In this study, surface modification of calcite was examined using a laboratory stirred ball mill in wet condition. A fatty acid collector, sodium oleate (oleic acid sodium salt), was used as the modifying agent. Surface modification of the ground calcite sample was studied as a function of sodium oleate dosage, time and pH.

In the milling process, the carboncontaining interlayered impurities were separated and removed; the optimal milling time was 22 h. In the hydrothermal process, the brightness of calcite powders with sulfate modifiers were equivalent to that of those without crystal modifiers, while the powder crystallinity was distinctly reduced with the Na 2 ...

Generally speaking, the finished product size below 1500 mesh is generally produced by dry grinding process. For product size from 1500 to 2500 mesh can be produced by dry gridning process or wet gridning process. For products from 2500 to 6500 mesh, wet grinding process is usually appropriate for production. Ground calcium carbonate.

One of the most energyintensive processes for producing submicron range calcite is stirred media mill. In the present work, numerous operating parameters such as solid mass fraction, grinding media size, media filling ratio, and grinding time have been investigated using a vertical type stirred media mill. The results are evaluated on the basis of mean particle size, specific surface area ...
