Phosphate minerals
Minerals from this group are salts of the acids containing anions (PO4), (AsO4) or (VO4). Minerals of this group have simmilar chemical formula, as changes are visible only in replacing the phosphorus with arsenic or vanadin in the various minerals. Common to this group is the merging of some of the minerals as follows - phosphorus with arsenic and arsenic with vanadin. Minerals which contain phosphorus and vanadin does not bind together. The most important representative of this group is the mineral Apatite. He can be seen in many different shapes and colours.
Minerals from this group which contain phosphorus are often used as inorganic fertilizer. The other minerals, which contain arsenic and vanadin are not very important for the industry.
Phosphate minerals
Info: Turquoise is usualy opaque, it can be translucent only when thin. The gaps on the mineral surface are covered with brown to black limonite. Transparent turquoises are very rare. Turquoise is created secondary, from a water containing copper, aluminium and phosphor. It's usualy found in...
Info: Variscite creates octaedric crystals, but it can be found in many different forms. The colour of Variscite is usualy green to emerald green. Variscite can be found in rocks rich of aluminium.
How to recognize: Variscite cannot be melted, but it can be dissolved in mineral...
Info: Vivianite is relatively easy to aquire. He is often found in prismatic crystals. Various agregate forms of Vivianite can measure up to 1 meter. Vivianite is secondary mineral, which is created near sulfidium deposits, which are near iron. Vivianite can also be created by entire...
Info: Vanadinite is often found in short collum-like crystals. This mineral is usually vine red, orange, brownish red and yellow. Vanadinite is usually found in lead mines, after oxidation. Its usually found together with pyromorphite and nimetezite, but it's very rare.
How to recognize:...
Info: Pyromorphite can be found in varios shapes, even covering some other mineral. Pyromorphite is known for his green colour, but it can be also found in the colours of orange, brown, yellow and it sometimes it can be greysh. Sometimes can be colourless or white. Pyromorphite has...
Info: Apatite is not very hard mineral, it has glassy luster, and it can be found in various colours, but only blue, purple and green are used in jewelery. Apatite is fragile and it can be found in microscopic grain crystals. This kryptocrystalic form is called kolofanite. Apatite can be found...
Info: Brazilianite is often found in prismatic crystals. It has yellow to greenish yellow colour, with glassy luster. Brazilianite is often transparent and reaches lenght of 10 cm. This mineral can be found in gaps inside pegmatite rocks, often near lazulite and apatite.
How to recognize:...
Info: Monazite is very complex mineral. It can contain lanthan, neodmium, praseodim, samarium, gadolinium, thorium and uran. Crystals of monazite often have prismatic habitus. Monazite is often translucent, and it's often coloured in the colours of yellow and brown-red. This mineral has a...
