Lode deposits of gold containing minerals are the result of volcanic activity, so minerals like quartz may appear near gold. Another type of gold ore is the result of cementing within hosts of sedimentary rocks after making its way down a river.
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth's crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions ...
Obtaining resources from ores is as simple as mining them (this is not the case for iron and gold ores, which must be smelted). Coal, diamond, emerald, and nether quartz ores drop 1 unit corresponding raw materials. Redstone ore drops 4-5 redstone dust, and lapis lazuli ore drops 4-8 lapis lazuli.

Quest ore is usually mined off special nodes, but can also drop off certain mobs in the same area. The ores cannot be smelted and are not "quest items" per se, so they can be traded or purchased off the AH. Mining bugs. Nodes have been known to respawn in rapid succession immediately after mining.
the California Gold Rush of 1848 and the following years. After gold ore is formed through hydrothermal deposition, it is near enough to the Earth's surface, that it can be mined for its monetary and aesthetic value. Common mining procedures of the California Gold Rush included placer mining, hydraulic mining, and lode mining. The promise of

Sep 21, 2010· Some of the byproducts of that degradation process, such as nitrates, may contaminate groundwater, but a bigger issue is that the use of cyanide allows mining companies to go after very low-grade ore.
waste called 'tailings,' the residue of an ore that remains after it has been milled and the desired metals have been extracted (e.g., with cyanide (gold) or sulfuric acid (copper)). If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then the mine project will generate a similar quantity of ...

This entire process is called "lode mining" or "hardrock mining". Millions of years passed after the rich mineral lodes were formed, during which time a large amount of weathering was caused by heat and cold, animals and vegetation, rain and wind, snow and ice, glaciers and their resulting runoffs, earthquakes, and ocean tidal changes ...
Even though gold and platinum ore (and bars) are of nearly equal sell value, 1 platinum coin is worth 100 gold coins. This is likely because platinum ore and bars were added after platinum coins, and also is a reflection to the real-world metals (in this case, platinum would be the higher rank).
Gold Mining - Abundance of ore# Gold is extremely rare. According to geological experience essentially all gold is found only in low concentrations in rocks. Gold is rarer even than platinum, although because of platinum's more even dispersion in the Earth's crust it is actually harder to find commercial deposits of platinum.
