Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).
been from ore first discovered by the Remans.3 At Rio Tinto, the Remans mined the upper, ox-idized, part of the ore and collected the copper-Iaden solutions produced by water slowly seep-ing down through the suIfide ore bodies. When the Moors conquered this part of Spain during the Middle Ages, the oxide ores had largely been exhausted.

the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water and initial flotation reagents to form slurry. The ore is then ground in rod and ball mills. The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semi-autogenous mills (steel balls are added to the ore).
When the grade of the chromite was low, mills were needed to concentrate the ore; miners often converted mills used for gold. During World War I and World War II, Oregon's contribution to the domestic production of chromite varied from one-fifth to one-quarter. The Blue Mountains provided most of the chromite from the state in the early years ...

In 1894, H.Y. Castner discovered that mercury could be used in the chlor-alkali process to produce chlorine and caustic soda. And during WWII, the Ruben-Mallory battery (mercury dry-cell battery) was invented and widely used. By the early 1900s, the main uses of mercury were in making scientific equipment, recovering gold and silver ...
4 thoughts on " History Of Mercury Use in Products and Processes " Randall January 15, 2013 at 10:44 pm. Mercury has been used through-out history in many interesting ways, sometimes with disastrous effect. Unfortunate the element is so fascinating to look and has some truly extraordinary uses.

For minerals with very low ore grades, fuel can be a significant factor in the cost of the final product. Rare earth elements, used in all manner of tech machines, including green ones, have rare properties but are much more abundant than gold. However, the physical chemistry of rare earths makes them difficult and energy-intensive to refine.
