Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantitetetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.
Silicon prefers above all else to surround itself with four oxygen atoms as if in the orthosilicate ion (SiO 4). This ion actually exists in water solution, forming the weakly ionized orthosilicic acid, H 4 SiO 4, with ionization constant K 1 = 2 x 10 10 .
The flotation tests on the single minerals of fine fluorite and quartz (all less than 10 μm) as well as mixed minerals were conducted using water glass (WG) (with modulus ranging from to ) as depressant and sodium oleate (NaOl) as collector.
Silicate Mineral Class Lecture exam #5 will include concepts in AD inclusive A. Introduction silicates are the most abundant class of minerals comprising 75% of all known minerals and 40% of all common minerals
In the near pure state of only silicon and oxygen the mineral is quartz (SiO2). But the tectosilicates are not that simple. It turns out that the aluminum ion can easily substitute for the silicon ion in the tetrahedrons up to 50%.
The terms mineral and rock are often confused. They are frequently used together, and the materials they describe are closely related. In general, a mineral is a naturally occurring, inorganic, chemical element or a group of elements (a compound).

If a sodium ion with a 1+ charge substitutes for a calcium ion with a 2+ charge, a balancing substitution of an aluminum ion with a 3 charge for a silicon ion with a 4 charge will also occur. The relative abundance of sodium and calcium in melts varies greatly, and the full series of mineral compositions between pure sodium plagioclase and pure calcium plagioclase does occur.

Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO4 silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.
