The manufacturing process known as plating includes many steps and requires considerable pretreatment, treatment and post-treatment steps. While there are several different kinds of plating techniques, this how-to guide is intended to provide the basic procedural steps for the most popular plating process, electroplating. Step 1: The Mechanical Finishing Pretreatment Process

manganese processing, preparation of the ore for use in various products.. Manganese (Mn) is a hard, silvery white metal with a melting point of 1,244 °C (2,271 °F). Ordinarily too brittle to be of structural value itself, it is an essential agent in steelmaking, in which it removes impurities such as sulfur and oxygen and adds important physical properties to the metal.

Magnesium, an imbalance of magnesium and calcium. It'll displace the calcium in the plant, and that in turn causes the plant to stunt its growth. So you wanna basically be low on magnesium, and high on calcium, not the other way around. If it is high in calcium, that's the sign of a territory that's high potential for gold.
