Jan 10, 2020 The Bond work index for B and C type iron ore sample are of 11 and 10 KWhmt. The variation of BWI of three iron ore sample may be varied during the geological formation of each iron ore sample. The output product of three iron ore sample composed of three different size fractions when ground in Bonds ball mill.
And thus, the grindability of the iron ores was investigated. The results obtained are as follows 1 The work indices of the iron ores are ranged from 6.22 to 17.40. The work indices of the Santa Barbara ore, the Santa Fe ore and the Chile ore are greater than 17 and these ores are remarkably hard.

index, pilot plant INTRODUCTION The resistance of ore samples to breakage or hardness is measured through grindability testing. Several grindability tests have been developed over the years for different applications and each test has its own strengths and weaknesses. Grindability testing is a compromise between test cost and its deliverables.
index test obtained high work index 52.60 kw.ht and consumed power 11.72 kw.ht to grind one ton of low grade iron ore and this attributed to the high concentration and hardness of quartz mineral which is considered the main gangue of the ore in study area .
Grindability Work Index For Iron Ore haagdeko.de. The Work Index Of The Iron Ore. 2009-6-5the work indices of various iron ores in the world were measuredrom the values of the work indices of the iron ores, the powers required to grind the iron ores were estimatednd thus, the grindability of the iron ores was investigatedhe results obtained are as follows 1 the work indices.
correlation was found between crushability and grindability for the same samples. The grindability showed inverse correlation with both magnetite grade and the magnetites mineral grain size. The preliminary conclusion is that modal mineralogy and micro-texture grain size can be used to quantitatively describe the ore comminution
Platts Iron Ore Index assessments reflect the tradeable price of iron ore at 5.30pm SingaporeBeijing time 9.30 am GMT. The IODEX assessment is not origin specific, and takes into account ores with iron content between 60-63.5 Prior to 2012, the spot market saw Indian material traded most actively this shifted, with Australia being the main source of spot medium grade fines material.
Modbond Grindability Test. Similar to a Comparative Work Index, this test is an open circuit dry batch grindability test run in the standard Bond Ball Mill for a set time. It can be used at mesh sizes from 65 to 200 mesh normally 100 mesh. The test requires calibration against the standard Bond Ball Mill Work Index test to estimate the Work ...
Copper Ore Grindability Test. Grindability index of uranium ore differences in values of the bond work index of grindability for lowgrade copper ore of 54 kwht or about 42 and highgrade copper ore of 377 kwht or about 35 from the point of the theory of comminution and practical application in designing and selection 12 kg of minus 6 mesh ore bond ball mill.
Samples of iron ore were sourced using random method, reference minerals marble and granite of known weight and iron ore of known weight were ground using the laboratory ball mill

The influence of reduction roasting and thermal shock on the grindability of a refractory low-grade Michigan iron ore was examined in bench-scale tests. The quantitative effects of the various treatments were evaluated at three sieve levels, 48, 100, and 400 mesh, with ball-mill-grindability and work-index parameters as response indicators.
sized feed of about 50mm and crusher setting CSS of 5mm. The grinding runs were in form of grindability tests carried out at 212microns to compare autogenous and media assisted grindability of the ore Venkatathanan and Degaleesan, 1982. Details of the grindability tests are contained in another article but the effects are
Selection of iron ore crusher - puntoalloggioron ore crusher selection criteria work grindabilityf ore grindability are the bond work index the bond test, and thus is useful for the design and selection of crushing, requirements and for selection of plant scale comminution, dolomite, iron ore, coal and limestone by using a variac.
Comparative Analysis of Grindability of Iron-ore and . This implies that Granite is harder than IronOre, as confirmed by Wills 2006 who stated that Ore grindability refers to the ease with which materials can be comminuted. Adedeji, F. A.
Jul 01, 2013 Grindability of granite and Iron-ore was investigated in this work. Samples were collected from Julius Berger Quarry and National Iron-Ore Mining Company NIOMCO, Itakpe. Particle size distribution of the samples by means of sieve shaker and grindability of samples were also determined. The results obtained show that weight retained varies from 36.71 g to 183.1 g for granite while that of ...

Of Reducibility Of Magnetite Iron Ore. Iron ore pellets and Pelletiing processes ispatguru. Feb 23 2013 Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the same both in the blast furnace and for DR production Pellets have good reducibility since they have high porosity 25-30
Jan 26, 2017 The pulsed power is a potential means for energy saving and presents an alternative to the conventional mechanical communication for minerals. The effect of magnetic pulse treatment on grindability of a magnetite ore was investigated by grindability tests. The results of the investigation show that the pulsed treatment has little effect on the particle size distribution of the magnetite ore.
