Abstract The effects of dodecylammonium chloride on properties of quartz slurries that are relevant to grinding, such as pulp fluidity, flocculation and dispersion, and primary breakage, have been investigated in this study. These tests were conducted under chemical conditions (pH, ionic strength, additive concentration, etc.) similar to those used in wet ball milling tests.

This is important because calcite is known to transform to aragonite on grinding (see e.g. Lin et al., 1975), and aragonite dissolves in water more rapidly than calcite. A study of the adsorption of dodecylamine on calcite recently reported by Cases et al. (1975) shows that grinding completely alters the shape of the isotherm.

In some ores, calcite is present in moderate quantities along with silicates. In such cases, silicates or sulphides associated with calcite are floated using amine surfactants (Hanna 1975).All these experiments were performed at alkaline pH; if silicates or sulphides were present in the ores, these were floated before the separation of scheelite and calcite was performed.
