Grinding is a process of reduction of lumps to powder depending on the requirement of particle size and particle shape. The present investigation involves the identify the physical properties of th...

The mass remaining was determined after 5, 10, standard hard groove grindability index (HGGI) tests were 15 and 20 min. Fig. 6. (a) EDX of untreated iron ore; (b) EDX of microwave treated iron ore for 120 s.

Wills (2006) shaker and grindability of samples were also determined. The results obtained show that weight retained varies from confirmed that particle size analysis using sieves is 36.71 g to 183.1 g for granite while that of iron‐ore vary from one of the oldest and most widely employed methods 9.65 g to 87.78 g.

Orissa Iron Ore Craton (SOIOC) hosts major hematite iron ore deposits in eastern India. Noamundi, Joda, Khondbond, Bolani, Barsua, Gua, Kiriburu and Meghataburu are the major deposits in this region. Lumps and fines are in the ratio of 50:50 and the high Received 18 February 2008. Accepted for publication 20 May 2009.

The results obtained show that weight retained varies from 36.71 g to 183.1 g for granite while that of iron‐ore vary from 9.65 g to 87.78 g. In addition, …

iron ore sample by hydraulic press on the size reduction of hematite ore lumps (sample-2). The sieve analysis of crushed product shows high weight fraction of (0.252) particles with the size range of -0.71 +0.18 mm. The variation in quantities of differently sized particle is observed in the sieve analysis.

The study shows that work index of Birnin –Gwari iron ore can be taken as 28.66 Kwh/ston i.e. 20.39 Kwh of energy is required to reduce one ton of Birnin- Gwari iron ore from 80% passing. It is hereby recommended that the value …

The influence of microwave pre-treatment on grindability of iron ore (Orissa, India) was investigated by grindability tests. SEM analysis characterized the micro-fractures in microwave treated sample.

Grinding, the first operation in the process, is a crucial step for the subsequent operations. Three iron ore mixtures with different grindability index (low, medium, and high) were used in order to verify the influence in the operational parameters such as production rate, discharge density, and pump pressure.

Standard Bond grindability tests showed that microwave heating reduced the work index of iron ores by 9.9 to 23.7 pct. Preliminary studies using a continuous feed belt in a microwave applicator indicated that samples heat more uniformly and with better temperature control than in …

M. Sinha et al. 181 er less important sources are Carbonates (FeCO 3), Sulphides (Pyrite FeS 2) and Silicates like Chamosite, Grune- rite etc. with complex chemical formulae.

The influence of microwave pre-treatment on grindability of iron ore (Orissa, India) was investigated by grindability tests. SEM analysis characterized the micro-fractures in microwave treated sample. This may be due to the thermal stress cracking resulted from microwave energy pre-treatment. XRD analysis showed the crystalline content of the ...

Iron ores containing hematite, magnetite, and geothite were subjected to microwave energy in batch operations at 3 kW and heated to average maximum temperatures between 840 and 940 deg C. Standard Bond grindability tests showed that microwave heating reduced the work index of iron ores by 10 to 24 pct.

Ores are additive if the grindability of an ore blend is the same as the weighted average grindability of the ore types in the blend (e.g., Van Tonder et al. 2010 and the references therein). To evaluate grindability of an ore with notable internal variability in mineralogy and texture, larger homogenised
