Selective destruction and differentiation of clay

1983-9-1  The grinding process is expected to destroy selectively the less resistant or less stable clay minerals from the admixture, on the basis of the difference in hardness and the initial degree of crystallinity of the individual components of such an admixture.

Mechanochemical destruction of Dechlorane Plus with ...

2010-9-1  With the increase in grinding time, the remained DP decreased and finally was completely destroyed after 4 h grinding time in the mixture with a CaO/DP ratio of 25:1 and a charge ratio of 36:1. At the same time, the water-soluble amount of chlorine increased correspondingly and reached 88.6%, demonstrating that dechlorination is the major degradation mechanism.

Dry Grinding at Barrick Goldstrike's Roaster Facility

1998-10-1  The process consists of crushing, dry grinding, roasting, extensive gas purification, calcine quenching, leaching in the presence of activated carbon and cyanide destruction. The new plant is integrated into the existing Goldstrike property treating ore from both open pit and underground sources.

H2 generation during dry grinding of kaolinite -

2004-7-1  After 600 min grinding, the band areas have decreased to about 1/4 (3694 cm −1) and 1/3 (3619 cm −1) of the initial values. This difference between the proportions of decrease indicates that the grinding reduces inner-surface hydroxyls faster than inner hydroxyls, as reported previously . Delamination of layers is considered to be the most likely cause of the faster destruction of inner

Modifying crystallinity, and thermo-optical ...

2020-10-1  It has been seen that diffraction peak around 22° becomes broad with the increase in grinding time, see the FWHM, inset of Fig. 1(d), which confirms the reduction in particle size after ultrafine grinding. The results can also be correlated with destruction of crystalline structure which leads to amorphoziation of the samples.

Effects of grinding montmorillonite and illite on their ...

2017-9-15  Grinding for more 10 min mainly exfoliated the small particles, which aggregated during the drying process accompanied with increases in the volumes of micro- and mesopores (Fig. 2c and Table 2). Exfoliation of the Ilt layer exposed the interlayer surface and should theoretically increase the DDAC content, which is contradictory to the tentative decrease of the DDAC content after grinding for 20 min

Improved extraction of alumina from coal gangue by

2016-11-1  Grinding affected changes in the particle size, bulk density, and surface area of coal gangue. SEM results revealed that coal gangue particles had undergone minimization, agglomeration, and dispersion within 20 h grinding time. The reduction in particle size and the increased surface area might improve the reactivity of coal gangue particles. (3)

Extraction of sunflower head pectin with superfine ...

2020-8-1  With superfine grinding treatment, pectin extraction can be achieved under mild condition (25 °C, pH 5.0), however, a short-time heating is necessary to avoid pectin degradation by endo-pectinase. However, due to the complex environment and the high pectin content in the extract, it is not easy to determine the accurate enzyme activity of endo-pectinase.
