Is sphalerite a mineral or a rock.

A nonmetallic mineral that is grey, grey-green, white, or blue in color, has 2 perfect cleavage planes at 90° with one plane showing striations (a growth pattern that appears as thin grooves), and a hardness of 6.0. The iridescent blue variation is known as Labradorite. Click on image to see enlarged photo.The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (e.g., S 2–)) or an anion complex (e.g., SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their …Geodes are spherical masses of minerals that were deposited syngenetically within rock formations. Inside the chalcedony shell minerals are such as calcite, ...The other mineral that can carry significant indium in base metal ores is chalcopyrite (e.g., Gaspar, 2002).Concentrations of indium are, however, lower than in co-existing sphalerite (e.g., Cook et al., 2011) where the two minerals co-exist, suggesting a strong fractionation into the zinc sulphide.Chalcopyrite can potentially account for a …

Figure 3.5.5 3.5. 5: Limonite, hydrated oxide of iron. After carbonates, the next most common non-silicate minerals are the oxides, halides, and sulfides. Oxides consist of metal ions covalently bonded with oxygen. The most familiar oxide is rust, which is a combination of iron oxides (Fe 2 O 3) and hydrated oxides.

In a given chemical class, each mineral contains the same specific element or chemical compound but in combination with different metals. For example, galena (PbS) and sphalerite (ZnS) are both sulfide minerals, but galena contains lead and sphalerite contains zinc. The minerals of Ohio are grouped into ten chemical classes:
