This document discusses several minerals including copper, zinc, lead, talc, and graphite. It provides introductions and properties for each mineral. Copper's introduction includes its elemental symbol, atomic number, atomic weight, heat conduction and melting/boiling points. Copper properties noted are its reddish color, malleability, ductility, conductivity, natural occurrence in minerals, isotopes, and ability to form alloys. Similar introductions and properties are provided for zinc, lead, and graphite. The document also mentions that talc and these minerals are found in Sikkim.

2. MINERALS
1) Minerals are solid substances that are present in nature and can be made of one
element or more elements combined together
2) Minerals are usually solid , inorganic , have a crystal structure , and form naturally
by geological processes
A mineral can be made of single chemical element or more usually a compound.
There are over 4,000 types of known minerals.Two common minerals are quartz and
feldspar.
3) Mineral has a definite chemical make-up
4) The study of minerals is called mineralogy
