Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Effect of Clay Rheology on Flotation of a Refractory Gold Ore

Oct 10, 2016· The results showed that bentonite clay adversely affects floatability of pyrite while kaolinite clay had a lesser influence on flotation of pyrite. The addition of Ca2+ ions to the pulp containing bentonite modified the rheological characteristics and in turn improved the pyrite flotation.

The interaction of clay minerals with gypsum and its

Jun 01, 2015· Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.

Selective Flotation an overview ScienceDirect Topics

For a fixed interaction period, flotation recovery of sphalerite was unaffected for an initial cell density in the range of 10 2 –10 8 cells/mL. Beyond 5×10 8 cells/mL, flotation recovery of sphalerite was found to decrease sharply. Floatability of galena, on the other hand, was found to decrease gradually with increase in initial cell density in the entire range of 10 2 –10 9 cells/mL.

Flotation Kinetic studies The results of the experiments from 1 to 4 are given in Table 1 and are also depicted in Figure 1. From the fi gure it is clearly evident that the P 2 O 5 recoveries were much higher when promoters are used. Out of the three promoters tested, urea was found more effective than AOS and LABS. Conventional fl otation tests

A Brief Review of Pulp and Froth Rheology in Mineral Flotation

In mineral flotation, rheological problems have limited the efficient upgrading of low-grade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.

Effect of pH on the Recovery and Grade of Base Metal

[10]. The use of co collectors or promoters in flotation is well established [11]. One of the most important aspects of froth flotation is the formation of a froth in which the valuable minerals are retained for further up grading. Thus the presence of a surface-active or frothing agent, either as a
