<u>Answer: </u>

Metallic ores are produced by igneous and metamorphic processes.

<u>Explanation: </u>

  • Metallic ores are present in every type of rock and few varieties of soil. These get concentrated into "rich masses by igneous, metamorphic processes". Metals precipitate as sulphide minerals in a cooling body of magma.
  • Magmatic deposits occur when the "minerals settle to the bottom" and form layers. Metamorphic deposits rich in copper, cobalt, lead, zinc from hot solutions circulate through the rocks.
  • The solutions come from heated meteoric water. Constant changing pressures result in precipitation of sulphides or pure metal like gold, copper, silver.
  • This process is repeated again and again until the systems are filled with mineral deposits.
