The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores.
A new idea was then proposed by combining the advantages of the Reflux Classifier, the Jameson Cell and the HydroFloat, while circumventing their shortages in providing a general solution for flotation.
Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

The rougher flotation behavior of a sulfidized copper ore was studied by a series of batch flotation experiments. Response surface modeling based on central composite design was applied to optimize and evaluate the effects of collector, depressant and frother dosages, solution pH and agitation rate on the copper recovery.

Fig. 12 (a) depicts the results of copper ore flotation with respect to sequence of collector addition in the presence of xanthate and thionocarbamate collector mixture in the ratio 1:1. The Cu recovery and grade is maximum when BBT was added first in the flotation cell.
A better solution may be to use a specially-designed flotation cell known tentatively as second-order flotation (SOF) cell. In this process, microbubbles are generated in a static mixer under highly turbulent conditions. A stream of CST is injected into the mixer so that bubble-particle attachment occurs under conditions of high-kinetic …

Flotation cell is usually composed of tank, aeration-agitation device, froth scraper, pulp discharge valve, and liquid level control mechanism. Flotation operations (roughing, scavenging, and cleaning), usually carried out in single or multiple tanks arranged in series, constitute a flotation system (Fig. 1).
The ore process flotation technique is enhanced by using external ultra-sonic waves. Compared to the classical flotation method, the application of ultrasounds to flotation fluids generates micro-bubbles by hydrodynamic cavitation.
These will allow for selecting the best equipment for each mineral and flotation stage (rougher, cleaner and scavenger). ...

Froth flotation is a selective separation process to separate valuable materials (recyclables, minerals, and other fine-size waste) from unwanted materials (gangue) using air bubbles in a general floatation tank, Jameson flotation cell, or flotation column.
Copper oxide minerals are important copper resources, which include malachite, azurite, chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment of copper oxide minerals in the mineral processing industry.

Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns.
A new method, staged flotation for effectively increasing the recovery of ultra-fine copper oxide ore with a new type of collector (ZH-1, C3-5 carbon chain xanthate) is proposed for the first time. The flotation process and mechanism were examined by flotation tests, entrainment rate analysis, laser particle size experiments and …
