Barite or Baryte is a mineral consisting of Barium sulfate and is generally white or colorless. The baryte group consists of baryte, celestine, anglesite and anhydrite. Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore. It is used in the manufacture of paints and paper. Although Barite contains a ‘heavy’ metal, Barium, it is not considered to be a toxic chemical because of its extreme insolubility.
Malachite is a Copper Carbonate mineral that often forms botryoidal, fibrous or stalagmitic masses. It is often the result of the weathering of Copper Ores and is commonly found with Azurite, Goethite and Calcite. It is typically associated with Copper deposits including Limestone which is the source of the Carbonate. Malachite is found in many regions world wide and is usually shaded green in color.
