A Grinding Ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Stone coal was exposed to the two stages of flotation processes to recover vanadium microelement. Mineral composition of coal was calcite, barite, quartz, and V-minerals. Reagents were sulfuric acid (pH regulator), oleic acid (Ca minerals collector), sodium silicate (dispersant), sodium fluorosilicate (SFF and depressant), melamine (EA and V minerals collector), dodecyl amine (DDA and V minerals collector), octadecylamine (DC and V minerals collector, terpenic oil (frother)). pH was kept between 7 and 8, and water glass was used as depressant (2000g/t). Besides, oleic acid was taken 200g/t as collector .
The HGMS adopts a rotating ring vertical rotation and recoil concentrate, and a high-frequency vibration mechanism. It fundamentally solves the worldwide technical problem that the magnetic material of the flat ring strong magnetic separator and the flat ring high gradient magnetic separator are easy to block.
Continental volcanic-intrusive iron ore deposits are mostly associated with middle- or medium-acid volcanic rocks and are mainly produced in volcanic clasts or in the contact zones within and around the pluton. The mineralization age is Mesozoic. It is mainly located in Ningwu-Luzong area, often referred to as “porphyrite iron ore”. In addition, the Jiaduoling iron ore deposit in Tibet and the Liangzi iron ore in Sichuan Province are also known as continental volcano-intrusive iron deposits.
In Peru,there is about 57.9 million tons of copper ore reserves, they are mainly in arequipa, ancash, limacallao, cuzco and tacna and some other provinces.For the differences of these copper ore deposits, the copper ore beneficiation plants in Peru is quite different from each other. Copper is essential to the functioning of society and has played important roles in society for thousands of years. It is present in almost every modern household item that uses electricity. Copper is a soft, malleable and ductile metal. Copper readily form compounds and while it does oxidise or tarnish it does not do so as readily as other metals. Copper is a good conductor of heat and electricity. It is a better conductor than most metals. Silver is a better electrical conductor but copper has better corrosion resistance and is a more abundant and hence cheaper material to use.
The counter–rotation tank style is preferred for heavy media applications. The drum rotates against the slurry flow in the counter–rotation tank style. The slurry enters the feedbox and flows directly into the magnetic field generated by the drum. The magnetite is attracted by the magnetic field, collected on the drum surface, and rotated out of the slurry flow. Any magnetite that is not immediately collected will pass through to a magnetic scavenging zone. The short path that the magnetic material must be conveyed between the feed entry point and the magnetics discharge lip, combined with the magnetic scavenging zone, results in high magnetite recoveries.

ESW-1.0 laboratory bead mill is a small wet grinding machine, designed and developed for user doing experiments or small batch production.
Kawatra performed experiments on fresh coal and 1-year aged coal for different conditions. Fresh coal substances were exposed to different pH levels, and the percentage of froth weight being in directly proportional with floatability of pyrite were investigated. pH levels were defined as 8.3, 7.5, 2.3,2.2, and 2.0, and froth weights were found as 5, 4, 98, 98, and 99%, respectively. On the other hand, same procedure was applied on 1-year aged coal at -15°C, and lowest weight was attained around 37% when pH was almost equal to 6.8, whereas pH was dropped to 2.0, achieved weight dramatically increased, and equal to 92%. Lastly, 1-year aged coal substances were heated up to 100°C and tested in pH level 6.2 and 2.0, and results were 7% and 82%, respectively. From the results, it can be understood that freshly ground mineral pyrite is not readily floatable at neutral pH despite of being highly floatable in acidic pH.On the other hand, pyrite oxidation concludes with sulfate formation, which is not hydrophobic. If necessary conditions might be satisfied for forming elemental sulfur, pyrite can be floated. Also, it is shown that under certain condition, pyrite can be floated at neutral pH, but that is not a normal case. .
Mill recoveries are expected to average 96.5% over the life of mine, consistent with the historical performance of the existing operation.
The refining action is accomplished by a special cooled shaft with agitator arms and diverters rotating in a vertical jacketed grinding tank, which is filled with hardened steel balls.
