The term "enrichment factor" is used to describe bodies of substances like mineral ore. It is based on the minimal amount at which the weight percentage of a mineral in an ore is greater than its average occurrence overall within the Earth's crust. This information is typically used to determine whether it is cost effective to mine and recover various substances before any action takes place.
It is true that the continent of Africa has a wealth of mineral resources. Whether this should be interpreted as a blessing from God, is open to debate.
Cyanide is not a substance in itself but refers to a radical -CN which attaches readily to elements such as potassium and sodium to form such compounds as potassium cyanide KCN, and sodium cyanide NaCN, both of which are extremely poisonous. In any case, these compounds are known as salts and could be considered minerals whether or not they are naturally occurring.

A mineral is any chemical compound with a constant chemical composition, which of course is the definition of a "pure substance". In earth science you might be distinguishing between "rock" and "mineral". A mineral is a pure substance. A rock is a mixture of two or more minerals in various proportions. For instance, the rock granite is made up of three minerals: quartz, feldspar and biotite (mica).

A reagent is a chemical substance that reacts with some other substance. It is common to add a specific reagent to an unknown substance to determine whether or not the substance that the particular reagent reacts to is present. (For example, add a reagent for sugar to test for the presence of sugar.)
