Monazite has been extracted from many heavy mineral placers as a coproduct of the economic recovery of associated industrial minerals, such as titanium oxide minerals (ilmenite, rutile), zircon, sillimanite, garnet, staurolite, and others. Xenotime has been produced from some alluvial deposits as a coproduct of tin (cassiterite) placer mining.

Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2. This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

Iron (Fe) is a metallic element which constitutes about 5% of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4).. Hematite is an iron oxide mineral. It is non-magnetic and has colour variations ranging from steel silver to

At the head of First Chance Gulch in 1895, Dr. Armistead Mitchell erected a stamp mill to crush local ore. Around it grew the town of Garnet. The town was originally named Mitchell, but in 1897 became known as Garnet. An estimated $950,000 was extracted from all the mines in Garnet by 1917.

Beach sand mining is a lucrative business not only because it supplies raw materials to the construction industry but much more because it can make available minerals which are extracted from the sand, such as ilmenite (an ore for tinanium), zircon, rutile, garnet and others. They go mainly for export.

Between 1880 and 1918, twenty-three million tons of iron ore worth $73,000.000 were mined statewide, mostly in the Adirondacks. Also in this region, mines for galena for lead, pyrite for sulfur, graphite for pencils, crucibles and electrical components, garnet for abrasive, and talc, used in paint and soap, were established during this period.

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

Cassiterite is the best-known tin mineral. It has been used as the chief ore of tin from early history throughout the ages, and remains so even today. Some of the economical Cassiterite deposits exist in placer stream deposits where this very heavy mineral collects as rounded waterworn pebbles. The name Cassiterite is derived from the Greek kassiteros, meaning tin.
