Ores And Minerals #2581031

We are offering copper ores. Copper is a chemical element with the symbol cu (from latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.

We are offering cobalt ores. Cobalt is a chemical element with symbol co and atomic number 27. It is found naturally only in chemically combined form. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. cobalt-based blue pigments have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought by alchemists to be due to the known metal bismuth. today, some cobalt is produced specifically from various metallic-lustered ores, for example cobaltite (coass), but the main source of the element is as a by-product of copper and nickel mining. The copper belt in the democratic republic of the congo and zambia yields most of the cobalt metal mined worldwide.

We are offering manganese. Manganese: manganese is a trace mineral that is present in tiny amounts in the body. It is found mostly in bones, the liver, kidneys, and pancreas. Manganese helps the body form connective tissue, bones, blood clotting factors, and sex hormones. It also plays a role in fat and carbohydrate metabolism, calcium absorption, and blood sugar regulation. Manganese is also necessary for normal brain and nerve function. manganese is a component of the antioxidant enzyme superoxide dismutase (sod), which helps fight free radicals. Free radicals occur naturally in the body but can damage cell membranes and dna. They may play a role in aging, as well as the development of a number of health conditions, including heart disease and cancer. Antioxidants, such as sod, can help neutralize free radicals and reduce or even help prevent some of the damage they cause. low levels of manganese in the body can contribute to infertility, bone malformation, weakness, and seizures. It is fairly easy to get enough manganese in your diet -- this nutrient is found in whole grains, nuts, and seeds -- but some experts estimate that as many as 37% of americans do not get the recommended dietary intake (rdi) of manganese in their diet. The american diet tends to contain more refined grains than whole grains, and refined grains only provide half the amount of manganese as whole grains.
