, adorning the body with gold is a way to attract wealth and blessings.

products made from iron ore. smelting is a heating process in which the iron ore is heated along with coke charcoal and limestone in a blast furnace. the heating process melts the iron contained in the mixture and eliminates much of the carbon that is contained. using variations of this process iron ore is also used as a base to derive pig iron, cast iron and steel.

refining gold. the final product can collect gold and platinum group metals. perhaps, small miners can considers this option when there are economical restrictions and the final product quality is not very important. the inquartation and parting process is based on the solubility between gold, silver and copper.
alloying gold with other metals changes the color of the finished products see illustration . an alloy of 75% gold, 16% silver and 9% copper yields yellow gold. white gold is an alloy of 75% gold, 4% silver, 4% copper and 17% palladium. other alloys yield pink, green, peach and even black-colored metals.
when gold dissolution is complete, the gold-bearing solution is separated from the solids. with ores of higher gold content greater than 20 grams of gold per tonne of ore , cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.
uses of gold in the united states: this pie chart shows how gold was used in the united states in 2017, not including gold bullion. the main uses were in jewelry (38%) and electronics (34%). the minting of official coins accounted for 22% of the gold used, and 6% was for other uses.
it is particularly appropriate for low grade gold and silver ore processing (e.g. less than 5 ppm gold) but its use is not restricted to such ores. there are many environmental hazards associated with this extraction method, largely due to the high acute toxicity of the cyanide compounds involved.
also, grinding the ore to an extremely fine particle size can liberate gold encapulsated in sulfides. sgs has very extensive experience with all the unit operations involved in the processing of refractory gold ores, and in selecting the optimum flowsheet for a
