2006-9-30 A conceptual fuzzy rule-based model was developed to evaluate the initial hydraulic conductivity of polymer-modified laterite ore slurries. Based on expert judgment, the model correlated well with bench-scale settling test data and the predicted k i of polymer-added laterite ore slurry gave an R 2 = 0.75. Rank correlation coefficient-based ...

2012-9-10 Concentrated iron ore was donated by a Lake Superior District iron ore concentration plant. The concentrated ore was washed with distilled water in a pressure filter until the filtrate had a conductivity of less than 100 μS/cm in order to remove ions on the surface of the hematite particles.

2009-7-1 Finally, the pH of process water for the marginal ore was 7.5 while the conductivity was 3.9 mS/cm. For the B-type ore, process water had a conductivity of 0.44 mS/cm and a pH value of 7.8. For comparison, the conductivity of a saturated calcium sulfate solution was found to be 2.8 mS/cm (pH 6.9), as measured in a separate test. 2.3.

Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia. Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits (BID), Channel Iron Deposits (CID) and Detrital Iron Deposits (DID), mixing the feed to obtain the product under contract.

2020-6-11 throughout iron ore production is critical. Currently, the primary method of measuring moisture content in mineral industry is taking a certain mass of sample to the laboratory, weighing the sample without drying and reweighing it after 100% water evaporation. Water content is simply the mass difference between the two tests.

The part of the bedrock that is not iron ore is called gangue. To obtain the iron, one must first separate the ore from the gangue. The ore is crushed and rinsed to remove most of the gangue in a processing plant. Then you get a kind of wet sand called slurry which has a high iron content - over 60 percent - in a form called 'iron ore fines ...
