if the mill is rotated too fast, the balls can be thrown too far and just strike the far end of the mill and conversely, if the mill is rotated to slow, the efficiency of the grinding process significantly reduced. ball mills are suited for finer grinding as larger particles do not impede the impact on to smaller particle as in rod mills.

3.1 chrome magnetic separation process. the chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. the dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. first of all, magnetic separation processing to separate chromite.
the beneficiation process of chrome. the mining chrome ore is firstly crushed into proper granularity via the jaw crusher. then, the crushed ore will be delivered to the storehouse through the hoist. the next step is to send the chrome ore to the ball mill, and the ball mill will grind it further. the ground fine chrome material then will put
jan 03 2012 0183 32 so from the beneficiation studies on the off grade chromite ore revealed that the cr 2 o 3 content can be upgraded to 489 with cr fe ratio of 231 by gravity concentration whereas the product quality can be enriched to 523 cr 2 o 3 with cr fe ratio of 335 by using magnetic separation...

during the beneficiation of chromite hosted pge’s by froth flotation, chromite represents the principal gangue mineral. this is particularly true for the ug2 main seam. an excess of more than 3% in mass of chromite in the pgm concentrate is known to result in significant problems in the downstream processing and extraction of pges.
chromite beneficiation process. mar 19, 2017 chromite grinding the 36″x 8′ adjustable stroke ore feeder is used to accurately control feed of crushed ore to the grinding section before it is fed to the 4’x 8′ peripheral discharge rod mill, the minus ¼” chrome ore is removed from the grinding circuit by means of a 4’x 12′ dillon vibrating screen this minus ¼” product

effect of milling on the beneficiation of chromite. beneficiation techniques for chromite ore mining in sa chrome ore dressing methods in south africa chromium in south africa saimm feb 2 1986 the marked changes in international trade in chromite ores during the past ten to fifteen years and to the of south african ore is still exported to meet the demands for the production run of mine ore
abstract mixtures of chromite, graphite and various additives were reacted isothermally under argon, and the loss in mass was recorded continuously. the additives used, sio 2 , al 2 o 3 , k 2 co 3 , na 2 o 2 cao, mgo, fe and cr, all influence the boudouard reaction positively. of these, only mgo and al 2 o 3 revealed an inhibiting effect during the carbothermic reduction of chromite.
the effect of size reduction on the liberation of particles was investigated by means of microscopic examinations. the study showed that whether in its pure or partially separated form, chromite and gangue minerals mingled in different size fractions. as can be seen from the fig. 2, chromite is distributed almost evenly in
