Difference between limestone and manganese...... Geography
  • 1 answers

Meghna Thapar 5 years, 9 months ago

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. However, manganese is concentrated in various manganese rocks of sedimentary and hydrothermal-sedimentary genesis consisting predominantly (> 50%) of manganese minerals (Mn content—15–20% and greater); commonly this term is used in the literature as a synonym for manganese ore.
