Widely used types of minerals are gems ores precious stones etc. However these mineral types lack solid definition and they are often mixture of various minerals with different chemical and physical properties. Scientists mostly use Strun classification based in mineral chemistry and crystalography.
An ore is a special type of rock that contains a large enough amount of a particular mineral usually a metal to make it economically practical to extract that mineral from the surrounding rock

The more concentrated an ore mineral the more valuable the mineral deposit. For every mineral deposit there is a set of conditions such as the level of concentration and the sie of the deposit that must be reached if the deposit is to be worked at a profit.

The first genetic classification of ore deposits to win wide acceptance was that initially proposed by Waldemar Lindgren in 1906 and last revised by him in 1933. As ideas on the genesis of ores have undergone change in the thinking of geologists the Lindgren classification has come under attack mainly by two groups.

In Mineral Processing the SPIRAL Classifier on the other hand is rotated through the ore. It doesnt lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do.

Rare Earth Ore Classification. Classification of ores related to alkaline rocks is also controversial. Table 2 presents a relatively simple classification that follows analogous categories for deposits related to nonalkaline igneous rocks. Some of the more unusual alkaline rocks that host or are related to REE ores are carbonatite and phoscorite igneous rocks composed principally of

A mineral with visible layers like Rhodochrosite has a banded habit. Amethyst has a drusy habit where jagged projectiles line a rocks interior. Close observation and perhaps a magnifying glass are all you need for this step in the mineral identification process.

In another common method of classification ore minerals are divided into hypogene also termed primary deposits and supergene also known as secondary deposits. The secondary deposits are formed as alteration products of primary deposits through weathering and related processes. An ore deposit may be either of igneous or of sedimentary origin.
