Introduction Floatation is an extractive process where various minerals can be selectively extracted. Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu and Zn.

Generally, it was found that aging of suspensions prior to flotation is necessary in to allow the precipitation reaction to proceed to completion and consequently improve the removal process (Liu et al., 2009, Aziz and Beheir, …
The flotation process refers to the general term for the ore pulp flowing through each operation during ore flotation. In the flotation operation, different types of ore should be treated with different flotation procedures. Therefore, the flotation process can reflect the process characteristics of the ore.
The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).Separation of mineral particles by flotation takes advantage of …
Relation to Mining Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process. Cadmium is therefore produced in countries where zinc is refined, not necessarily in the …

Potash Flotation. The conditioner and reagentized salt-brine slurry is floated in a "Sub-A" Flotation Machine. In the circuit shown, roughing is accomplished in a "Sub-A" Free Flow Flotation Machine with no intermediate s or feed pipes. This allows the coarse sodium chloride waste product to flow through the machine unmolested.

Silver flotation process usually needs crushing, grinding and extraction three stages. The main equipment used in the extraction of silver includes jaw crusher, ball mill, spiral classifier, flotation machine, thickener, dewatering machine and other equipment. Here is the whole flotation process used in the extraction of silver: 1. Crushing Stage

Coal sludge, also known as slurry, is the liquid coal waste produced by mining activities. After mining, coal is crushed and washed to remove the surrounding soil and rock. The washing process generates huge amounts of liquid waste, and the mining process itself produces millions of tons of solid waste. Coal companies usually dispose of this waste by …

Too coarse ore particles (greater than 0.1mm) and very fine ore particles (less than 0.006mm) do not float well, and the recovery rate is low.. In the flotation of coarse particles, due to the larger weight, the shedding force of the ore particles increases.So, you need: (1) Use a sufficient amount of the most effective collector.

Collectors, some of the most important reagents used in the froth flotation process, are used to modify the surface properties of minerals to control how they float.
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in.
