Depressants and activators are used to selectively separate one mineral from another. Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others. There are a number of cells able to be used for the flotation of minerals. these include flotation columns and mechanical flotation cells.

What is the Fluorite Beneficiation Process?

The common fluorite beneficiation processes include gravity separation and fluorite flotation process. Gravity separation process can be used for coarsegrained fluorite ore. And fluorite flotation process can be used to process fluorite ore that is associated with impure minerals and the granule of value mineral is so tiny. Fluorite is often associated with quartz, barite, calcite, sulphide

(PDF) Managing clay minerals in froth flotationA critical

Another adverse effect of clay minerals on mineral flotation is. the dilution of concentrate grade caused by clay minerals. entering the froth through mechanical entrainment.

Mineral processing

Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others. Examples of these include CN , used to depress all sulfides but galena and this depressant is believed to operate by changing the solubility of chemisorbed and physisorbed collectors on sulfides.

pulp surface. Collector addition also affects froth formation. Too much can inhibit froth stability and 'flatten the circuit', too little and not all mineral surfaces will be coated. Either way, recovery goes down. Lime is often used in flotation to increase the alkalinity of the pulp. An alkaline pH increases the volume

Dodecyl Mercaptan Collector for Sulfide Ores

An analysis of a commercial flotation operation cannot be undertaken without considering the effectiveness and characteristics of the mineral collector. While many operations show satisfactory metallurgical performance, others are characterized by low recoveries of certain metals. Factors such as inadequate liberation, surface oxidation of sulfide minerals, or the adverse or depressing action

Introduction to Mineral Processing Chevron Phillips Chemical

Introduction to Mineral Processing. Chemical modification of these properties enables the mineral particles to attach to an air bubble in the flotation cell. The air bubble and mineral particle rise through the pulp to the surface of the froth or foam that is present on the flotation cell. Depressants are chemicals that inhibit the

Jul 09, 20190183;32;The most commonly used collector for flotation chalcopyrite is xanthate, chalcopyrite is easy emerged in a wide pH range (3 to 12). Chalcopyrite is susceptible to inhibition by cyanide and oxidants in the alkaline pulp. Excess lime and sodium sulfide and ammonium sulfide inhibit chalcopyrite in alkaline slurries.
