Concentrates, Tailings
and Middling and Grade
Concentrates are the enriched
mineral products of ores after beneficiation to remove most of the gangue and
impurities. Concentrates are the final product in the processing plant,
sometimes called final concentrates. Concentrates can be qualified only if when
both the main components and impurities reach the national standard.
For example: K-feldspar
(potassium feldspar) for ceramics, in accordance with the general industrial
standards, K2O + Na2O content must be greater than or equal to 11%,...

Reduce-Fe Type
Application of DLS High Gradient Magnetic
Separator, Reduce Iron type:
Purify quartz,
feldspar, silica sands, kaolin, clay, nepheline, fluorite, sillimanite,
andalusite, kyanite, etc. Remove iron, biotite, managnese, hornblende, mica,
tourmaline, garnet and other impurities
1. Why use high gradient magnetic separator to purify feldspar?
Whiteness/brightness is a key index in the industrial purpose feldspar. In the
run...
Test Report: Remove Fe & Ti
in Coal-series Kaolin
The sample is coal-series kaolin from Xiangtan, black powder blocks, with small stones
and other impurities in it. Purpose of the test is to remove Fe and Ti in it.
Coal-series kaolin mainly existed in the top/bottom/interlayer of coal
layers of coal-series stratum formed in the Permian of carbon and the coal
series of Carboniferous, Triassic, Jurassic and Tertiary,...
Useful minerals
vs Gangue
Useful minerals
are minerals, ores and rocks that can be used (with economic benefits).
Gangue: In
addition to the useful minerals, there are some minerals in the ore that can
not be enriched or used at present, which are called gangue, such as hematite, biotite, amphibole in feldspar; high gradient magnetic
separator is used to separate feldspar and gangue.

Rock vs Ore
vs Mineral
Minerals are integral part of the rock or ore; they are
elements of nature or natural compounds with fixed chemical composition and
physical and chemical properties, after natural physical and chemical effects
and biochemical effects in the earth's crust. Most of the minerals are natural
compound, such as magnetite (Fe3O4),
quartz (SiO2), a small parts are
natural elements, such as the nature of gold (Au), silver (Ag), copper (Cu),
graphite (C), etc....
