Geology Of Hard Rock Gold Deposits

Plate Tectonics, provides a basis for understanding the process of mineralization and ore deposits, including gold. According to this relatively new theory, the lithosphere, which is rigid and forms the outermost shell of the earth, is broken up into 8 major plates and several minor ones (refer to Figure 4). These plates contain both the ocean floors and continental lithosphere. When these

Hard rock ores form the basis of the majority of commercial gold recovery operations today, and are mined using open pit or sub surface mining techniques. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low grade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and

ROCK CRUSHING METHOD AND SEPARATING GOLD FROM ORES

Gold ore separation uses comminution techniques to break down the excavated rock, but the material hardly looks like a lustrous yellow orange metal. In order to properly free this rich element from the rock, the crushing stage has to be followed by a chemically active stage, such as the cyanidation process or the carbon in pulp release method. These reagents chemically separate the gold from
