Diagnosis of the Surface Chemistry Effects on Fine Coal Flotation Using Saline Water

In the present investigation, two coal samples were obtained from a typical Australian coal flotation plant using saline water and examined to identify surface chemistry effects on fine coal flotation which is an important issue confronting the coal industry. The speciation modeling indicated that hydrophilic precipitates may occur in the flotation circuits as a result of the use of high ionic strength water, negatively impacting the coal flotation. Meanwhile, Cryo-SEM (scanning electron microscopy) detected the presence of clay minerals on the coal surface which has a deleterious effect on the flotation. Surface oxidation was also found on both coal samples by XPS (X-ray photoelectron spectroscopy) analysis and well correlated with their flotation behavior. This study suggests mitigating the slime coating and addressing the oxidized coal surface simultaneously to improve the coal flotation.

Surface & Interface Analysis

The role of surface chemistry in recovery of minerals is central to several processes such as froth flotation, leaching, and electrostatic separation. In separation of base metals (eg, Cu, Pb, Zn, and Ni) by froth flotation of their minerals, usually sulphides, the attachment of these mineral particles, after hydrophobic collector addition, to air bubbles is used in operation. The stability of this bubble/particle attachment in both pulp and froth phases is dependent on the hydrophobic/hydrophilic ratio of surface species on individual mineral particle surfaces. The surfaces of individual mineral particles are a complex, distinctly nonuniform array of hydrophobic collector molecules and hydrophilic species (eg, oxidation products, adsorbed ions, fine particles, and precipitates). Hence, this ratio varies widely between different particles of the same mineral. It has been shown to determine whether particles report, correctly or incorrectly, to concentrate or tail (residue). To improve poor flotation recovery or grade, the analysis needed is the variation of this ratio by particle and as a statistical distribution between different mineral phases across a flotation circuit (eg, feed, successive concentrates, and tails). This requires surface analysis of a large number of particles with high spatial resolution and chemical speciation. In this Surface Science Western special issue article, methods to achieve this, using time-of-flight secondary ion mass spectrometry and principal component analysis, developed between the Ian Wark Research Institute and Surface Science Western over 25 years are reviewed with applications to flotation. They are equally applicable to interferences in leaching, extraction, and electrostatic separation processes.
