introduction this mineral key is designed and intended for use on-line. the premise behind this key is similar to that of the identification keys found in some fern and wildflower books: key diagnostic properties are used to direct users to tables where further information on "likely suspects" is found.
jun 26 2019 0183; 32;the name of both these compounds already suggest this difference the other key difference between both these type of mineral is that metallic minerals are melted to obtain the new or useful product whereas non-metallic minerals do not yield new products upon melting.

jun 13 2019 0183; 32;key differences. the structure of metallic minerals is such as that they have a shiny surface and at the same time has a harder tinge on them. on the other hand the structure of non-metallic minerals does not have any shine and have a structure that may become rigid but not that hard.
section iii: minerals with a non metallic luster & hardness greater than 5 189;. step 12 can the mineral be scratched by a sharp quartz point? (hardness less than 7?) yes - [go to nonmetallic luster key (hard): step 13] no - [go to nonmetallic luster key (hard): step 14]
dec 02 2015 0183; 32;the key difference between metallic and nonmetallic minerals is that metallic mineral is a combination of minerals that can be melted to gain new products whereas non-metallic minerals are a combination of minerals that do not produce new products on melting.
-"luster" is the term geologists use to describe how light is reflected from a mineral's surface-minerals containing metals are often shiny-many terms are used to describe the luster of a mineral;including metallicglassywaxypearly greasydullsilky and earthy
minerals are not equivalent to rocks. a rock is an aggregate of one or more minerals or mineraloids. some rocks such as limestone or quartzite are composed primarily of one mineral – calcite or aragonite in the of limestone and quartz in the latter case. other rocks can be defined by relative abundances of key (essential) minerals; a granite is defined by proportions of quartz ...

mineral properties. in order to use this key and the test kit described above you need to understand some basic properties of minerals. the most important are: luster streak hardness and cleavage.
metallic - minerals with a metallic luster are opaque and reflective like metal. the metallic elements most sulfides and some oxides belong in this category. submetallic - describes a mineral that is opaque to nearly opaque and reflects well. thin splinters or sections of submetallic minerals are translucent.
metallic minerals are commonly shiny and opaque even on thin edges. (important note: just because a mineral is shiny doesn't mean it's a metal.) non-metallic: doesn't look like a metal. there are many subtle differences in the non-metallic lusters but most are relatively dull and are often transparent to translucent on thin edges.

(tsx-v: mmg; ... assessing these structural orientations along with the potential structural windows in the key host rocks is an important factor in exploration on the advanced-stage targets and assists in prioritizing among the early-stage target areas.
dec 29 2017 0183; 32;key differences metallic and non-metallic minerals. the difference between metallic and non-metallic minerals can be drawn clearly on the following grounds: metallic minerals can be understood as the minerals in which metals are present in their original form.
non-metallic mineral products comprise of the production of cement ceramics glass and lime. these manufacturing sectors are characterised by the transformation of naturally occurring minerals such as limestone silica and clays through an energy‑intensive process.
