Refining Gold | HowStuffWorks

­The final stage of gold production -refining-involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals.

Marine gravimetry came to existence as a standard gravimetric technique some 50 years ago, even though the first attempts were made even earlier, in the 1920s and 1930s, on board submarines (Vening-Meinesz, 1932).It was clear from the beginning that marine measurements could not compete with land measurements in terms of precision. At sea, the gravimeter is subjected to the accelerations of

Gravimetry and Gravity gradiometry is a field of science which supposedly measures the strength of the earth's gravitational field. In these discussions Gravimetry is often used as evidence that the gravitational field of the earth varies with latitude and by location....

Gravimetric analysis Wikipedia

Gravimetric analysis Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle behind this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the

The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon....
