Flotation tailings. The operator of a waste water treatment plant was looking for a pump with dry-run capability for his flotation system. In the flotation system, substances on the surface of the flotation tank are suctioned off using a rotating suction arm. Previously an eccentric screw pump had been used for this purpose.

The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).

1. Introduction. Froth flotation is an essential method to collect valuable minerals from gangue minerals, and is an industrial process involved with long time delay and multiple subprocesses (Aldrich et al., 2010, Mesa and Brito-Parada, 2019, Quintanilla et al., 2021, Shean and Cilliers, 2011).In the zinc flotation process, the zinc tailing is …

Large-scale application of filled coal mining technology has long been limited by conditions such as the cost of filling. Compared to traditional filling materials, coal flotation tailing filling materials (CFTFM) offers advantages such as low cost and excellent performance. The Box–Behnken response surface method was used to investigate the …

Alkylmorpholine has been employed as a reverse flotation collector of KCl. Alkylmorpholine sorption at the halite surface proceeds with high selectivity, creating the conditions necessary for ...

As an important strategic non-metallic mineral resource, fluorite has been widely used in various industrial fields, such as metallurgy, optics and semiconductor manufacturing, as well as fluorine-related chemical engineering. Since the major gangue minerals of fluorite ore are silicate and carbonate ones, flotation is the main …

Abstract. Common reverse flotation is difficult to separate efficiently picromerite with a high halite content. This work employed direct flotation to separate …

A novel chemical scheme for the flotation of rutile from eclogite tailings has been developed in this work. It consists of lead ion as the activator, sodium fluorosilicate (SF) as the depressant, and styryl phosphonic acid (SPA) and n-octyl alcohol (OCT) as the collector.By using the proposed scheme to treat a feed ore of 4.5% TiO 2, a rougher …

The successful flotation of KCl results from replacing the surface lattice K + ions with the ammonium ion of similar size; however, the ammonium ion cannot fit into smaller Na + ions at the halite surface; thus, no flotation is achieved. Following this rule, the flotation of most alkali halides with alkyl ammoniums was explained: all halides of ...

The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores.

For instance, the flotation process is performed with water containing 25–35% wt solid ratio and is consumed 1.9–3 m 3 water per ton of ore processed (Gunson et al., 2012; Li et al., 2019). However, the tailing slurry containing roughly 40–60% solids is discharged as a result of the process (Bleiwas, 2012). The primary environmental ...
