Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores

A. Concentration or Benefaction of the Ore. This is a very important in metallurgy. The ore is obtained from the earth and usually contain dust, stone, quartz, feldspar and other foreign materials.These impurities are known as gangue or matrix. The process of separation of gangue from ore is known as concentration.
ENRICHMENT OF ORE OR CONCENTRATION OF ORE. Before extracting the metal from an ore, it is necessary to remove the impurities present in it. By removing these impurities we get a concentrated ore which contains a high percentage of metal in it.
↑ This refers to coal ore blocks spawned in ore veins and not as parts of fossils or mansion forges. ↑ Instead of multi-block veins, emerald ore is placed in scattered blocks. ↑ Nether quartz spawns equally in all parts of the Nether. ↑ Unlike most other ores, lapis lazuli's frequency peaks around layer 15, and slowly tapers off above
