Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores
The recovery of fine hematite particles from banded hematite quartzite (BHQ) ore with potato starch has been investigated using selective flocculation. Microscopic features, coupled with x-ray diffraction (XRD), and Fourier transforms infrared (FTIR) spectroscopic data provide evidences for adsorption of starch molecules on hematite surface. The starch molecules show good selectivity for hemati...
متن کاملSelective Flocculation for Coal De Mineralization
Selective flocculation has long been suggested as a method for the treatment of ultra-fine particles typical of which are those produced in a de-sliming process ahead of flotation. In this paper the results of the coal de-mineralization, using synthetic polyacrylamide polymers, are presented. A prescreening test on the suitability of the polymers using Run-Of-Mine (R.O.M.) coal and artificial m...
متن کاملStudy of Membrane Fluidity of Acidithiobacillus ferrooxidans on Different Ores (Pyrite and Hematite)
Cell membranes are key structures existing in all living organisms in the world. Their importance in biology and medicine has been clear for many decades, and an extensive body of research for all aspects of their structure and function. They are ubiquitous in biology and are central to understanding key problems in biology and medicine (Lodish et al., 2000). All biological membranes are fluid ...
متن کاملOrigin and Timing of Banded Iron Formation-Hosted High-Grade Hard Hematite Deposits—A Paleomagnetic Approach
The processes responsible for the transformation of banded iron formations to hard high-grade hematite ore, and their timing, remain poorly understood despite many recent advances. The paleomagnetic method allows for the estimation of ore genesis timing as a complement to other techniques. The effectiveness of the paleomagnetic method at dating, and testing proposed models for, the genesis of h...
متن کاملAnalysis of Hyperion Satellite Data for Discrimination of Banded Magnetite Quartzite in Godumalai Hill, Salem District, Tamil Nadu, India
In order to determine mineralogy of rock and soil samples, reflectance and emittance spectroscopy in the near-infra red and short-wave infra-red is used extensively and found to be inexpensive. Hyper spectral remote sensing satellite data are found to be prospective to deliver in depth physico-chemistry like mineralogy, chemistry, morphology of the earth’s surface. Therefore hyper spectral data...
