Ores and Minerals
First ores are crushed and grinded and then gauge or matrix is removed from the powdered ore. This is called concentration of ores. Ores of highly, moderately, and low reactive metals are 1 st concentrated. This step is common for ores of all types of metals. It is carried out by various methods depending upon the nature of the ore.

Problem 15 Hard Difficulty. An assay is performed to determine the gold content in a supply of crushed ore. One method for pulling gold out of ore is to react it in a concentrated cyanide (CN") solution.
Gold Mine | Anno 1800 Wiki | Fandom
Gold mines produce gold ore from gold deposits in the mountains. It can be built in, where it requires a gold deposit, or in, where the building is called a "Deep Gold Mine" that requires both a gold deposit and heating. A New World Gold Mine takes 150 seconds to produce 1 ton of gold ore so the production rate is 0,4 tons of gold ore per minute. Productivity can be changed by adjusting ...
