Solution

(A) Siderite-(II) Fe

  1. Iron carbonate (FeCO3), commonly known as siderite, is a common mineral that is iron ore.
  2. The mineral is typically found in hydrothermal metallic veins(as gangue, or waste rock). and thin layers with coal, clay, or shales (as sedimentary deposits)
  3. It looks like a collection of spheres, each of which is made up of thin, petal-like structures.

(B) Calamine-(IV) Zn

  1. Zinc is found in nature as zinc blende (ZnS), zinc calamine (ZnCO3), and zincite (ZnO).
  2. Fe2O4Zn is the molecular formula for calamine.
  3. It has a cellular or spongy appearance and dark grey or black in color

(C) Malachite-(I) Cu

  1. Malachite is a secondary copper carbonate hydroxide mineral with a black-green texture that can be bright or dark green in color (Cu2(CO3)(OH)2)
  2. In its own purest state, it comprises about 57.48%copper.
  3. Malachite is a byproduct of the weathering process that takes place on the surface of copper ore, however, due to its low natural resource and poor metallurgical recovery, it is typically not employed for copper extraction.

(D) Cryolite-(III) Al

  1. Cryolite is a mineral with the chemical formula Na3AlF6 and the chemical name sodium hexafluoroaluminate.
  2. The primary ore of aluminum is cryolite. These gangue-related earthy minerals are connected to the cryolite ores and are referred to as such.
  3. The cryolite has a glassy, whitish color.

Final answer:

(A) Siderite Fe
(B) Calamine Zn
(C) MalachiteICu
(D) Cryolite Al
