Clay Flotation: Effect of TTAB Cationic Surfactant on ...

One of the first conditions allowing the capture of a particle by an air bubble is surface hydrophobicity. An alkylammonium bromide surfactant (TTAB) was used to perform in situ hydrophobication of negatively charged illite clay particles. This treatment causes the neutralization of clay surface charge and the irreversible aggregation of particles. At a fixed amount of TTAB in solution, foams generated from illite …

control the colloidal properties of clay minerals on flotation. 1 Introduction Clay minerals are the primary natural materials consisting of fine-grained minerals. Clay minerals are commonly found in many mineralization as gangue minerals and they create problems in all steps of mineral processing. Difficulties in processing of high clay content ores are due to their different and complex structures. The presence …

(PDF) EFFECT OF CLAY MINERALS ON FROTH STABILITY IN ...

Their extremely small particle sizes, along with their very high surface area make clay minerals highly reactive and responsive to changes in the processing environment. The various deleterious roles of clay minerals in froth flotation were reported by a number of authors (Bulatovic et al, 1999;Bulatovic, 2007;Jorjani et al, 2011). They include slime coating on the mineral surfaces as well as air bubbles …

Rheology measurements for flotation slurries with high ...

01/11/2016· As a result of the complexity of some ores with high clay contents, rheology is becoming a useful tool to investigate the effect of high viscosities in mineral processing operations including flotation. It has been observed that the presence of clay minerals in flotation slurries has a detrimental effect on concentrate grade and recovery. Concentrate grade is affected by the mechanical entrainment of clay …

Role of Montmorillonite, Kaolinite, or Illite in Pyrite ...

It is widely acknowledged that clay minerals have detrimental effects on the process of flotation, but the mechanisms involved are still not fully understood. In this work, the effects of montmorillonite, kaolinite, and illite on pyrite flotation were investigated from the perspective of various structures of clay minerals. Flotation tests suggested that the detrimental effect of clay minerals on the flotation of pyrite increased …

Beneficiation and mineral processing of clay minerals

7) CLAY MINERALS Clays are formed from rocks which have been weathered by physical and chemical action, (e.g. orthoclase, a mineral found in granite, reacts with H2O and CO2 from the atmosphere as follows): K2O.Al2O3.6SiO2 + 2H2O + CO2 → Al2O3.2SiO2.2H2O + 4SiO2 + K2CO3 orthoclase kaolin clay Clay is a naturally occurring material composed primarily of fine grained clay minerals (Clay …

Lime use and functionality in sulphide mineral flotation ...

01/11/2019· Flotation at high ionic strength has been reported to enhance the flotation of the inherent hydrophobic minerals (Haga et al., 2014), since the electrical double layer is compressed and attachment to the air bubbles enhanced (Lucay et al., 2015), and also finer bubbles are produced (Jeldres et al., 2016). Also, the flotation froth is more persistent and stable in the presence of dissolved salts. This is …

Influence of Clay on Mineral Processing Techniques ...

This PhD thesis investigated the influence of kaolin and bentonite clays in the ore on flotation, filtration and centrifugal concentration. The results showed that the presence of particularly bentonite in the ore had a detrimental effect on flotation and filtration. The information generated from this work will advance our knowledge as well as provide important information for plant metallurgists. The project, therefore, …

To Float or Sink: A Brief History of Flotation Milling

tation can be used in processing metallic orcs (e.g., copper, lead, zinc, gold, silver) or non-metallic ores (e.g., clay, phosphate, coal). Flotation is the most widely used process in the world for extracting min­ erals. The process also recovers several metals from a single ore body into two or more concentrated prod­ ucts. The development of flotation solved an indus­ try dilemma and ...
