"A Mexican clay, intended to be used as refractory raw material, was identified. Problems encountered in the characterization of halloysitic clays are discussed and emphasis is made on the use of the electron microscope (scanning or transmission type) as a definite evidence of the existence of halloysite due to its unique morphology within the kaolinite group of clay minerals.
Beneficiation of this particular clay was carried out on a small scale hydrocyclone equipment and the results are discussed.
In an attempt to increase the green density in dry pressing of this halloysitic clay, mixtures with grog were prepared using different additives, grinding and low temperature preheating treatment. The effect of these variables upon green density is given and discussed.
It is believed that an increase in the dry pressing density will be reflected in better after burning properties of bricks made out of clays.
Pressure levels in the dry pressing experiments were made in a range similar to an industrial power press production"--Abstract, page ii.
