Ores are solid material from which a pure metal can be obtained. The process of removal of unwanted material from the ore is known as concentration or dressing or benefaction of ores. It involves several steps. The separation of required material ...

Copper Mining and Processing: Processing of Copper Ores ...

Although the processing costs are higher, ultimately more copper can be extracted. Since each mine site is unique in its mineral composition, concentration, and quantities, the most economical and profitable processing of ore must be determined by the mine planners.

Mineral deposit | Britannica.com

Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Ore – Official Minecraft Wiki

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. Note this can be increased greatly with fortune.
