In upgrading lean tungsten ore, gravity concentration by jigging of vein quartz produced a pre-concentrate containing 4.5 wo 3.For further upgrading the pre-concentrate, beneficiation studies were conducted with an objective of obtaining a product analysing 65 wo 3 with less than 1 impurities of sio 2 and s each.The sample contained quartz, topaz and iron sulphides as gangue.The study.
Abstractmineral and morphological characteristics of chromite ore strongly affect the separation efficiency while upgrading the low-grade deposits.Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals.However, chromite ore from sukinda region, india, is a typical ore body with high iron content in.
A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding.The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated.The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.
Manganese ore, mostly belonging to lean ore, must go through the dressing processmost of the manganese ore stones are embedded in fine grain or subtle grain form and there are a number of high phosphate rock, high iron ore and symbiotic beneficial metal.For above two reasons, dressing process has great difficulty.
