Flotation Control System - BAGGI. The FLOTATION PLANTS are used in the mining industry to separate valuable minerals from gangue. The ore is extracted from the mine, ground in a mill and mixed with water and chemical reagents forming the pulp.
Regulating reagents used as activators increase the difference in the hydration of separate minerals, lowering the hydration of floated particles, which in turn activate their flotation. In general, the regulating reagents used as depressants have an action opposite to that of the regulators used as activators.
The mineral suspension was prepared by adding 2 g of single mineral sample (1 g fluorite and 1 g calcite for mixed binary mineral flotation) to the cell with 40 mL of DI water. After adding either HEDP or NaOL, the suspension was conditioned for 3 min to guarantee a sufficient interaction between reagents and minerals.
For more than a century now, flotation has been at the heart of the mineral processing industry. In this month's SPOTLIGHT FEATURE ARTICLE, direct from the November issue of INTERNATIONAL MINING magazine, John Chadwick examines new technologies and applications from some of the key players in mineral flotation, a technique that is so important to the global industry.

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. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

The amount of reagents used in electroflotation is considerably lower, and in some cases reagents are not needed at all. The widespread use of flotation for concentrating minerals has led to the construction of various flotation machines, with large cells up to 10–30 m 3 and high productivity. A flotation machine consists of a successive ...
They are used to improve the selectivity of a flotation process. They often make it feasible to separate minerals that were initially floated together. The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5.
from mineral processing flotation cells. A flotation cell is a reactor in which the three phases: solid, liquid, and gas, interact to separate valuable minerals that contain saleable metals, and waste minerals called gangue. In the case of mineral flotation, the solid is the ground rock particles, the liquid is water, and the gas is usually air.

Froth Flotation. Froth flotation has been used to separate discrete mineral particles since the early 1900's. The key to effective separation of the minerals depends on differences in the surface chemistry of the minerals to be separated. The process involves the separation of hydrophobic from hydrophyllic minerals.
Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp.
has proven practical solutions to separate these minerals. OXIDES AND SILICATE FLOTATION Gravity, magnetic and electrostatic separation processes are the traditional treatment methods used for beneficiation of oxide minerals. Advances in flotation reagents can make the recovery of oxides by flotation a more effective and economic process.
Flotation is the process used to separate and concentrate ores by altering their surfaces to a hydrophilic or hydrophobic condition. Flotation reagents are the chemicals used for the froth flotation process. They include pH regulators, slime dispersants, conditioning agents, collectors, resurfacing agents, wetting agents, and frothers.
Depressants and dispersants In mineral flotation the challenge is to maximize the recovery of desired minerals while rejecting unwanted gangue components. Depressants are required to give a low affinity to active sites on valuable mineral surfaces and a high affinity for gangue minerals and some sulfides.
The flotation separation of spodumene from other complex aluminosilicate minerals such as feldspar and mica, is problematic, due to their same active Al site for interaction with anionic collectors (Rai et al., 2011). In practice, the general method to accomplish effective spodumene flotation is to add amount of depressants associated with ...

Flotation Reagents & Collectors. Froth flotation is the most widely used industrial process for the separation of finely liberated minerals. The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals.
