Sulfonated modifiers for froth flotation

Used in a reverse froth flotation process in a medium for the separation of beneficiary and gangue from a mineral ore, the modifiers of applicants invention unexpectedly provide improved separation and selectivity toward concentrate or tailings, improved recovery of beneficiary as measured by weight of beneficiary recovered as a proportion of ...

Flotation reagents types and working principles

Flotation reagents refer to the agent that used in mineral flotation process, which can adjust the flotation behavior of minerals thus achieving a good effect of mineral separation.currently using flotation reagents is the most flexible, effective, and convenient method of controlling flotation process.the commonly used flotation reagents can be mainly divided into three types according to ...

Interactive effect of minerals on complex ore flotation

Froth flotation is the most effective industrial method used to separate fine-grained minerals. the main problem of complex ore flotation is the negative effect of interactions among minerals in slurry, leading to variation in surface properties during separation.

Flotation of salt

Abstract. salt-type minerals flotation is discussed, based mainly on experiments on magnesite, dolomite and calcite. among the parameters affecting flotation, the following are examined crystal structure, solubility of minerals, surface charge, collectors, organic and inorganic modifiers, adsorption, contact angle and floatability.

Polymers as bubble surface modifiers in the flotation

Previous research has shown that dosing polymers directly to the saturator of a dissolved air flotation daf process in replacement of upstream coagulation can achieve algae removal comparable to that of conventional treatment, as a result of bubble modification.

Froth flotation in mineral processing

Froth flotation is the most effective separation in mineral processing. william haynes was the first who attempt to separate minerals from gangue using oil and air bubbles. he gives the name froth flotation to the method, and he is known as the person who discovered froth flotation.

A brief review of pulp and froth rheology in mineral

In most flotation pulps, a low solid concentration is generally used. the more dilute the pulp, the cleaner the separation .as can be seen in figure 3, when the ug2 and great dyke feed solid concentration exceeds 25 vol., a discernible increase in the apparent viscosity of the feed samples could be detected, which would result in rheological complexities in the separation process.
