The most costeffective process is to create adsorption of the dissolved gold and/or silver onto activated carbon, resulting in an easier solidsolid separation based on size. To achieve this the ore particles must typically be smaller than 100 µm while the carbon particles must be larger than 500 µm.

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 45 redstone dust, and lapis lazuli ore drops 49 lapis lazuli. Note this can be increased greatly with Fortune.

Vat Leaching of Finely Crushed Gold Ore. Previous Next It is more common if the flow of solution is continuous through a series of vats. If the solution enters either at the top or the bottom, but is withdrawn from the bottom, the system is known as downward percolation, which is the more common method if the batch method is used.

The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ''see'' the gold in the leaching process.

as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.

Mineral Deposit Value How to Calculate the Potential

Mineral Deposit Value How to Calculate the Potential

As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
