EC Number: 241-034-8. ... Fluorspar is crushed, ground up and purified by froth flotation. First the lead and zinc sulphides are separated and the fluorspar treated with sulphuric acid forming hydrofluoric acid gas (HF). The acid grade fluorspar typically contains at least 97 percent calcium fluoride, as well as silica, mixed metal oxides and a ...


Froth flotation is the most important concentration method for beneficiating phosphate ores, . In this process, most collectors used worldwide are fatty acids obtained from vegetable species as byproduct of different industries, e.g ., tall oil, a byproduct of the paper industry [4], [6] .

The froth formed is skimmed off or allowed to overflow. Undesirable silica floats away with the froth, leaving a more pure ore concentration for further processing into pellets or other suitable material. In carrying out the flotation step, a collector agent capable of silica chelation is added to the pulp.


FROTHERS FOR THE FLOTATION OF SULFIDIC ORES. United States Patent 3865718. Abstract: A process involving the use of a new and improved class of frothing agents in the froth flotation of ores such as the sulfide ores of copper, molybdenum, lead, nickel and zinc, as well as for separating coal fines by flotation.

Gibbs, U.S. Pat. No. 2,449,984, describes the use of a series of thio carboxylic acid compounds as depressants for copper and iron sulfides in the froth flotation of molybdenite. Such compounds are defined as having the formula HS-R-COOH or HS-R-COSH in which R represents a saturated aliphatic group or the group CO.


investigation. Generally, froth flotation is the most widely used method for the treatment of ores containing pyrite in the industry because of its maturity in technology and advantage in economic cost. However, people often do not obtain satisfactory result in treatment of such ores by using froth flotation, especially in


Conditioning of the pulp with reagents was performed for 2 min for the depressant and 3 min for the collector at 2000 rpm at about 50% solids by weight. Flotation 150-2 process was performed at 1500 rpm. The flotation products (froth and sink) …


In this study, industrial lithium-ion battery (LIB) waste was treated by a froth flotation process, which allowed selective separation of electrode particles from metallic-rich fractions containing Cu and Al. In the flotation experiments, recovery rates of ~80 and 98.8% for the cathode active elements (Co, Ni, Mn) and graphite were achieved, respectively.


In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% …

This paper investigated the effects of using or not using potassium butyl xanthate (PBX) as a collector on the flotation kinetics of talc and chalcopyrite. By means of atomic force microscopy (AFM), Fourier-transform infrared spectroscopy (FTIR), a contact angle measuring instrument and particle size analyzer, the underlying causes behind the flotation rate changes …


The physical activities in a flotation cell involve the movement of solid particles driven by the flow of air and liquid. As illustrated in Fig. 1, Fig. 5, considering the different roles of pulp and froth in determining the cell dynamics, the flotation cell is divided into two sections: froth volume and pulp volume.The froth volume and pulp volume are then subdivided in the liquid …

importance of froth flotation, as a separation process, is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly. However, the discharge of organic, inorganic and metal


A froth flotation process is used for most feldspar ore beneficiation. Figure 8.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 (jm (20 mesh).
