How are they aquired?
Magnesium Products- Magnesium, an abundant mineral in the body, is naturally present in many foods, added to other food products, available as a dietary supplement, and present in some medicines (such as antacids and laxatives). Magnesium is a co factor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation
Potassium- Potassium can be found in vegetables it is in the human body. Adults should aim for about 4,700 mg f potassium per day.
Tamtalum Products- The use of tantalum has expanded dramatically since the 1940s as a result of major advances in electronics. The principal source of tantalum until the 1990s was tin mining, where tantalum was extracted as a by-product. By the 1990s the main source of tantalum came from the extraction of specific tantalum ores in different parts of the world.
Zirconium Products-In the late 1700’s, the German chemist Martin Heinrich Klaproth suspected that there was a new element to be found in this mineral. He reduced the mineral zircon to zirconium oxide in 1789, but never isolated the metal. In 1824, Swedish chemist Jöns Jacob Berzelius isolated an impure zirconium metal, but it wasn’t until 1914 when pure zirconium was finally produced.
Process of Chrome Metal
- Degreasing to remove heavy soiling
- Manual cleaning to remove all residual traces of dirt and surface impurities
- Various pretreatments depending on the substrate
- Placement into the chrome plating vat, where it is allowed to warm to solution temperature
- Application of plating current for the required time to attain the desired thickness
