Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages circulating meteoric fluids may interact with the magmatic
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.
As in certain ore deposit types the gold in low sulfidation epithermal fluids is being carried as a fire complex with sulfur. Earlier on greenstone shear zone hosted gold where we covered various ways to drop gold from a fire complex solution. I won t go through this again in detail but one of the key ways was to break the gold sulfur bond

Mesothermal gold deposits form half way up through the rise of the melt from the deep crust to the surface usually at a depth of less than 10 km but greater than 1 km. temperatures at these depths are generally somewhere between 450 degrees and 250 degrees Celsius. The term mesothermal veins is really a sack term referring simply to the depth formation. It pays little attention to the origin
Mining is a skill that allows players to obtain ores and gems from rocks. With ores a player can then either smelt bars and make equipment using the Smithing skill or sell them for profit. Mining is one of the most popular skills in RuneScape as many players try to earn a profit from the skill. On the map mining areas are identified with a regular pickaxe icon and the mining shop with a gold
Oct 29 2014 · The ore-forming fluids are thought to come from intruded granites or the dehydration of the rocks themselves as they are being metamorphosed. These sulphur-bearing fluids redistribute the gold which is not very compatible with other elements along shear zones toward the surface.

The definition of an ore is therefore technology dependent. If a technology is developed to extract aluminum from clays at an economically viable cost at a later date these could also be included among the ores of aluminum. Ore Deposit Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit.
MiningMiningUnderground mining When any ore body lies a considerable distance below the surface the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive and underground techniques must be considered. Counting against underground mining are the costs which for each ton of material mined are much higher underground than on the
