Reagent selection is based on sampling the mineral and doing laboratory flotation to screen the type of reagent and its application for direct or reverse flotation.Due to the different ore properties, the dosage range of flotation reagent is also different. Even for the same type of ore, there are also some differences in the formation of ore deposit, so the content of useful minerals and gangue vary, and the dosage of flotation reagent required in the flotation.
Heyes and Trahar determined the potential dependence of the rate of flotation of chalcocite with ethyl xanthate as collector. Control of solution pH is one of the most widely used methods for depressing flotation. The depressant action of alkalis results from an increase in the rate of dissolution or oxidation of mineral surface.Flotation agents are chemical agents used in the mineral flotation process which can adjust the surface properties of the minerals, increase or decrease the floatability of the minerals, and make the pulp properties and foam stability conducive to mineral separation. Common flotation agents are collectors, foaming agents, inhibitors, activators, dispersants, flocculants and defoamers.

The introduction of flotation reagents into the liquid phase of the pulp and subsequent adsorption along the liquid gas and solid liquid interfaces create conditions for the selective flotation of specific mineral particles. There are three principal types of flotation reagents.Mineral Processing Research Unit (MPRU), Rondebosch, South Africa Reagents are added to the flotation process of Merensky Reef ores to achieve specific functions that enable the separation of valuable minerals from gangue minerals on the basis of the difference in their surface properties.
Jan 01, 2017 Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals. Most of these reagents such as cyanides are toxic in nature and.Xinhai helps customers to determine the scientific and reasonable flotation reagents system according to the results of mineral processing test, and continuously adjusts the flotation reagents system in the production, so as to obtain the ideal technical and economic indicators.
Xanthate, as the flotation collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of flotation.Xanthate is commonly used in the flotation process of sulfide minerals. Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector. . It is light yellow, soluble in water and.Handbook of Flotation Reagents Chemistry, Theory and Practice is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. This book consists of three distinct parts part 1 provides detailed description of the chemistry used in mineral processing industry part 2.
Nov 13, 2018 Handbook of Flotation Reagents Chemistry, Theory and Practice is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. This book consists of three distinct parts part 1 provides detailed description of the chemistry used in mineral processing.There are than 20 types of mineral flotation. Universal separation method, because by using flotation can be separated almost all minerals. It is used for all types of ores and minerals (chalcopyrite, molybdenite, galena, sphalerite, gold, talc, mica, carbon, rare earth mineral, uranium minerals.
Flotation is the most widely used method for the concentration of fine grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents. By altering the.Handbook of Flotation Reagents Chemistry, Theory and Practice Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the theory, practice, and chemistry of flotation of gold, platinum group minerals (PGMs), and the major oxide minerals, along with rare earths.
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral water slurry.

Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) air addition rate. Many other parameters may vary such as feed rate, particle size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itself.
