Comparative study on the effect of using conventional and ...
The effect of using conventional and high pressure grinding rolls (HPGR) crushing on the ball mill grinding of an iron ore was assessed to determine how these different comminution processes affect the ball mill grinding kinetic. For this purpose, the sample was obtained from the Jalalabad Iron Ore Mine and crushed by conventional crusher and HPGR.

Reduction kinetics of SnO 2 and ZnO in the tin ... DeepDyve
Nov 14, 2013· Therefore, these iron concentrates are still unable to be directly used as qualified blast furnace ironmaking materials. It is found that the main occurrence states of metallic elements iron, tin and zinc in the concentrates are magnetite (Fe 3 O 4 ), cassiterite (SnO 2 ) and sphalerite (ZnS), respectively ( Zhang et al., 2011 ).

Mining Industry: What is iron ore beneficiation? Quora
Oct 08, 2013· Answer Wiki. The iron content of the ore needs to be increased and gangue, which is native rock and minerals of lesser value within the ore itself, must be separated out. Methods such as screening, crushing, and grinding of iron ore are often used in various ways to purify it, along with several stages of magnetic separation.

Numerical Simulation Model For Granulation Kinetics Of ...
A numerical simulation model was developed to analyze the granulation kinetics by using the Discrete Element Method (DEM). The experiment of granulation was performed to understand the actual granulation behavior of iron ore particles. The granulation rate goes up with a decrease in a particles charge ratio and with an increase in a rotational speed [.]
