The selection of elements as pathfinders for mobile form determination was based on data regarding ore mineral associations in gold ore occurrences located within study areas [14,15], and on the data about the elements most often associated with gold in the Baltic Shield [22,23]. Thus, mobile forms of gold and pathfinders, such as As, Ag, Cu, Ni, Zn, Pb, Te, Se, Mo, Bi, and Sb, were identified

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Arsenic Ores natural mineral formations that contain arsenic in quantities sufficient to make feasible extraction of the element and its compounds. More than 120 arsenicbearing minerals are known, the most common of which include arsenopyrite, FeAsS, containing 46 percent As loellingite (leucopyrite), FeAs2 (72.8 percent) realgar, AsS (70.1 percent

Cyanide is used to separate gold from ore. In its pure form, cyanide has no color and smells like bitter almonds. It may lose this smell when it combines with other chemicals. It can be used in powder, liquid, or gas forms. Cyanide is deadly when swallowed. An amount the size of a grain of rice is enough to kill a person.
