The present disclosure relates to the field of chemical compounds, compositions and processes. More specifically, the present disclosure relates to compositions having a high-loading capacity in an aqueous medium and to compositions, processes and uses thereof as silica coagulants in hydrometallurgical process streams.

Agents for use in hydrometallurgical process streams

The present disclosure provides a froth flotation composition including a cycloaliphatic alcohol and a reaction product of the cycloaliphatic alcohol and propylene oxide. The froth flotation composition is especially suited for use in ore and coal flotation processes.

Composition for application as a flotation frother

This idea relates to the use of polyalkylene glycols and non-salt polyether amines to improve the effectiveness of silica removal by coagulation and agglomeration of colloidal silica particles in aqueous mineral process streams.

Compositions and methods for coagulating silica from mineral processing streams

Compounds of formula (I) wherein Rand Rare each independently C-Calkyl, and m is 1, 2, 3, 4, or 5 and compositions of formula (II) wherein Rand Rare each independently C-Calkyl, and n is an integer &#x3e;_0 and wherein the average molar value of n for the total of the compounds of formula (II) in said composition is in the range of (1) to (3) and methods for production thereof.
