What Tests Do Scientists Use to Identify Minerals ...

The way a mineral looks reveals much about its texture, composition and history. Minerals can be classed according to their luster. They can be classed as metallic, glassy or dull, with certain intermediate classifications such as waxy or adamantine. Another clue that can be found with a visual examination comes from the mineral's color.

Spiral Classifier for Mineral Processing

Aug 05, 2015· The other problem that these classifiers have is that they are easily over loaded. A over loaded classifier can quickly deteriorate in to a sanded up classifier. Once that happens the results are lost operating time, spillage and a period of poor Mineral Processing and Separation performance.

Hydrocyclone - Wikipedia

A hydrocyclone (often referred to by the shortened form cyclone) is a device to classify, separate or sort particles in a liquid suspension based on the ratio of their centripetal force to fluid resistance.This ratio is high for dense (where separation by density is required) and coarse (where separation by size is required) particles, and low for light and fine particles.

A Guide to Gem Classification - International Gem Society

These impurities don't change the primary chemistry. Therefore, the mineral name, or species, doesn't change. They do, however, change some of the mineral 's characteristics, so we use a sub-classification called a variety. Changes in characteristics such as appearance can have a considerable effect on a gem mineral's value.

Metamorphic Rocks - What Makes Them Change

Metamorphic rocks are one of the three types of rock classifications, the other two being igneous and sedimentary. Rocks are classified by the processes under which they were formed. The differences in formation account for variations in the appearance of the rocks and, with some practice, you can learn to recognize the different types by sight.

Hydrocyclone Working Principle

An air classifier is an industrial machine which separates materials by a combination of size, shape, and density.. It works by injecting the material stream to be sorted into a chamber which contains a column of rising air.Inside the separation chamber, air drag on the objects supplies an upward force which counteracts the force of gravity and lifts the material to be sorted up into the air.
