Extraction of Metals | Good Science

Metals with an intermediate reactivity, such as iron and zinc, are chemically extracted from minerals by a process known as carbon reduction. Carbon reduction is a type of redox reaction, where carbon is used to displace a metal from a compound. The crushed ore is mixed with carbon and limestone, then heated to a molten state (smelted) in a

calcium stearate by the rubber companies. There is also increased interest in the magnesium stearate as well. Stearates, in general, are thought of as a salt. This salt, or soap of a stearic acid is formed by replacing the carboxylic hydrogen by a metal to yield a salt (see Figure 1). C 17-H 35-C-O-(metal) O or -(R) Fig. 1. Carboxylic hydrogen

Alkaline Earth Metals Reactions, Uses, Properties

These metal hydrides can emit hydrogen gas when they react with compounds which can supply H + ions. As an example, when calcium hydride is added to water, calcium hydroxide and hydrogen gas are given as products. Halogen and alkaline earth metals. Alkaline earth metals react with halogens and form halides. This reaction is a exothermic reaction.
