Minerals magnesium

Meteorites are generally divided into three broad groups according to their chemistry and mineralogy that is, stones, stony irons, and irons (Chapman, 1999, 353 Dalrymple, 1991, 264). As the name implies, stony irons are meteorites with intermediate compositions between irons and stones (Dalrymple, 1991, 264). Stones mostly consist of carbonate minerals, magnesium- and iron-rich silicates, and/or other nonmetallic...

Magnesium has seen widespread use in citrus fertilizers, especially in Florida, for many years. It has been shown that the magnesium requirement for citrus trees is fairly small until the tree bears fruit (Spencer and Wander, 1960). Spencer and Wander also demonstrated that there is a definite relationship between the quantity of extractable magnesium in the soil and the amount taken up by the tree and hence the leaf magnesium content. They also determined that MgO derived from seawater magnesia was superior to Mg derived from olivine, dolomite, or kieserite, especially on acid sandy soil. On neutral soil, the use of MgS04 is indicated and provides Mg rapidly to the plant see Table 13.1 for a comparison of mineral magnesium fertilizers.

Talc - Talc is a filler made by dry or wet grinding of mineral magnesium silicate. Talc improves stiffness, dimensional stability, flexural modulus, creep resistance, flow, surface smoothness, moisture resistance, tensile strength, and wear resistance of plastics. It also increases heat deflection temperature and decreases vapor permeability. Can be used as a film antiblock agent. Used mainly in polypropylene but also in thermoplastic and unsaturated polyesters and epoxy resins at low levels. Surface-modified grades are available.

In addition to potassium, some studies have shown that the minerals magnesium and calcium may also have a positive influence in maintaining healthy blood pressure. The fruits and vegetables that provide potassium in the diet are also good sources of these two minerals. So, the parental directions traditionally given to children to eat your fruits and vegetables and drink your milk have been given scientific validity for all of us as a way to help maintain healthy levels of blood pressure.
