In flotation practices, as particles become finer, such as smaller than 20 µm, process efficiency declines markedly. Selective agglomeration of fine particles is a technique to enhance the recovery of fine valuable minerals in flotation circuits. Different agglomerating methods have been introduced and tested. One method that has recently …
This particular flotation plant studied shows a high rate of recovery of the value mineral. To gain more confidence in these results, the flotation rate was benchmarked against flotation rates measured in other large flotation plants, treating a similar value mineral and with a similar collector type (Table 3).
Flotation continues to be one of the most important tools in mineral separation and processing of complex ores. Today, while the mining industry is focused …
The paper describes a procedure to tune a grinding circuit in order to maximise the economic efficiency of the flotation plant.

Flotation is a widely employed method in mineral processing and beneficiation for effectively separating mineral particles.
1. Introduction. Flotation is a physicochemical process that allows the separation of minerals, such as copper sulfide minerals and molybdenum, from the remaining minerals that form most of the parent rock substrate, including contaminants, such as arsenic minerals (Bruckard et al., 2010).The separation is performed on milled …
